　　On June 2, 2016, the General Assembly of the International Engineering Union was held in Kuala Lumpur, establishing the status of official member of China’s international undergraduate engineering degree mutual recognition agreement, the Washington Agreement. This means that China’s engineering education professional accreditation system has been internationally recognized and China’s higher education will truly go global. The concept of professional accreditation in engineering education is student-centered, result-oriented, focusing on continuous improvement, and focusing on students’ future development needs. Therefore, the course “Design and Calculation of Non-ferrous Metals”, which is very professional and practical, has a very important role in establishing students’ concepts and awareness of engineering design and application, and cultivating students’ ability to solve complex engineering problems in metallurgy.

However, this course generally has old and boring contents, fragmented and unsystematic structure, abstract and unspecific process flow and operation equipment, and cannot be well practiced in the traditional teaching process, which leads to low quality of teaching and makes it difficult to effectively improve students’ ability of engineering design and application.

　　In the teaching process, three-dimensional teaching can effectively stimulate students’ interest in learning and independent learning consciousness, and improve students’ learning effect. Stereoscopic teaching pursues the comprehensive and in-depth integration of theory and practice, which can stimulate students’ learning enthusiasm and enhance learning effect in all aspects and at all levels with the help of paper teaching materials, physical teaching aids, electronic teaching plans, multimedia courseware, virtual simulation training system and online teaching platform. Aiming at the requirements of professional certification of engineering education, the three-dimensional teaching mode of Nonferrous Metals Design and Calculation is explored with student-centered, result-oriented and continuous improvement, aiming at establishing students’ concepts and awareness of engineering design and application, cultivating students’ ability to solve complex engineering problems in metallurgy and improving their comprehensive quality.

　　1 Combine with the requirements of engineering education professional certification, clarify the course objectives and optimize teaching contents

　　Through the interpretation and decomposition of the index points of metallurgical engineering graduation requirements, the course “Non-ferrous Metal Design and Calculation” requires students to master the basic concepts, procedures and contents of metallurgical plant design, master the selection and design of metallurgical plant process, balance calculation, equipment selection and design, plant layout and workshop design, understand the economic analysis of non-ferrous metallurgical plant design, establish the concept of engineering design and application Students will be able to understand the economic analysis of non-ferrous metallurgical plant design, establish the concept and awareness of engineering design and application, and develop the preliminary ability to design and calculate metallurgical plant process and its equipment. On this basis, we will sort out the knowledge of this course and optimize the teaching contents.

　　(1) Construct the knowledge framework, grasp the main line of teaching, and highlight the important and difficult points.

Non-ferrous metal design and calculation” course is a compulsory course for undergraduate students of non-ferrous metallurgy, which aims to lay the necessary basic knowledge for students of non-ferrous metallurgy in non-ferrous plant design, technical transformation and transformation of scientific and technological research results of non-ferrous metallurgy into productivity. Plant design covers feasibility study, preliminary design and construction drawing design, construction, commissioning and acceptance, etc. The course content focuses on preliminary design and construction drawing design, and the main line is plant site selection, general plan design and process design.

The process design is rich in content, in addition to process selection and design, material and energy balance, equipment selection and design, plant layout design, piping design, but also includes technical and economic analysis and safety and environmental protection. The teaching process should grasp the main line, using multimedia courseware, virtual simulation training system, network teaching platform and other three-dimensional teaching mode in the seemingly boring content to find its inner connection and law, vivid image, layer by layer, in-depth, focused, so that students effectively master the design and calculation of non-ferrous metallurgical plant processes and equipment.

　　(2) Highlighting the cultivation of ability and improving students’ engineering awareness and practical ability.

The teaching goal of “Design and Calculation of Non-ferrous Metals” is to cultivate students’ ability to analyze and solve problems by applying basic theories and research methods, and to emphasize the cultivation of students’ practical and engineering application ability. Around the teaching content, it is combined with metallurgical field production examples to reflect the professional and practical characteristics of the course. When teaching chapter content, we reasonably arrange examples and cite typical cases and engineering examples to guide students to actively think, analyze and solve problems, and improve their active participation and engineering awareness.

　　(3) Update the teaching content, broaden students’ knowledge and adapt to social development.

