摘要
本文主要探讨采用《煤样的制备方法》GB 474-2008进行煤样的制备,但因对该标准的理解和关注焦点不同而制备的煤样,导致烟煤黏结指数存在较大的差异性。本文阐述了炼焦煤进供双方黏结指数的差异主要来源于炼焦煤黏结指数煤样制备环节。
The dissertation mainly investigates the preparation of coal sample according to coal sample preparing method in GB 474-2008, however, it is the different understandings of this standard and the diverse focuses of attention that causes a bigger difference of caking index of bituminous coal. With regard to the difference of caking index between the supplier and distributor of coking coal, the article expounds on the reason, which roots in the preparation steps of coal sample.
