As a kind of metal component with high performance and high safety, building forgings are playing an increasingly important role in the construction industry. In this paper, the mechanical properties and quality control of building forgings will be elaborated in detail, in order to provide useful reference for related industry personnel.
First, mechanical properties of building forgings
Building forgings require a range of excellent mechanical properties to ensure their stability and safety in building applications. The following are the main factors affecting the mechanical properties of building forgings:
Tensile strength: Tensile strength is a measure of the ability of forgings to resist damage under tensile load. In order to meet the high strength requirements of building structures, building forgings must have high tensile strength.
Hardness: Hardness is a measure of the ability of the surface or interior of the forging to resist local deformation and damage. In the construction industry, the hardness of forgings needs to meet certain standards to ensure that there is no excessive wear or deformation during use.
Fatigue strength: Fatigue strength is a measure of the ability of forgings to resist fatigue damage under alternating loads. Because the building structure will be subjected to different forms of force during use, the fatigue strength of the forging is crucial to the safety and durability of the building.
In order to optimize the mechanical properties of building forgings, the following approaches can be taken:
Improve raw materials: the selection of high-strength, high-toughness alloy materials as forging raw materials, so as to improve the basic mechanical properties of forgings.
Optimization of forging process: By optimizing forging process parameters, such as heating temperature, deformation degree, cooling speed, etc., to obtain a more uniform, fine grain structure and ideal microstructure, so as to improve the mechanical properties of forgings.
- Quality control of building forgings
In order to ensure the quality and safety of building forgings, strict quality control measures must be taken. The following is an analysis of the existing problems and causes of building forgings in the current market, as well as measures to improve the quality control of building forgings:
Problems and reasons: The main problems of building forgings in the current market include mechanical properties not up to standard, size deviation is too large, surface defects and so on. These problems are mainly due to improper procurement of raw materials, unstable production processes, aging production equipment, non-standard operation of employees and other factors.
Quality control measures: In response to the above problems, the following measures can be taken to improve the quality control of building forgings:
a. Strengthen raw material procurement management: select alloy materials that meet the requirements to ensure that their chemical composition, mechanical properties and other indicators meet the relevant standards. At the same time, strengthen the warehousing inspection of raw materials to prevent unqualified materials from entering the production link.
b. Strengthen production process supervision: formulate strict process and operating procedures to ensure that each link in the production process meets the standard requirements. Strengthen the maintenance and maintenance of production equipment to ensure stable and reliable operation of equipment.
c. Implementation of quality testing and evaluation: comprehensive quality testing of forgings, including chemical composition, mechanical properties, dimensional accuracy, surface quality, etc. At the same time, establish a sound quality assessment system to trace and rectify unqualified forgings.
d. Improve the quality of employees: strengthen the training and education of employees, improve the skill level and quality awareness of employees. Establish an incentive mechanism to encourage employees to actively participate in quality improvement activities.
Iii. Summary and prospect
Building forgings have a wide application prospect in the construction industry, and their mechanical properties and quality control have an important impact on the safety and durability of buildings. In order to improve the performance and quality of building forgings, we must pay attention to many aspects such as raw materials, forging process, production process and staff quality. With the continuous development of science and technology, building forgings will face more challenges and opportunities in the future. Driven by the trend of new urbanization construction and green building, building forgings will develop in the direction of high strength, light quality, energy saving and environmental protection. At the same time, with the promotion and application of intelligent manufacturing technology, building forging will pay more attention to the development of digital, intelligent, automation and other technologies to improve production efficiency and quality stability. Therefore, the research and development of building forgings in the future should pay more attention to scientific and technological innovation and industrial upgrading to adapt to the changing market demand and industry development trends.
