摘　　要：温度为1450℃时；进行了CO气体还原FetO－TiO2、FetO－V2O5PetO－CaF2和FetO－Al2O3四个二元渣系的试验，根据CO2红外分析仪测定的出口气体中CO2含量计算了还原的反应速率．结果表明，FetO－TiO2渣系的反应速率随TiO2含量的增加而减小；FetO－V2O5渣系的反应速率随V2O5含量的增加而增加；Al203对FetO-Al2O3的反应速率影响不大；CaF2对FetO－CaF2渣系的反应速率有增加作用。The reduction rate of FetO with CO gas at 1450℃ was measured for FetO-TiO2, FetO-V2O5， FetO-CaF2 and FetO-Al2O3 molten binary slags contained in a pure iron crucible. The reduction rate was evaluated from measurement of CO2 evolution by an infrared gas analyzer. It was found that the reduction rate of FetO-TiO2 decreased with the increase of TiO2 content in this binary slag system; the rate of reduction in FetO-V2O5 system increased with the increase of V2O5 content in this slag system. The addition of CaF2 to liquid FetO increased the reduction rate slightly, and Al2O3 had no marked effect on the rate of FetO reduction.
