本文以法国某钢铁公司400m~3高炉使用100%加蓬锰矿冶炼锰铁、富锰渣和1985年上海铁合金厂21m~3高炉冶炼双种产品的实践,结合我矿锰铁高炉生产时锰回收率低、水渣无销路,严重影响生产正常进行的现状,试图寻找一条既摆脱困境,又提高经济效益的途径。为此,利用我矿70—100m~3富锰渣(或锰铁)高炉试产双种产品,摸索冶炼规律,以达目的。
In this paper, a French iron and steel company 400m ~ 3 blast furnace using 100% Gabon Manganese ore smelting ferromanganese, manganese slag and 1985 Shanghai Iron Alloy Plant 21m ~ 3 blast furnace smelting two products, combined with the production of manganese ore blast furnace manganese recovery Low, no sales of water slag, seriously affecting the normal production of the status quo, trying to find a way out of predicament, but also improve economic efficiency. To this end, the use of mine 70-100m ~ 3 manganese-rich slag (or ferromanganese) blast furnace trial production of dual products, explore the law of smelting, in order to achieve the goal.
