摘　　要：介绍了大然气在一汽热处理厂气体渗碳、碳氮共渗等工艺上的应用,天然气取代丙烷气做富化气不但可以提高零件的产品质量,而且可获得显著的经济效益。同时指出,采用天然气代替丙烷气做原料气是可行的,但在渗碳和碳氮共渗工艺上要进行调整。特别是应用于碳氮共渗方面,应添加少量催渗剂以提高炉内碳势,如西北大学开发的ＢＨ催渗剂。Applications of natural gas in gas carburizing process and nicarburizing process in the FAW Heat TreatmentPlant are introduced. Substituting natural gas for propane gas as enriched gas not only can improve quality of products, butalso can remarkably increase economic benefits. It is pointed out at the same time that it is feasible to substitute natural gasfor propane gas as raw gas, but the carburizing process and nicarburizing process shall be adjusted, especially for thenicarburizing process,a bit of energizing agent,such as BH energizing agent developed by the Northwest University, shall beadded to increase carbon potential in the furnace.
