摘　　要：通过自主开发并引进了山西地区和蒙古地区新煤种,并利用SXLLSJM、SXJM及HDSJM,部分替代ZYDM和LLGHM等供应紧张煤种,增加4个新煤种,扩大了捣固炼焦用煤范围,缓减用煤紧张趋势,同时优化现有捣固炼焦配煤结构,改善了焦炭质量,焦炭灰分降低,焦炭热强度提高,为包钢高炉稳定顺行提供了强有力的燃料支撑。Four new types of coal are increased through developing independently and introducing the new types of coal in Shanxi and Inner Mongolia as well as utilizing the SXLLSJM、SXJM and HDSJM,part of which is instead of such types of coal with tension supply as ZYDM and LLGHM.As a result,the scope of coal used for rammed-coal coking is expanded,tension trend of using coal is relieved,the existing coal blending structure of rammed-coal coking is optimized and coke quality is improved.The ash content of coke is reduced and the hot strength of coke is increased,which provide the strong fuel support for the stable and trouble-free operation of blast furnaces of Baotou Steel.
