在熔炼金属材料时配用钢屑和铁屑,在我厂已有二十多年的历史。二十多年来已配用这种“双屑”117800吨,以代替废钢,节约价值约达800万元。实践证明,这是一项很有经济意义的技术措施。但是,配用“双屑”炼钢,给炉料管理、准备、配料工作和熔炼操作带来了一些困难,使推广这一技术措施受到了一定 In the smelting of metal materials with steel scrap and iron filings, in our plant has more than 20 years of history. Over the past 20 years, it has allocated 117,800 tons of such “double shavings” to replace scrap and save about 8 million yuan in value. Practice has proved that this is a very economical technical measures. However, the use of “double shaving” steelmaking poses some difficulties for charging management, preparation, ingredient work and smelting operations, which has given rise to the promotion of this technical measure
