FIELD: production of metallurgical coke.
SUBSTANCE: used as baking additive is ground sapromyxite coal of Barsass deposit of Kuznetsk coal field; first content of ash and pyrites sulfur is decreased to 9.5-10%; then, sapromyxite coal is subjected to ultra-fine grinding to size of particles of 5-50 mcm followed by mixing with fat coal, gas-fat coal, slightly baking coal and lean-baking coal at addition of coals of power-generating ranks.
EFFECT: reduced specific content of coals of more valuable ranks; enhanced strength of metallurgical coke; low cost of process; reduced specific consumption of coke in melting of cast iron; enhanced efficiency of blast-furnace process.
