摘　　要：为解决长期以来烧结矿粒度波动对高炉生产的影响,通过对槽下筛子进行改造,使焦丁和矿丁分级入炉,实现焦丁使用量45kg/t.Fe、矿丁使用量110kg/t.Fe,生产成本降低,高炉顺行未受影响,取得良好的生产实践效果。In order to solve the influence of sinter size fluctuation on blast furnace production for a long time,through reforming the sieve under the sinter trough,nut coke and small sinter are classified into the furnace,and the con sumption of nut coke is 45 kg/t.Fe,the consumption of small sinter is 110 kg/tFe,the production cost is reduced,the blast furnace goes forward unaffected,and good production practice results are achieved.

关 键 词：焦丁 矿丁 钒钛磁铁矿
