目前冶炼錳铁的高爐,大多存在着生产率不高、錳回收率低等缺点。为此着重提出以下几个问题供大家参考。一、加强原料管理和冶炼普通生鉄的高爐一样,錳铁高爐技术经济指标的好坏,与原料質量的关系极为密切。对錳矿石的要求是:含Mn高且均匀、SiO_2及其他杂質的含量要小、Mn/Fe比值要高、粒度整齐。現在某些高爐由于使用的錳矿石質量不好,給高爐操作带来一定困难。
At present, blast furnaces that ferromanganese and iron are mostly shortcomings of low productivity and low recovery rate of manganese. To this end, we put forward the following questions for your reference. First, to strengthen the management of raw materials and smelting ordinary raw blast furnace, ferromanganese blast furnace technical and economic indicators of good or bad, and the quality of raw materials is very closely related. Manganese ore requirements are: high and uniform Mn, the content of SiO2 and other impurities should be small, Mn / Fe ratio is high, granularity neat. Now some of the blast furnace due to the poor quality of the use of manganese ore, blast furnace operation to bring some difficulties.