Non-ferrous metal design and calculation” course involves the content of traditional metallurgy, but with the development of society, the actual production involves a lot of new metallurgical technologies and processes, which need to be reflected in the lectures, such as pressurized hydrometallurgy, biological hydrometallurgy, oxygen-rich flash copper refining, direct lead refining, etc. have been industrialized. Each chapter of the teaching content should focus on the frontier of the discipline, introduce new technologies and processes of metallurgy, broaden students’ knowledge, adapt to the development of the times, and cultivate talents to meet the needs of society.

　　2 Adopt student-centered and three-dimensional teaching mode to strengthen teaching effect

　　The professional certification of engineering education is an education model based on learning output (OBE), which emphasizes what students learn. Therefore, the lectures should take the training objectives and graduation requirements as the reference point, and adopt a three-dimensional teaching mode to reasonably assess whether the students reach the graduation requirements.

　　Design and Calculation of Non-ferrous Metals is based on classroom teaching, supplemented by extra-curricular learning, classroom and extra-curricular assignments, and PowerPoint group presentations. The content involves a large number of equipment drawings, plant layout drawings, balance calculations and process design parameters. During classroom teaching, CAD drawings can be embedded to show equipment body diagrams, equipment link diagrams, floor plans, etc.; virtual simulation technology can be used to present metallurgical plant floor plans, show virtual scenes of process flow, independent smelting operations, etc.; flash can be incorporated to analyze the working principle of equipment and demonstrate the process flow, etc.; and “question-based “, “heuristic”, “comparison”, “discussion”, “summary “and other methods of teaching, to guide students to actively think about the problem, analysis, problem solving.

Meanwhile, for the important and difficult knowledge in the course, special class discussion sessions are arranged and a certain amount of homework is assigned. The knowledge points involved in the exercises cover the key points and difficulties of the lecture content to strengthen and consolidate students’ mastery of the knowledge points. In addition, some typical cases or knowledge points are selected and students are allowed to form teams to make their own classroom materials to explain on the stage, and the teacher and other students can ask questions and add to the content of the explanation to stimulate students’ independent learning awareness and enhance the learning effect. In this process, students can also develop non-technical skills such as organizational management, coordination, teamwork and communication skills, so that students can better adapt to the needs of society and employers.

The second classroom is opened outside the classroom, teachers and students can share class resources, question and answer exchanges, exercise counseling and explanation and online test self-assessment by WeChat/QQ group and online platform, etc. to guide students to take the initiative to think and actively summarize, deepen students’ understanding and mastery of basic concepts, basic principles, processes and balance calculations of the course, so that students can benefit and promote all students to reach graduation requirements. 　　

3 Finding target shortcomings, identifying problems and continuously improving course quality

　　Based on the analysis of the OBE course assessment results, and taking into account the problems reflected by the usual homework, students’ questions, QQ/WeChat Q&A, students’ evaluation of teaching, peer evaluation of teaching, and teaching supervisors’ listening to classes, we search for the shortcomings of the course objectives, put forward targeted improvement measures in teaching, and purposefully add them to teaching and training to strengthen students’ mastery of knowledge points and training of weak links of index points. For example, based on the analysis of OBE course assessment results, the following problems were found.

(1) Some students have certain deficiencies in the differentiation and application of different concepts and specific knowledge points.

(2) Some students have incomplete mastery of basic theory and inappropriate calculation methods.

(3) Students’ ability to apply theoretical knowledge to analyze practical problems is not comprehensive enough. In view of this, the subject group put forward the following improvement suggestions after discussion.

(1) The subsequent teaching should be moderately comparative and analytical to distinguish different concepts and strengthen students’ mastery and application of specific knowledge points in design.
(2) Adopt in-class homework, open up second classroom and stage quizzes to strengthen students’ real-time mastery of calculation theory and methods.
(3) Continue to strengthen the teaching and analysis of engineering cases. Through the closed-loop management mechanism of “evaluate – improve – re-evaluate”, strengthen the result-oriented teaching and promote the achievement of course objectives, the quality of course teaching will be continuously improved.

　　4 Conclusion

　　Engineering education professional certification is a systematic project for all students and requires all students to meet graduation requirements. During the lectures, student-oriented, three-dimensional teaching methods such as electronic lesson plans, multimedia courseware, virtual simulation training system and online teaching platform can stimulate students’ interest in learning at multiple levels and in all aspects and improve the quality of lectures.

In addition, based on the OBE concept, finding the shortcomings of course objectives, targeting in teaching, insisting on goal orientation, focusing on continuous improvement and being practical, can effectively improve students’ ability to analyze and solve problems and promote the achievement of course objectives and students’ graduation requirements.

