| 摘 要： | 石家庄钢铁公司高炉的碱金属(K_2O Na_2O)负荷较高,为5．25～5．5kg/tFe。其中由烧结矿带入的碱金属占碱金属负荷的70％左右,球团矿和焦炭各占碱金属负荷的10％左右,其它炉料带入量较少。石钢高炉总排碱率为73％～79％,其中炉渣排碱率为68％～77％,炉顶煤气排碱率为5％左右。石钢高炉蓄积率保持在0．227～0．282kg/Fe·h之间,高炉处于蓄积期,且蓄积率较高。所以,建议石钢高炉的碱金属负荷临界值选取4．0kg/tFe。

| Abstract: | The alkali metals loads of ShiGang blast furnace were high,between 5.2 kg/tFe to 5.5kg/tFe.Among it, the alkali metals in the sinter was 69%,either pellet or coke was about 10%,other charges were litde.The total re- moving alkali rate of ShiGang BFs were 73% to 79%.Among it,removing alkali metals rate of slag is 68% to 77% and top gas is 5%.The accumulation rates of the alkail metals of ShiGang BFs were 0.22kg/tFe.h to 0.28kg/tFe. h and BFs were in accumulation age,Thus it suggested that ShiGang critical alkail metals load is 4.0kg/tFe. |
