A METHOD FOR A BLAST-FURNACE CHARGING

Method for a blast-furnace charging consists in common charging of coke nut, 8 - 40 mm in size, in amount up to 25 % of total mass of coke in the layer, and of the furnace charge ore component, in a separate skip, at each charging or in one-ten events of charging. The coke nut loading is performed t...

Zusammenfassung:	Method for a blast-furnace charging consists in common charging of coke nut, 8 - 40 mm in size, in amount up to 25 % of total mass of coke in the layer, and of the furnace charge ore component, in a separate skip, at each charging or in one-ten events of charging. The coke nut loading is performed to the ore component of the charge, having the minimal reducing power among all the ore components, with separating that ore component to two parts, 30 -70 % of the total mass, and with initial placing coke nut between those, at that the total mass of the ore component is to be not less than 4.0 times larger than the mass of the coke nut.
