As an important part of the energy field, the safety and reliability of nuclear power equipment are crucial to ensuring global energy supply and nuclear security. As a key component in nuclear power equipment, the quality and performance control of forging is particularly critical in its manufacturing process. As an advanced metal forming technology, warm forging plays an important role in the forging of nuclear power equipment. This paper will discuss the safety and reliability of warm forging process in forging of nuclear power equipment, and introduce its related quality control measures.
Application of warm forging process in forging of nuclear power equipment
Forging material selection: Nuclear power equipment forgings usually require the use of high strength, high toughness and corrosion resistance materials. The warm forging process is suitable for a variety of metal materials, including stainless steel, alloy steel and nickel-based alloys. By precisely controlling the heating temperature and forging speed, the warm forging process can eliminate the internal defects of the material, refine the grain, and improve the mechanical properties and corrosion resistance of the material.
Die design and manufacturing: Die is the key tool in the warm forging process, and its design and manufacturing quality directly affect the forming quality and dimensional accuracy of the forging. In the forging of nuclear power equipment, the mold needs to have high precision, high rigidity and high wear resistance. By adopting advanced die design technology and manufacturing process, such as computer-aided design (CAD) and CNC machining technology, the manufacturing accuracy and service life of the die can be improved to ensure the dimensional accuracy and surface quality of the forging.
Forging process control: The warm forging process requires precise control of process parameters such as heating temperature, forging speed and cooling speed. Through the introduction of advanced sensors and control systems, real-time monitoring and control of parameters such as temperature, pressure and displacement during the forging process can ensure that the forging is formed under the best process conditions and avoid defects and cracks. In addition, the use of numerical simulation and simulation technology can predict and optimize the forging process, improve production efficiency and forging quality.
Safety and reliability assurance measures of warm forging process in forging of nuclear power equipment
Quality management system construction: The establishment of a sound quality management system is the basis for ensuring the safety and reliability of nuclear power equipment forgings. Through the introduction of international standards and industry norms, such as ISO 9001 quality management system and nuclear safety regulations, establish strict quality control procedures and inspection standards, and conduct comprehensive testing and evaluation of raw materials, semi-finished products and finished products to ensure product quality meets the requirements.
Non-destructive testing technology application: Non-destructive testing technology is an important means to evaluate the internal quality and performance of forging. Through the introduction of ultrasonic testing, magnetic particle testing, eddy current testing and other non-destructive testing methods, the forgings are comprehensively tested, and the existence and severity of internal defects and cracks are timely found and assessed to ensure product safety and reliability.
Continuous improvement and technological innovation: The warm forging process requires continuous technological improvement and innovation in the forging manufacturing of nuclear power equipment. Through the introduction of new materials, new processes and new technologies, optimize process parameters and mold design, improve production efficiency and forging quality. At the same time, we will strengthen cooperation and exchanges with scientific research institutions and universities to promote technological innovation and industrial upgrading.
Personnel training and skill upgrading: Warm forging process requires operators with rich experience and professional knowledge. Through strengthening personnel training and skill upgrading, improve the professional quality and safety awareness of operators to ensure that they can master the operating skills and quality control points of warm forging process.
The warm forging process plays an important role in the safety and reliability of the forging of nuclear power equipment. By optimizing material selection, mold design and manufacturing, forging process control and other measures, combined with quality management system construction, non-destructive testing technology application, continuous improvement and technological innovation, we can ensure that the safety and reliability of warm forging process in nuclear power equipment forging manufacturing reaches the highest level. In the future, with the continuous progress of science and technology and the constant change of market demand, the requirements for warm forging process will continue to increase. We should actively explore and practice new processes and materials to contribute to the safe and reliable operation of nuclear power equipment.
