The invention relates to ferrous metallurgy, in particular to the blast-furnace production, and can be used for operation with a gas flow circumferentially to the blast-furnace mouth, equipped with non conical charging device and equipped with a measuring equipment facilities of distance to the surface of stockline. A difference in descent speeds of charge materials and/or the distortion of stockline profile circumferentially to the furnace is compensated by the change of time for unloading of portion on a value, which provides passing by the distributor of sector, in which necessary compensation is single-order greater or less. The technical result is increasing operationability of control, optimization of the modes of charging and decrease of coke expense for cast-iron smelting. |
