一、问题提出 从1989年8月份开始,鞍钢出现了生铁严重不足的情况,威胁着我厂平炉炼钢生产。在这种情况厂,我们得知内蒙某矿出产一种隐晶体石墨(我们称为类石墨),可以代替生铁配炭。经过实验,进行了大量应用,缓解了生铁供应不足,保证了平炉炼钢连续生产,降低了钢的成本,获得了明显的经济效益。 I. Problematic Proposal Since August 1989, Ansteel has experienced a serious shortage of pig iron, threatening the production of open hearth steelmaking in our company. In this case, we learned that a mine in Inner Mongolia produces a kind of cryptocrystalline graphite (we call it graphite-like) that can replace pig iron and charcoal. Through experiments, a large number of applications were carried out, which alleviated the shortage of pig iron supply, ensured continuous production of open hearth steelmaking, reduced the cost of steel, and achieved significant economic benefits.