Forging – is one of the oldest methods of metalworking. These items are beautiful and do not change over the centuries. Iron gates – this indescribable beauty, which a man puts into his soul, is the embodiment of his imagination into reality.

Wrought iron gate

Guests are concerned about the first thing that lifts up the house, the gateway. With your own hands iron gates build a difficult, but very real. It will require forging equipment, tools, forgeries and anvils. Horn – the main requirement for the quality of her work metal furnace is the constant high temperature. Due to this, metal can be given absolutely any form.

Wrought iron open fence gates For the production of each project requires a large number of different tools, it can be up to several hundred pieces. Before you start making iron gates, it is very important to study the kind of metal, when heating occurs within the structure, what kind of changes in the way they behave. You must learn to look at the sensory material more his expressive characteristics and be able to distinguish them.

The forge door starts making sketches. It is necessary to obtain the necessary amount of metal and a pair of pins, preferably square in cross-section, they fit in the frame. Given all the dimensions of the paper on which the sketch was made, start cutting the parts. Then, they are drawn separately from the arch. The finished coils are attached to each other and fixed to the target frame

In order for the wrought iron door to be beautiful, you have to save the plane. In the adoption of welding it is important to have a knockdown resulting in a slag joint in time, as if you do not do this, a crack may be developed and everything will start to fail, there will be a hole and it will provide moisture to the steel, eventually leading to the destruction of the entire structure corrosive good access.

The art of finishing the work to be treated with sandpaper and paint with black paint. It can be covered with gold enamel, it is elegant combined with black.

Sliding iron gates

Pendulum gates – it is beautiful, they have the advantage of simple structure, but sliding iron gates are more convenient. In addition, they are more practical. Wrought iron sliding gates have many advantages: using one-piece design – it will do without strain, does not require cleaning area in front of the door, especially in winter, can be placed regardless of the large production, and made in any width opening in the home.

Sliding doors can also be made with your own hands, as this is the design that requires research. It is very simple, there is a net counterjib part, attached to it in the form of various attachments. The process of manufacturing sliding doors is too much clumsy and consists of two stages. First, the preparation of the canvas, and then made the installation of the fabric on the base.

But no matter how these doors are – hinged or sliding, the main thing – to make them well. Qualitative execution will give the house a unique personal style.

　　With the improvement of living standards, people’s requirements for the level of living have also been greatly improved, so it is necessary to focus on improving the quality of construction. The use of concrete can improve the quality of construction to a certain extent, it concrete engineering construction is a more technical work, so his construction must be carried out by professional and technical personnel, thus ensuring the quality of construction projects.

With the introduction of new technologies and materials, improved construction techniques and improved construction equipment, thus improving the efficiency of the construction of architectural concrete, it can be combined with the reinforcement very firmly, forming a particularly strong, compressive, earthquake-resistant reinforced concrete structure, is an integral part of the project, there is also, with the continuous improvement of technology, the quality of concrete is also constantly improving, the use of its scope is also Gradually expanding, in the construction project has a pivotal role.

　　1 The application of architectural concrete construction technology

　　In our daily life, we often see cracks in buildings and walls falling off, this is due to the construction process of architectural concrete is affected by human, temperature, technology and other factors, so in the construction process, the operator must make a comprehensive consideration and analysis for better construction.

The structure of concrete has to control its different crack widths due to different climatic conditions and weather conditions, and our country mainly adopts technical means of innovative construction process and strengthening supervision to prevent and control the problem of cracks in buildings.

To ensure the overall quality of the project and to avoid cracks and falling off, the supervision and management of the construction personnel should be strengthened, and the material of concrete should be used in a reasonable and scientific way.

If the cracks appear in the building after the construction, we will not be able to make up for them, which will cause the deviation between the ideal construction effect and the real building, thus affecting the quality of the building.

　　2 Formwork construction in building concrete engineering

　　The first step in building concrete construction is to prepare the formwork, which is of two types – steel and wooden. Regardless of which of the two types of formwork is used for construction, the formwork must be cleaned before construction to ensure that the surface of the formwork is clean and free of cracks.

In the construction project, if the wooden formwork is chosen, it should be wetted before use, and then carry out the later links to ensure that the construction is carried out smoothly, and there is a comprehensive inspection of the wooden formwork to see if it is complete, there is no defect, if there is a crack phenomenon, mortar and linoleum can be used to seal it, so that the formwork is complete, the texture is tight and strong.

