我厂自从使用稀土碳氮共渗工艺代替渗碳工艺后,产品质量有了很大提高,各种消耗明显降低,经济效益十分显著。但是稀土碳氮共渗剂是外购的,调价后,其价格增加一倍多,而且共渗速度低,仅为0.17～0.18mm/h。这样,稀土碳氮共渗成本有些增加,为此,我们决定自制共渗剂。经过近三年试验及试生产,用自制的共渗剂,渗速可达0.20～0.25mm/h,不仅降低了材料消耗,还节约了电能,收到了明显的经济效益。 I plant since the use of rare earth carbonitriding technology instead of carburizing process, the product quality has been greatly improved, a variety of significant reduction in consumption, economic efficiency is very significant. However, rare earth carbonitriding agent is purchased, the price adjustment, the price more than doubled, and the low infiltration rate, only 0.17 ~ 0.18mm / h. In this way, the cost of rare earth carbonitriding some increase, therefore, we decided to make self-infiltrating agent. After nearly three years of trial and trial production, with homemade osmotic agent, the infiltration rate can reach 0.20 ~ 0.25mm / h, which not only reduces the material consumption, but also saves the electric energy and has received obvious economic benefits.
