Heat treatment equipment has many advantages such as fast heating speed, energy conservation, no oxidation and decarburization, no environmental pollution and high production efficiency. These advantages are widely recognized by heat treatment workers, so it has developed rapidly in the past decade or so. Of course, this actual demand has also greatly promoted the development and technological improvement of domestic induction heat treatment equipment. Take China FAW in Changchun as an example. The company has nearly 100 induction heat treatment devices, among which 50 have been newly added or updated in the past decade, almost all of which are silicon-controlled rectifier medium frequency equipment and IGBT super audio frequency equipment. Now, the weight of induction heat treatment parts for FAW's medium-sized trucks has reached 291.3 kilograms, accounting for 52% of all heat treatment parts. Heat treatment has truly held up half the sky of heat treatment.

  Nationwide, controlled atmosphere furnaces and vacuum furnaces account for less than 5% of heat treatment equipment in total. Some equipment with high labor intensity, serious pollution and high energy consumption still make up a considerable number. The energy sources for the industrial production of heat treatment equipment are mainly coal and oil. The expansion of industrial production scale worldwide has led to an increasingly severe energy crisis, causing a significant increase in energy prices that have exceeded the affordability of various countries. Meanwhile, industrial production inevitably leads to the deterioration of environmental pollution problems. The adverse consequences caused by the discharge of industrial waste are affecting the normal production and life of human beings. To alleviate the above-mentioned problems, all countries are committed to the development and application of new alternative energy materials. Currently, the most widely recognized new alternative energy is undoubtedly bioenergy. Bioenergy has a low cost and its raw materials are readily available, making it the best choice for energy-saving industrial furnaces.

  The reliability of heat treatment equipment and processes depends on the reliability of mechanical actions, electrical components, instruments and meters, sensors, and the entire system. This issue has long been a bottleneck hindering the development of heat treatment technology and equipment in our country. Nowadays, control components and their control systems have achieved significant development. Market supply and technical services have become increasingly convenient. High-quality foreign products can be purchased domestically, and domestic products have also made considerable progress. Users can choose the grade of products based on their actual needs. Since the quenching machine tools entered the Chinese market, authoritative figures in the domestic heat treatment field have comprehensively analyzed and explained based on the current domestic economic conditions, transportation, market areas and opportunity conditions, etc. Under the current general situation, the development of the domestic mold heat treatment equipment manufacturing industry has shown obvious differences between inland and coastal areas. Especially under the influence of the world economic crisis in recent years, many mold manufacturing industries have been quietly upgrading and transforming. During this period, significant regional differences have emerged.

  The improvement of the quality of heat treatment equipment products and the production process should involve the enhancement of the quality, reliability and control technology of heat treatment equipment, as well as the quality reproducibility and performance of heat treatment products. The realization of high-standard requirements for heat treatment equipment is an important prerequisite for the quality dispersion of heat treatment products, such as performance and deformation, to tend towards zero. Foreign heat treatment equipment comprehensively controls the process parameters of the entire heat treatment process and is developing towards automation, integration, flexibility and intelligence. In China, controlled atmosphere heat treatment, which was applied in the 1960s, is still only used in some large enterprises and a few specialized factories.
