安钢2号高炉经济块矿生产实践与成本分析

降低成本是现在钢铁企业日益迫切的任务。安钢2号高炉通过使用1.55%经济块矿，综合冶炼工序成本降低3.81元/t,为安钢降低成本探索出一条新途径。经济块矿的使用效益不能仅仅考虑生铁成本变化情况，还要考虑生铁质量变化对炼钢工序成本的影响。高炉精心操作并保持稳定顺行是经济块矿效益发挥的保证。

Practice and cost analysis of proportioning economic lump ore of Angang No. 2 BF

Cost reduction is an urgent need for the steelmakers. With proportioning 1.55 % economic lump ore, An- gang No. 2 BF has cut the cost of 3.81 yuan per ton iron. It becomes one of the good methods to reduce cost for An- gang. When analyzing the benefit of economic lump ore, it should not only compare the cost of molten iron, but also consider the effect of hot metal quality on the cost of steelmaking process. The careful operation of BF and stable di- rect motion is the guarantee of the performance of the benefit of economic lump ore.
