安钢1号高炉为降低生铁成本,采用了“提块降球”措施,即在高炉炉料结构中,提高块矿的比例,并相应地降低球团矿的比例。经过近50天的实际生产实践,取得了较好的效果。生产实践表明,“提块降球”措施的降本效果,必须由高炉炉况的稳定顺行作保障,并且是原料成本的降低额,要大于燃料成本升高额,或原料成本和燃料成本均是降低的。
In order to reduce the cost of pig iron, Angang’s No. 1 blast furnace adopted the method of “lifting lugs and dropping balls”, that is, increasing the proportion of lump ore in the blast furnace charge structure and reducing the proportion of pellets accordingly. After nearly 50 days of actual production practice, and achieved good results. Production practice shows that the lowering effect of the “lifting off the ball” measures must be guaranteed by the stable and straightforward operation of the blast furnace and is a reduction in the cost of raw materials, which is greater than the increase in fuel costs or the cost of raw materials and Fuel costs are reduced.
