摘要使用低品位铬铁精矿（或粉矿）是提高不锈钢产品市场竞争力的有效措施，对精粉进行预先造块是提高熔炉冶炼效率、降低焦比不可缺少的步骤。回顾了中南大学使用低品位南非铬铁精矿制备高品质炉料用于高炉冶炼不锈钢母液工艺的相关研究及经验。前期扩大试验表明，任意铬铁精矿比例条件下均可制备出高强度氧化球团（＞2 500 N/个）和烧结矿。高压辊磨预处理是强化铬铁精矿造块的关键技术。为获得满足高炉冶炼要求的炉料冶金性能，南非铬铁精矿的使用比例应低于60%。球团烧结技术是对细粒铬铁精矿造块有效且较经济的技术手段，所得含铬烧结矿用于高炉冶炼不锈钢母液工艺是可行的。

Abstract：The utilization of low grade chromite concentrates or fines is an effective way to improve the competiveness of stainless steel products in the market.Preliminary agglomeration of these concentrates or fines is an essential step to improve the reduction efficiency and reduce the coke ratio of the smelting process. Earlier researches and experiences of Central South University in producing high quality feedstocks from low grade chromite concentrates for alternative production of stainless steel master alloys in blast furnaces were summarized. Pilot-scale tests showed that both high strength oxidized pellets （over 2 500 N/pellet） and sinters could be manufactured from any proportion of chromite concentrate. High pressure grinding rollers （HPGR） pretreatment is a key technique to strengthen the agglomeration of chromite concent rates. To achieve a desirable metallurgical performance of agglomerates in blast furnaces， the proportion of chromite concentrate should be less than 60%. Pellet-sintering technique is an effective and economic method for the agglomeration offine chromite concentrates. It is feasible to use the chromium-bearing sinter as the charging material for stainless steel master alloys production in blast furnaces.
