高硅低铁的球磨吐块生产锰硅合金工业试验

INDUSTRIAL TEST OF PRODUCING FERROMANGANESE-SILICON WITH HIGH SILICON AND LOW IRON DIFFICULT-TO-GRIND ORE FROM THE MILLS

高硅低铁的球磨吐块为致密难磨的铁矿石,将其作为辅料进行冶炼锰硅合金工业试验,生产顺行,可减少原料中高价含铁锰矿的用量,降低生产成本,取得了较好效果。为降低锰硅合金成本、利用球磨吐块是一条新途径。

The high silicon and low iron difficult-to-grind ore from the mills is dense,which is used as auxiliary material in the industrial test of smelting ferromanganese-silicon.Good results are achieved such as producing smoothly,reducing the amount of high price ferromanganese in raw materials and lowering production cost.A new way is found out to reduce the cost of ferromanganese-silicon with the utilization of difficult-to-grind ore from the mills.
