利用焦炉煤气还原球团矿的研究

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 a-chieved 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 .Tem-perature of gas exiting would descend 15 ℃with temperature of sponge iron raising each 50 ℃.Tem-perature of shaft furnace did not much affect temperature of gas exiting .
