安阳钢厂在生产无缝钢管时用的冷拔模原是采用45钢经渗碳淬火或液体氰化的,由于寿命低,满足不了生产需要,而且原材料消耗大、加工工时多。为提高模具使用寿命,1973年我们开始协作,组成了三结合小组,对模具的渗硼工艺进行了反复实践,渗硼工艺逐步完善和提高,在冷拔模上的应用也有明显效果, 。一、盐浴配方及配制我们分析和试验了各种配方的性能以后,从渗硼能力、盐浴流动性、成
Anyang Iron and Steel Mill in the production of seamless steel pipe cold drawing die when the original is 45 steel by carburizing quenching or liquid cyanide, due to low life, can not meet the production needs, and raw material consumption, processing time and more. In order to improve the service life of the mold, we started to collaborate in 1973 to form a three-in-a-small group. The boronizing process of the mold was repeatedly practiced. The boronizing process was gradually improved and improved. The application on the cold drawing mold also had obvious effects. First, salt bath formula and preparation We analyzed and tested the performance of various formulations, from boronizing ability, salt bath liquidity, into
