神华煤的基本特征及配入炼焦对焦炭热性质的影响

低变质程度的神华煤就其本身性质而言不能用于炼焦生产,但是为了扩大其应用范围,同时缓解中国炼焦煤资源紧缺的现状,有必要进一步探讨神华煤的焦化特性。笔者较系统研究了神华煤的基本特征、煤岩特征及不同比例配入炼焦时对焦炭热性质和光学显微组织的影响。 Shenhua coal that is a kind of low rank coal is a sort of non-coking coal. Due to enlarge the applied area of Shenhua coal and be short of coking coal,Shenhua is put to use in the process of coal blending produce. In the coal blending test,the different proportion of Shenhua coal must be affect the coking property of coke strength(CRI、CSR)and the optical microstructure of coke
