Head Toryanik T.I., Registration Date 26-10-2006 Organization Ukrainian State Researsh Institute for Carbochemistry popup.description2 The determination was done for composition and quality of the delivered concentrates. Using the values of classification parameters the coal grades were specified for the raw base of the plant. Certain coal grades were recommended to consider as law-sulphur heterogeneous law-caking components of a blend. Their share part in the blend for coking should be 15-20 % by mass depending on the level of caking ability. Investigations of the industrial and experimental blends are carried out for improving coke quality.. A grade estimation express- method was developed as per the index of optical density of extract from coal with dimethylsulphoxyde. The developed measurement method for extract optical density was recommended both for entrance control of the delivered concentrates and for operative control of blend composition and quality at charging a coal tower, as well as for coke quality stabilization.
