Production Practice of Reducing Coke Ratio of No.10 3200 m3 Blast Furnace in Ansteel
In allusion to the problem of high coke ratio index of a blast furnace(BF),some measures such as improving the quality of raw materials and raw fuels,increasing the ratio of coal,ensuring a suitable type of furnaces,optimizing the charging system and improving the activity of hearth were proposed.After these measures were put into practice,the coke ratio of BF was reduced by 16 kg/t,the comprehensive coke ratio was reduced by 18 kg/t,and the output was increased by 360 t/d.Therefore,the BF was in steady and smooth operation for a long period with good results.