Once the steel formwork is chosen, it should be used to paint the surface with release agent before use, and ensure that the painting technique is skillful, evenly and completely paint the formwork well, resolutely avoid the place of leakage, and ensure that the formwork is intact and clean.

The choice of the board has a certain impact on the quality of construction, the required template should be meticulously observed to avoid abnormalities, only good security template can play a supporting role, once the position deviation, to be adjusted in a timely manner to ensure the quality of the project, in the removal of the template, to fully grasp the concept of time, not too early and not too late, must be able to reach a certain bearing capacity Only after the formwork can be removed, otherwise problems will occur.

Many factors in the construction process of concrete projects cause the surface of the building is prone to pockmarked conditions: the surface of the formwork is rough, not enough cleaning; sometimes there is concrete sticking to the formwork when it is removed; the formwork is not checked before use, there are often gaps. Only in the construction of the causes of the above problems to effectively grasp, and strive to weaken the problem, so that the quality problems do not appear in the subsequent construction.

　　3 The main points of pouring and maintenance technology in the construction concrete project

　　3.1 Concrete pouring points

　　3.1.1 Points before pouring.

First, the debris such as soil, garbage and oil within the formwork should be removed to ensure the cleanliness of the formwork.

Secondly, the concrete should be mixed. Before mixing, the amount of various materials can be determined according to a certain ratio according to the requirements of concrete, and the moisture content of the materials should be repeatedly tested and the amount of water used should be adjusted in time. Then, the material should be loaded with stones first, then with cement, and finally with sand.

Finally, in order to ensure the quality of concrete, the concrete should be fully mixed, and when the concrete is transported, the concrete pump truck should not stop but work continuously, and if segregation will occur, the residual concrete should be flushed.

　　3.1.2 Concrete pouring technical points Before concrete pouring, the following aspects need to be carefully checked to fill in the concealed works record sheet with the inspection results.

First, checking the elevation, location, size, strength and stiffness of the formwork.

Second, the location, quantity and protective layer thickness of the reinforcement and pre-buried parts; in addition, before the concrete is placed, the debris and oil of the reinforcement should be removed from the formwork, silt and debris should be removed, the gaps and holes of the formwork should be blocked, and the wooden formwork should be moistened with clean water, but there should be no water accumulation. At the same time, when the concrete is poured, it should be poured in layers from low to high, and the thickness of each layer should be determined according to the reinforcement of the structure and the pounding method.

Before pouring the vertical structure concrete, the bottom should be filled with cement mortar with the same composition as the mortar in the concrete; no segregation should occur in the concrete pouring; if the pouring height exceeds 3m, the concrete should be made to fall by using a chute or vibrating chute and a string of simple. In the process of concrete pouring, the condition of formwork, reinforcement, bracket, pre-built parts and reserved holes should be observed repeatedly, and if deformation and displacement are found, measures should be taken in time to deal with them.

　　3.2 Concrete maintenance technology

　　In order to make the construction quality of concrete to be effectively guaranteed, so that the project to play the maximum economic benefits, to carry out relevant maintenance of concrete. A common problem in building construction is about the maintenance of roof panels, usually the roof panels are larger and higher in height, due to rapid evaporation is easy to produce moisture loss is also fast, but also increases the water loss in the early stage of concrete pouring.

To solve this kind of problem should be flattened its surface, and sprinkle the right amount of water to keep it in a wet state, and then covered with a film on top, use some insulation materials to its maintenance. Insulation is the most important step in the maintenance of concrete, which can effectively ensure that the surface temperature of the concrete is affected by a series of changes in environmental factors. Pay attention to the temperature difference between the various levels during the curing period, and keep the temperature difference strictly below twenty degrees.

Scientific and reasonable concrete maintenance program before the construction of mass concrete is an essential prerequisite for preparation, the development of a program to meet the design requirements will achieve twice the result with half the effort. After the demoulding of the concrete encountered a sudden change in weather conditions, it should be insulated or insulated at the first time to prevent the concrete from generating excessive temperature stress due to the temperature difference.

　　Conclusion

　　The discussion of architectural concrete construction and maintenance techniques has given us a further understanding of architectural concrete and its significant impact on our living environment.

The construction of architectural concrete is a technical discipline, and its quality is related to the overall quality of the building. Before construction, we must choose high-quality concrete to ensure that the construction process is carried out perfectly, and after construction, we must also carry out timely maintenance of the building to improve the service life of the building. In order to fully ensure the quality of the project, we should focus on improving the construction technology and techniques of concrete.
