近年来,包钢在烧结料中配加一定量的含镁熔剂,使烧结矿MgO含量维持在2.5～3.0％,显著地改善了烧结矿的冶金性能。高炉使用65～70％高MgO烧结矿,不仅使炉渣成份趋向合理,提高了热稳定性,而且高炉冶炼也取得了防瘤、顺行、高产、优质和低耗的重大进步。因而,MgO已成为烧结矿配料中不可缺少的添加剂。但是,对于MgO在烧结矿中所起的作用过去研究得还不够;对高炉冶炼使用MgO烧结矿的作用至今认识也不尽相同;有的人还主张降低包钢烧结矿MgO含量。本文试图通过国内外关于MgO烧结矿的研究和发展情况并结合
In recent years, Baotou Steel in the sintering material with a certain amount of magnesium flux, the sintered ore MgO content was maintained at 2.5 to 3.0%, significantly improving the metallurgical properties of sinter. The use of 65-70% high MgO sinter for the blast furnace not only makes the slag composition more reasonable, but also improves the thermal stability. In addition, blast furnace smelting has also made significant progress in anti-tumor, on-going, high yield, high quality and low consumption. Thus, MgO has become an indispensable additive in sinter formulations. However, the role played by MgO in sinter has not been studied sufficiently in the past. The role of MgO sinter in blast furnace smelting has not been fully understood until now. Some people also advocate the reduction of MgO content in sinter ore. This article attempts to pass the domestic and foreign research on MgO sinter and development and combination
