Chinese heat treatment equipment industry has achieved a series of gratifying results

In recent years, China's heat treatment equipment industry has achieved a series of gratifying achievements: in terms of quality management, technological transformation, degree of specialization and opening to the outside world, there have been some degrees of progress. The labor productivity of all employees in the industry has also improved significantly. From the data analysis of the survey of 843 heat treatment plants and sites last year, it is about 40% higher than the data surveyed in 1997. Induction heat treatment has many advantages such as fast heating speed, energy saving, non-oxidative decarburization, non-polluting environment and high production efficiency. These advantages are widely recognized by heat treatment workers, so they have developed rapidly in the past decade.
Induction heat treatment equipment has many advantages such as fast heating speed, energy saving, non-oxidative decarbonization, non-polluting 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 also greatly promotes the development and technological improvement of domestic induction heat treatment equipment. Heat treatment equipment is a process that has an important influence on product quality in the mechanical manufacturing process. In the face of the new situation, it is necessary to carefully analyze the requirements of the development of the machinery industry, and combine the development characteristics of the heat treatment industry to make necessary adjustments to the focus of the enterprise.
Exhaust gas, waste water, waste residue, dust, noise and electromagnetic radiation from the production of heat treatment equipment, if not paying attention, will pollute the work site and surrounding environment. Advanced heat treatment technology should first be a technology that does not pollute the environment. These include cleaning processes, cleaning equipment, cleaning materials, etc. Controlled atmosphere, vacuum and induction heat treatment with good shielding are typical cleaning processes widely used. Plasma heat treatment, low-pressure carburization, high-pressure gas quenching, laser electron beam strengthening, spray quenching, vacuum cleaning, etc. are all low pollution technologies. The change in shape and size of metal parts during heat treatment is inevitable. Excessive and uneven distortion will increase the processing allowance or make it scrapped. Automobile gearbox gears are generally not processed after heat treatment. Distortion will make them lose interchangeability or increase gaps and increase vehicle noise.
The improvement of the quality of heat treatment equipment products and the precise production process should involve the improvement of the quality, reliability and control technology of heat treatment equipment and the reproducibility of quality and performance of heat treatment products. The realization of the high index requirements of heat treatment equipment is an important prerequisite for the quality dispersion of heat treatment products such as performance and deformation to zero. Foreign heat treatment equipment has full control of the process parameters of the whole 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. Nationwide, controlled atmosphere furnaces and vacuum furnaces account for less than 5% of heat treatment equipment, and some equipment with high labor intensity, serious pollution, and high energy consumption still accounts for a large number.
