摘　　要：以石人沟矿为原料,石油焦为还原剂,根据正交实验原理,在盖碳敞焰加热条件下,进行了直接还原的实验研究.通过研究获得了海绵铁生产工艺的合理操作参数.实验结果同时也表明,利用石人沟矿可以生产出全铁和金属化率均大于90％的海绵铁.Using Shirengou ore as raw material, pitch coke as reducing agent, according to the orthogonal experimental theory a experimental study of direct reduction was performed with coke-cover under the condition of open-firing atmosphere. The rational operating parameters of DRI production were obtained. The experimental results also show that DRI product can be produced with Shirengou Ore.
