在国内外热处理生产中,尽管研制和应用的新工艺不少,但大量使用的还是常规工艺(主要指淬火、回火、正火、退火、渗碳、渗氮),其优劣对产品的质量、经济效益起着极为重要的作用,也是体现热处理生产技术水平的主要标志。长期以来,我国的常规工艺进展不大,在合理性、准确性等方面都存在着一定的问题。有的缺乏理论与实验依据,有的潜力还很大;即使工艺验证工作做得比较好的企业,也因产品更新换代等原因,其常规工艺也有不相适应之处,因而必须对常规工艺的优化与发展进行工作。国外,对热处理工艺与设备总的要求可以概括为安全性、可靠性和经济性,这也是热处理发展的总的趋势,对我国热处理的发展也很有参考价值。常规工艺的优化与发展,应以这“三性”为总的要求,并以提高产品零件的性能、寿命,运行可靠,节约能源和材料,缩短生产周期,降低成本,防止污染等为具体目标。下面谈谈常规工艺今后的展 In the heat treatment at home and abroad, despite the development and application of many new technologies, but the extensive use of conventional technology (mainly quenching, tempering, normalizing, annealing, carburizing, nitriding), the advantages and disadvantages of the product Quality, economic benefits play an extremely important role, but also reflect the level of heat treatment technology, the main sign. For a long time, the progress of conventional technology in our country is not big, and there are some problems in rationality and accuracy. Some lack of theoretical and experimental basis, and some great potential; even if the process validation work done better business, but also because of product replacement and other reasons, the conventional process also has incompatible with the Department, which must be conventional technology Optimization and development work. Abroad, the general requirements of the heat treatment process and equipment can be summarized as safety, reliability and economy, which is also the general trend of the development of heat treatment, the development of heat treatment in our country is also of great reference value. The optimization and development of the conventional process should be based on the overall requirements of the “three attributes” and to improve the performance of parts and components, life expectancy, reliable operation, energy conservation and materials, shorten the production cycle, reduce costs, prevent pollution, etc. specific goals. Here to talk about the future of conventional technology exhibition
