In modern industry, gate valves are widely used in multiple fields such as petroleum, natural gas, chemical industry, and power generation to control the flow of fluids. The performance and reliability of gate valvesare directly related to the safety and stability of the system. As an advanced manufacturing technology, precision forging process can significantly improve the mechanical properties and dimensional accuracy of gate valve valves, reduce internal defects, and extend service life. Therefore, optimizing the precision forging process and strengthening quality control are of great significance for improving the overall performance of gate valve valves.
Precision forging is an advanced manufacturing technology that precisely controls the metal deformation process and can produce high-precision and high-performance forgings with a lower machining allowance. Compared with traditional forging processes, precision forging has the following advantages:
• High dimensional accuracy: It can significantly reduce the machining allowance and lower the subsequent machining cost.
• Excellent mechanical properties: By optimizing the deformation process, a fine grain structure can be obtained to improve the strength and toughness of the material.
•Reduction of internal defects:By precisely controlling forging parameters, internal cracks, pores and other defects can be effectively reduced.
Raw material inspection
The quality of raw materials directly affects the performance of the final product. Conduct strict chemical composition analysis and mechanical property testing on raw materials to ensure that they meet standard requirements. For example, conduct chemical composition analysis on F91 steel to ensure that the content of elements such as chromium and molybdenum meets the design requirements.
Production process monitoring
During the forging process, monitor process parameters in real time, such as heating temperature, forging ratio, and deformation speed, to ensure the stability and consistency of the process. For example, install temperature sensors and pressure sensors to monitor temperature and pressure changes in the forging process in real time.
Product inspection
Adopt advanced detection technologies, such as X-ray detection, ultrasonic detection, and three-coordinate measurement, to conduct comprehensive inspection on finished products to ensure that castings are defect-free. For example, X-ray detection can effectively detect porosity and inclusion defects inside castings.
