Heat treatment will drive the rapid development of Chinese heat treatment industry

With the continuous development of heavy industries such as parts and machinery manufacturing, heat treatment plays an important supporting role in the revitalization and development of China's machinery manufacturing industry. Development provides a broad space for development, and the industry has broad development prospects. In view of the development status of China's heat treatment equipment industry, it is necessary to enhance the overall level of China's heat treatment industry. First, make full use of industry information platforms, promote new technologies, and guide enterprise innovation. For example, the recently launched “China Heat Treatment” 3G platform can be used as an information platform for technology sharing in the heat treatment industry; Provide support for emission reduction; again, vigorously strengthen the training infrastructure to provide talent protection for the development of China's heat treatment industry; finally, give full play to the role of the expert committee as a think tank and carefully organize the recommended infrastructure projects. According to China Industry Insight, China is a major energy consumer, and the machinery manufacturing industry is an important part of it.
China's heat treatment equipment industry is developing rapidly and has broad prospects. However, in the face of the rapid development of new products and the replacement of old products, although the production equipment of China's heat treatment enterprises can meet the production needs of the machinery industry, there are well-known brands in the heat treatment industry The "special, precise, special" enterprise group has not yet formed, and there is a shortage of professional and technical personnel, and the promotion and application of new technologies is difficult; less than 10% of the entire industry can achieve precision controlled automation and digital production equipment. Obsolete old equipment, relying on the "skills" operation of "master", product quality dispersion is very large, it is difficult to fully guarantee the stable improvement of product quality level of mechanical basic parts. For enterprises, they should vigorously improve their technological innovation capability, improve their informatization level, constantly enrich the practical process database of heat treatment, use limited expert systems to provide technical support for small and medium-sized heat treatment enterprises, and guide enterprises to develop in the future direction of energy-saving and material-saving heat .
Metal materials are one of the most important materials for human development. No matter which era, metal materials play a huge role in people's lives. Metal materials have the characteristics of high toughness, high hardness and strength according to their characteristics, and metal materials are easy to obtain, and many metals are easy to make. With the development and promotion of modern metal technology and the development of science and technology, metal materials have obvious cost-effective advantages and broad prospects for development in the fields of mechanical manufacturing, defense, industry, agriculture, electronic information and other industries. The purpose of ordinary heat treatment is to improve the structure of the metal, adjust the strength, hardness, toughness, improve the processing performance of the metal, and do not change the chemical composition of the metal. The main processes are annealing, normalizing, quenching and tempering. Annealing is a heat treatment process that heats the steel to the required value of the process, keeps it warm for a certain period of time, and then slowly cools to obtain a balanced state. The purpose of annealing is mainly to reduce the hardness, which is beneficial to the mechanical performance of the metal; refine the grain, improve the plasticity and toughness; and eliminate the internal stress.
The traditional heating sources of metal heat treatment equipment mainly include fuel heating sources and electric heating sources. In recent years, a new high-energy-rate heating source has been born, such as laser beam heating sources and electron beam heating sources. It is mainly used to directionally treat the surface of the workpiece Applying extremely high energy density heating, this method can quickly raise the surface temperature of the workpiece, so that in a very short time, the temperature of the surface layer of the workpiece to be processed is raised above the phase transition temperature or molten state, and then let The workpiece cools itself until its surface hardens or solidifies, eventually causing some of its surface characteristics to change. This high-energy-rate heat treatment can reduce the deformation of the workpiece, make the workpiece obtain special organizational properties and surface conditions, improve the wear resistance and corrosion resistance of the workpiece surface, extend the service life of the workpiece, and have a great effect in improving economic benefits.
