摘要
介绍了转炉LT干法除尘系统及LT除尘灰的成分和特性。莱钢除尘灰利用有长流程和短流程两种方案,除尘灰被加工成金属副产品、回转窑精粉和除尘灰压球。使用除尘灰压球替代烧结矿用于转炉冶炼,取得很好的脱硫、脱磷效果,并且吨钢降低成本6.02元,实现了干法除尘灰全部回收利用,减轻了环境污染。
The converter LT system,and the composition and characteristics of LT dust were introduced.There are two schemes for the utilization of LT dust in Laiwu Steel:long process and short process.The LT dust is processed into metal by-products,rotary kiln fine powder and dust pressing ball.Use dust pressing ball to replace ore agglomerate for metallurgical furnace smelting,the phosphorus and sulfur in molten iron was removed efficiently.And the cost per ton of steel was reduced by 6.02 Yuan,the full recovery and utilization of LT dust was realized,environmental pollution was reduced.
