随着我国铸石工业的迅猛发展,作为铸石生产的结晶促进剂——铬铁矿的用量越来越大。由于铬铁矿是一种重要物资,在目前还比较缺乏。因此,我们觉得寻找新的结晶促进剂以代替铬铁矿是铸石工业发展的重要课题。我厂遵照伟大领袖毛主席的教导,大搞科学实验,于1970年利用废料——冶金铬渣代替铬铁矿,试制成功铬渣辉绿岩铸石(下简称铬渣铸石),于1971年正式用于生产,较好地解决了铸石生产的结 With the rapid development of cast stone industry in our country, the amount of chromite ore used as crystallization accelerator in the production of cast stone is getting larger and larger. As chromite is an important material, it is still relatively scarce at present. Therefore, we think finding a new crystallization promoter instead of chromite is an important issue for the development of cast stone industry. I plant in accordance with the great leader Chairman Mao’s teachings, engage in scientific experiments, in 1970 the use of waste - metallurgical chromium slag instead of chromite, trial production of chromium slag diabase cast stone (hereinafter referred to chromium slag cast stone), in 1971 Years of formal use for the production, a better solution to the production of cast stone
