可控气氛热处理的普遍应用是近代热处理技术发展的标志之一。这项技术在国外工业发达的国家中已被广泛采用;在我同实行发展国民经济的第四个五年计划前夕,一机部在武汉召开的制订我国热处理发展规划座谈会上,确定把推广可控气氛热处理列为机械工业热处理第四个五年计划的第一个项目。它的优点主要有以下几方面: 1.可减少或避免金属在热处理加热时的氧化烧损,节约大量金属。例如,在汽车、拖拉机制造行业中,热处理造成的氧化烧损占热处理
The universal application of controlled atmosphere heat treatment is one of the hallmarks of the development of modern heat treatment technology. This technology has been widely adopted in developed industrial countries abroad. On the eve of my fourth five-year plan for the development of national economy, a machine-building department held a seminar on formulating the development plan for heat treatment in Wuhan to determine the promotion Controlled atmosphere heat treatment is listed as the first project of the fourth five-year plan of mechanical industrial heat treatment. Its advantages are mainly the following aspects: 1. To reduce or avoid oxidation of metal heat treatment in the heat loss, saving a lot of metal. For example, in the automobile and tractor manufacturing industries, the heat treatment causes the oxidation loss and heat loss
