With the increasing application of vacuum technology, it covers an aerospace and military industry, photovoltaic power generation and other fields, and is an indispensable technology for industrial systems. At present, vacuum technology has been valued by countries all over the world, and vacuum equipment, technology, materials and accessories have broad market prospects. China's vacuum equipment industry is growing at an annual rate of about 20%. In the support of national major project projects, the domestic vacuum technology industry can no longer meet market requirements in quality. Below we give a brief overview of the needs of vacuum technology in three major industries:
Metallurgical industry: Vacuum technologies used in the metallurgical industry include vacuum treatment of molten steel, vacuum melting, vacuum induction melting, induction shell melting, vacuum arc remelting, etc. Among them, vacuum steel treatment is an important aspect of the metallurgical industry. This technology is mainly used in the atomic energy industry, space technology, marine drilling technology, gas engine technology, automotive industry, aircraft manufacturing, high-speed trains and other high-tech industries to control and process certain elements in steel. The life and reliability of materials are placing increasing demands. At present, various application industries have modern vacuum processing equipment, which greatly reduces the content of nitrogen, hydrogen, oxygen and other impurities in the steel, and the treatment level is also continuously improved. The United States, Japan, Germany and other countries have adopted this technology as a national standard, and adopted 100% vacuum degassing treatment for their bearing steel, electrical steel and high-quality large forgings to complete the basic requirements of the modern steel industry.
Electronics and microelectronics industry: Microelectronics requires smaller and smaller electronic components and circuits, and higher integration requirements. This is inseparable from the application of vacuum technology, especially the micro-machining technology of VLSI. The formation of geometric structure, ultra-thin layer growth technology and particle beam injection technology all require high-quality, clean vacuum environment. Dependence on vacuum technology and equipment. At present, about 60% of the sales of vacuum manufacturers in Japan are for the electronics industry, and today about three-quarters of VLSI's processes require vacuum conditions.
Machinery manufacturing industry: This is an industry that is highly driven and has a wide range of functions. At present, the gloom of the European debt crisis has not dissipated. Countries have actively adopted the machinery manufacturing industry as the focus of boosting the economy. Its technical applications are generally concentrated in traditional fields such as vacuum heat treatment, vacuum brazing, vacuum coating tools. Vacuum heat treatment refers to a new heat treatment technology that combines vacuum technology with heat treatment technology. Its handling of tools, molds and precision couplings can improve the service life, accelerate the adsorption and reaction process of chemical heat treatment. In addition, its own flexible operation and pollution-free features have become common treatments in the industry.
