摘要:

中国已将炼焦煤资源中的肥煤(含气肥煤)、焦煤(含1/3焦煤)、瘦煤规定为“特殊和稀缺煤”。通过研究低质“特殊和稀缺煤”之间的配伍性,合理搭配该类煤,在优质“特殊和稀缺煤”焦煤、肥煤配入比例降至3%,无高变质程度炼焦煤的情况下,制备出高强度冶金焦。

Abstract:

China has classified fat coal (including gas-fat coal),primary coking coal (including 1/3 coking coal) and lean coal as “special and scarce coal”.The compatibility of different kinds of low-quality “special and scarce coal” is studied.By blending with appropriate amount of these coals,i.e.under the condition of the proportion of high-quality “special and scarce” coking coal and fat coal reduced down to 3%,and no coking coal with high metamorphic degree,high strength metallurgical coke can be produced.
