摘　　要：介绍了因焦炭价格持续走高,而神木兰炭具有高固定碳、高反应性、高比电阻、低灰分、低三氧化二铝、低硫、低磷的特点,焦炭与神木兰炭的价差逐步拉大。为了降低还原剂使用成本,搭配一定比例的神木兰炭生产锰硅合金,取得了稳定炉况、提高锰回收率、降低电耗及生产成本的效果。Due to the continuous rise of coke price,the price difference between coke and Shenmu semi-coke has gradually widened.Shenmu semi-coke has the characteristics of high fixed carbon,high reactivity,high specific resistance,low ash,low aluminum oxide,low sulfur and low phosphorus.In order to reduce the reductant cost,a percentage of Shenmu semi-coke is matched to produce ferromanganese-silicon,which has achieved the effects of stabilizing furnace condition,improving manganese recovery rate,reducing power consumption and reducing production cost.
