FIELD: metallurgy.
SUBSTANCE: invention relates to receiving of coal briquette, used during the receiving of liquid cast iron in facility for melting-gasification. For receiving of coal briquettes with usage of coal with wide particles distribution by dimensions implemented initial classification of the first group of coal by particles sizes for receiving of fine coal. Fine coal is mixed to the second group of the coil with the mean reflection coefficient (Rm) 0.8 or higher. Coal mixture including fine coal from the first group of coal and the second group of coal are dried and implemented secondary classification of this coal mixture by particles size with receiving of sizes of coal grains equal or less than established dimension for charging in facility of melting-gasification. To the coal mixture with grain size equal or less than established size for charging into facility of melting-gasification it is added curing agent and molasses binder, there are mixed and manufactured coal briquettes by means of moulding of this coal mixture.
EFFECT: development of effective method of receiving of coal briquettes, used during the receiving of liquid cast iron in facility for melting-gasification.
