根据高炉物料平衡和区域热平衡理论 ,参照高炉富氧喷煤和使用金属化炉料的冶炼结果 ,计算了炉料金属化率对富氧喷煤率、焦比和产量的影响。结果表明 :1炉料金属化率达到 40 %后 ,高炉不能富氧操作 ;2较低的炉料金属化率与富氧喷煤相结合 ,能够获得更大的喷煤比和更高的产量 ;3使用金属化率较高的炉料 ,能够比富氧喷煤达到更低的焦比 According to blast furnace material balance and regional heat balance theory, with reference to the results of blast furnace oxygen-enriched coal injection and metallurgical furnace metallurgy, the effects of charge metallization ratio on oxygen-rich coal injection rate, coke ratio and yield were calculated. The results show that: 1 blast furnace metallization rate reached 40%, the blast furnace can not be oxygen-rich operation; 2 lower charge metallization rate and oxygen-rich coal injection, can get a larger coal injection ratio and higher output; With higher metallization charge, a lower coke ratio than oxygen-rich coal can be achieved
