摘　　要：净化后的焦炉煤气具有较强的还原性能,在温度1100℃、配氧量6%的条件下净化时,(CO+H2)%达到了93.6%。调整此时的焦炉煤气温度,通入竖炉内还原球团矿,在其他条件一定时,焦炉煤气温度每升高50℃,竖炉气体出口温度升高约45℃;出铁温度每升高50℃,气体温度下降约15℃;竖炉反应温度对气体出口温度影响不大。Coke oven gas has excellent reducing property after purification. Content of CO and H2 achieved 93. 6 % after purification when temperature 1100 ℃,oxygen 6 %. To adjust the temperature of coke oven gas and reduce pellets of shaft furnace,the temperature of shaft furnace gas exiting would raise 45 ℃ with the temperature of coke oven gas raising each 50 ℃ under other given condition. Temperature of gas exiting would descend 15 ℃ with temperature of sponge iron raising each 50 ℃. Temperature of shaft furnace did not much affect temperature of gas exiting.
