摘要
本文实验研究了三种添加剂对Hoganas法还原速度的影响，结果表明：在铁精矿还原率为90％之前时，NaCl对还原过程有较大的催化作用，其合适的加入量为煤量的10％．Hoganas法还原过程的限制性环节含有不包括氧传递步骤在内的碳的气化反应过程．
The effect of three kinds of additives on the reduction rate of Honganas process are investigated through experiment. The experimental results shows that the NaCl have larger effect of catalysis on the reduction rate before having the reduction degree of 90%. The proper additive content of NaCl is 10% of coal amount. The rate-controlling step of reduction contain,the but step of oxygen transfer in are not included.
