可控气氛热处理是我国重点推广的先进技术之一。采用可控气氛热处理工艺,机械零件不再在加热过程中氧化烧损,能节约大量金属;使零件光亮、美观,保证尺寸精度;热处理后无需清理,节约工时;可避免脱碳,提高材料的性能,延长零件使用寿命;还可控制钢表面碳浓度的渗碳和碳氮共渗,严格控制质量;已脱碳的钢材及零件能在可控气氛中施行复碳,所以它是热处理技术上的一大革新。
Controlled atmosphere heat treatment is one of the key technologies promoted in China. The use of controlled atmosphere heat treatment process, the mechanical parts are no longer oxidative burning in the heating process, which can save a lot of metal; make the parts bright, beautiful, to ensure dimensional accuracy; no need to clean up after heat treatment, saving time; to avoid decarburization and improve the material Performance, extend the life of parts; also can control the carburizing and carbonitriding of carbon concentration on the surface of steel, strict quality control; decarburized steel and parts can be implemented in a controlled atmosphere carbon, so it is heat treatment technology A major innovation.
