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，但幅度不大
The temperature of 1450 ℃; CO gas reduction FetO-TiO2, FetO-V2O5PetO-CaF2 and FetO-Al2O3 four binary slag test, calculated by the CO2 infrared analyzer CO2 content of the outlet gas calculated the reduction reaction rate. The results show that the reaction rate of FetO-TiO2 slag decreases with the increase of TiO2 content; the reaction rate of FetO-V2O5 slag increases with the increase of V2O5 content; Al 2 O 3 has little effect on the reaction rate of FetO-Al 2 O 3; The reaction rate of FetO-CaF2 slag system has an increase effect, but the magnitude is not big
