自从全民大办钢铁工业以来,土铁产量日日增加,洋铁必须供应重点钢厂,铸造车间如何利用土铁来作机器铸件,即成为当前生产中迫切需要解决的问题,土铁中一般均是碳、硅、锰低、硫高,硫一般平均在l%,也有高达3~5%的.为广使白口变为灰口,使土铁成器,我们从九月份开始在北京第二通用机械厂生产上用的冲天炉进行了一系列实验,并获得初步成功,到现在作成

Since the People’s Republic of China has been engaged in the steel industry, the production of soil iron has been increasing day by day, and the foreign iron and steel must supply the key steel mills. How to use soil iron for the casting of machinery in the foundry has become an urgent problem to be solved in current production. Carbon, silicon, manganese, sulfur, sulfur generally average l%, but also up to 3 ~ 5%. To make the white mouth into a gray mouth, make the soil into a device, we start from September in Beijing second General Machinery Plant production with a cupola conducted a series of experiments, and achieved initial success, to make now
