Building forgings play an important role in the construction industry, whose quality directly affects the structural safety and stability of buildings. This paper will introduce the production process of building forgings in detail, including the selection of raw materials, blank manufacturing, heat treatment, processing and forming, and quality inspection.
Process flow
Selection of raw materials
The production of building forgings first needs to select the raw materials that meet the requirements. Considering the particularity of the construction industry, raw materials should have high strength, corrosion resistance, earthquake resistance and other properties. Commonly used raw materials include steel, aluminum alloy, copper alloy and so on.
Blank manufacturing
Making blank is an important link in the production process of building forgings. The quality of blank directly affects the quality and production cost of forgings. The method of manufacturing blank includes casting, forging, powder metallurgy, etc., and the appropriate method is selected according to the specific needs.
Heat treatment
Heat treatment is a key step in the production process of building forgings, and its main purpose is to improve the performance of materials, including improving strength, hardness, wear resistance and so on. In the heat treatment process, the temperature and time should be strictly controlled to prevent overburning, cracking and other phenomena.
Process forming
The forgings after heat treatment need to be processed to meet the actual needs of the building. Processing molding mainly includes cutting, grinding, polishing and other steps. In addition, some special shape forgings also need to use die casting, extrusion and other processes.
Quality inspection
Quality inspection is an important link to ensure the production quality of building forgings. Testing items should include material composition, physical properties, mechanical properties and other aspects. At the same time, according to customer requirements, non-destructive testing and other methods can be added to ensure the quality and safety of forgings.
Key technology
Chemical composition and physical properties of raw materials
The chemical composition and physical properties of raw materials have an important impact on the quality and performance of forgings. Therefore, when selecting raw materials, it is necessary to fully consider the stability of its chemical composition, the superiority of physical properties and economic factors.
The processing technology of blank
The processing technology of blank has an important influence on the quality and production cost of forging. In actual production, the appropriate processing technology should be selected according to the material properties and product needs, such as casting, forging, powder metallurgy and so on. At the same time, we should pay attention to the waste generated in the blank manufacturing process, try to improve the utilization rate of materials and reduce production costs.
Temperature and time of heat treatment
The temperature and time of heat treatment are the key factors affecting the quality and performance of forgings. In the heat treatment process, the temperature and time should be strictly controlled to prevent over-burning, cracking and other phenomena. At the same time, pay attention to the cooling rate and medium after heat treatment in order to better control the organization and properties of the material.
- Processing and molding equipment and tools
Machining equipment and tools have an important impact on the accuracy and quality of forgings. In actual production, it is necessary to choose the appropriate equipment and tools, such as cutting machines, milling machines, drilling machines, grinding machines, etc. At the same time, attention should be paid to the accuracy and maintenance of equipment and tools to ensure their normal operation and extend their service life.
- Methods and standards for quality testing
The method and standard of quality inspection is an important link to ensure the quality of forging and customer satisfaction. In actual production, it is necessary to choose the appropriate testing methods and standards, such as mechanical property testing, metallographic analysis, non-destructive testing, etc. At the same time, it is necessary to pay attention to the accuracy and fairness of testing in order to better control product quality and market competitiveness.
Production precautions
The selection of raw materials should meet the standard
Raw materials are selected in accordance with relevant standards and specifications to ensure the stability of their chemical composition and physical properties. At the same time, the economy and recyclability of raw materials should be considered in order to better reduce production costs and protect the environment.
- The processing of blank requires fine operation
The processing of blank requires fine operation to avoid problems such as over-cutting, under-cutting and residue. At the same time, it is necessary to pay attention to the dimensional accuracy and surface quality of the blank in order to better control the quality and production cost of the forging.
- Pay attention to the control of temperature and time during heat treatment
During the heat treatment process, attention should be paid to the control of temperature and time to prevent over-burning, cracking and other phenomena. At the same time, pay attention to the cooling rate and medium after heat treatment in order to better control the organization and properties of the material. In the heat treatment process, attention should be paid to the requirements of energy saving, emission reduction and environmental protection, and advanced heat treatment technology and equipment should be used to reduce energy consumption and pollutant emissions. 4. Pay attention to the maintenance of tools and equipment when processing
When processing and forming, we should pay attention to the maintenance of tools and equipment to ensure its accuracy and service life. At the same time, it is necessary to pay attention to the selection and configuration of equipment and tools in order to better meet production needs and improve production efficiency. In the process of processing, attention should be paid to safety issues and operational norms to avoid safety accidents and quality problems. 5. Quality testing to be comprehensive and careful Quality testing is an important link to ensure forging quality and customer satisfaction. Quality testing should be comprehensive and detailed, including material composition, physical properties, mechanical properties and other aspects of the test. At the same time, it is necessary to choose the appropriate testing methods and standards according to customer requirements in order to better meet customer needs and improve market competitiveness. In the process of quality testing, attention should be paid to the accuracy and fairness of data in order to better control product quality and enhance corporate reputation. Conclusion The production process of building forgings is an important link to ensure the safety and stability of the building industry. In construction
