In the smelting of ferro—manganese in blast furnace, the variation of manganese recovery rate is so large that it ranges from 60—90%. The ore ration depends on the avereage manganese content of feed ore and manganese recovery. The consumption of manganese ore can be reduced by 44.6kg/t,coke ratio by 7.7kg/t,the cost by 25.53¥(Renminbi),the production can increased by 1.57% and the quality of product can be improved when the manganese recovery is increased by 1%.

In the smelting of ferro—manganese in blast furnace, the variation of manganese recovery rate is so large that it ranges from 60—90%. The ore ration depends on the avereage manganese content of feed ore and manganese recovery. The consumption of manganese ore can be reduced by 44.6kg/t,coke ratio by 7.7kg/t,the cost by 25.53¥(Renminbi),the production can increased by 1.57% and the quality of product can be improved when the manganese recovery is increased by 1%. Manganese's chemical loss in slag is directly proportional to the quantity of slag and MnO in slag;lost manganese is as 16.80% as the total of manganese quantity which is fed into the furnace,accounting for 60.27% of the total lost quantity. Another loss is one from top of the furnace. The operation of high CaO/SiO_2. MgO slag is an alternative process for reducing MnO in slag.

高炉冶炼锰铁时,锰的回收率波动很大,在60—90%范围,矿比取决于入炉矿的平均含锰量和锰的回收率。每提高锰回收率一度,可降低锰矿消耗44.6kg/t,降低焦比27.7kg/t,增产1.57%,降低成本25.53元/t,并可提高产品质量。锰在渣中的化学损失与渣量和渣中MnO成正比,流失锰为入炉总锰量的16.8%,占流失总量的60.27%,为炉顶损失。采用高MgO渣操作,是降低渣中MnO的有效措施。已使MnO含量降至4—5%,Mn回收率已达85%。

According to practice of high top pressure for blast furnace at home and abroad,this technology is proposed for Fe-Mn blast furnace operation by taking an account of characteristics in Fe-Mn smelting and the existent production conditions at Xinyu I & S Complex.

By means of a mathematic model eqaution established under given process conditions of ferromanganese blast furnace,a procedure for computing the theo- retical coke ratio of ferromanganese blast furnace had been found.This can be used as a base to evalute the operation standard of blast furnace ferromanganese production.Technological measures for reducing coke ratio are proposed.

通过锰铁高炉在一定冶炼条件下建立的数学模型方程式,找出冶炼锰铁理论焦比的计算方法,从而有了评价高炉锰铁冶炼操作水平的基准。提出了锰铁高炉降低焦比的技术改造方向。
