Production Practice of Increasing the Consumption of Steel Blast Furnace
Compared with sintering,ball ore and other clinker have innate cost advantages,but its physical,chemical and metallurgical properties are inferior to those of clinker,and a large proportion of them directly into blast furnace smelting will bring adverse effects on the melting properties of furnace material.Therefore,this paper introduces the quality of several blocks used by new steel,and emphatically introduces the raw material management and production operation adjustment mode in the higher proportion of blocks.Combined with the pre-process and equipment level of the new steel,the cost performance of lump ore,sinter ore and pellets is calculated according to the inclusive index,and through fine management and careful operation,the dynamic optimization of the furnace charge structure is realized to maintain the optimal cost of molten iron.
