FIELD: chemistry; metallurgy.
SUBSTANCE: pulverised coal fuel for blast-furnaces contains finely ground gas-coal, to whose content is additionally added finely crushed coke breeze, obtained from heat treated inert carriers of gaseous low-sulphur coal. Heat treatment of inert carriers in carried out at temperatures 150-250°C.
EFFECT: intensification of combustion of pulverised coal fuel in the tuyere region, increase in the percentage of substitution of coke with pulverised coal fuel, increase in the production of a blast-furnace and tuyere-zone temperature, decrease in the cost of iron manufacture in blast-furnaces.
