武钢自1976年开始了“○七”工程的建设,新建了第二炼钢厂的转炉连铸工程和热轧、冷轧、硅钢片厂等新的轧钢系统工程。随着钢产量的急剧增长,对耐火材料的需要量也成倍增加,同时对耐火材料的品种质量提出了新的更高的要求。为了满足生产需要,武钢本着立足于国内指导思想,提出挖掘武钢 Since 1976, WISCO started the construction of “○ 7” project and built a new furnace continuous casting project and a new rolling system project such as hot rolling, cold rolling and silicon steel sheet factory in the second steelworks. With the rapid growth of steel production, the demand for refractory materials also multiplied, while the quality of refractory varieties put forward new and higher requirements. In order to meet production needs, Wuhan Iron and Steel based on the domestic guiding ideology, proposed mining WISCO
