Nationwide, controlled atmosphere furnaces and vacuum furnaces total less than 5% of heat treatment equipment, and some labor-intensive, heavily polluted and energy-intensive equipment still accounts for a large number. The energy sources for industrial production of heat treatment equipment are mainly coal and oil. The expansion of the industrial production scale worldwide has made the energy crisis increasingly serious, causing energy prices to rise significantly beyond the tolerance of countries. At the same time, industrial production It will inevitably cause environmental pollution problems to worsen, and the bad effects caused by the discharge of industrial waste are affecting the normal production and life of human beings. In order to alleviate the above problems, all countries are committed to the development and application of new alternative energy materials. The currently accepted new alternative energy is non-bioenergy. The cost of bioenergy is low, and raw materials are everywhere. They are energy-saving industrial furnaces. best choice.
The reliability of heat treatment equipment and process depends on the reliability of mechanical actions, electrical components, instruments, sensors, and the entire system. This problem has been a bottleneck that has plagued the level of heat treatment technology and equipment in China. Nowadays, the control components and their control systems have been greatly developed, and market supply and technical services are becoming more and more convenient. High-quality products from abroad can be bought at home, and domestic products have also made considerable progress. Select the grade of the product according to the actual needs. Since the beginning of quenching machine tools entering the Chinese market, authoritative figures in the field of domestic heat treatment have explained through comprehensive analysis based on the current domestic economic conditions, transportation, market areas, and opportunities: In the current situation, the development of the domestic mold heat treatment equipment manufacturing industry has There are obvious differences between inland and coastal areas. Especially under the influence of the world economic crisis in these years, many mold manufacturing industries have been quietly undergoing upgrading and transformation. During this time, great regional differences have occurred.
The improvement of the quality of heat treatment equipment products and the precise production process involve the improvement of the quality, reliability and control technology of heat treatment equipment, as well as the improvement of quality reproducibility and product performance of heat treatment products. The realization of the high index requirements of heat treatment equipment is an important premise that the quality dispersion and other quality dispersion of heat treatment products tend to be zero. The foreign heat treatment equipment has comprehensive control of the process parameters of the entire heat treatment process, and is developing in the direction of automation, integration, flexibility and intelligence. In China, the controlled atmosphere heat treatment applied in the 1960s is only used in some large enterprises and a few professional factories.
Induction heat treatment equipment has many advantages such as fast heating speed, energy saving, non-oxidation and decarbonization, no pollution to the environment, and high production efficiency. These advantages are widely recognized by heat treatment workers, so they have developed rapidly in the past ten years. Of course, this actual demand has also greatly promoted the development and technological upgrading of domestic induction heat treatment equipment. Take Changchun's China FAW as an example. The company has more than 100 induction heat treatment equipment, of which 50 have been added or updated in the past ten years, almost all of which are thyristor intermediate frequency equipment and IGBT super audio equipment. Now the weight of induction heat-treated parts of FAW's medium-duty trucks reaches 291.3kg, which accounts for 52% of all heat-treated parts. Induction heat treatment has really stood up to half a day of heat treatment.
