介绍了保护气氛热处理工艺方法的确定过程,主要分析了在特殊热处理要求下由滴注式气氛转换成氮甲醇气氛;并通过理论计算确定炉内碳势。
The process of heat treatment of protective atmosphere was introduced. The atmosphere of dripped atmosphere was changed to nitromethanol under the special heat treatment requirement. The carbon potential in the furnace was determined by theoretical calculation.
