本刊1952第2期与第3期曾先后刊载「液体孕育作用」和「不在炉外加孕育剂熔制高级铸铁的方法」两篇译文。里面详尽的介绍了苏联熔制孕育铸铁的两种先进经验,目前国内很多工厂有的已经采用,有的正在研究试制,为熔制孕育铸铁开辟了一条新的道路。本文系就上述两种方法加以补充,设备简单,技术操作上也易於控制,特为刊出,以供参考采用。
Our journal No. 2 and No. 3 of 1952 have successively published two translations of “liquid inoculation” and “non-furnace plus inoculant melting high grade cast iron”. Which introduced in detail the two advanced experiences of the Soviet Union in the melting of pregnant cast iron. At present, many factories in China have adopted some of them and some are studying and trial-forming to open up a new road for melting and nurturing cast iron. This article is to supplement the above two methods, the equipment is simple, technical operation is also easy to control, especially published for reference.
