利用罐式法直接还原原理在试验室进行了氧化铁鳞制取直接还原铁的研究。结果表明 ,当反应温度Z1≥ 12 0 0℃ ,时间Z2 ≥ 7.2h ,配煤比Z3≥ 30 % ,可确保还原产品的金属化率Y≥ 90 %
Using the method of direct reduction of tank method in the laboratory for the study of direct reduction iron oxide scale. The results show that when the reaction temperature Z1≥12 0 0 ℃, time Z2≥7.2h and the coal blending ratio Z3≥30%, the metallization rate of the reduced product can be ensured to be Y≥90%
