PROCESSING METHOD OF METALLURGICAL RAW MATERIALS AND DEVICE FOR SUCH METHOD IMPLEMENTATION Russian patent published in 2017 - IPC C22B7/00 C21B11/00 C22B5/12 

FIELD: metallurgy.

SUBSTANCE: method involves the preparation of the initial molten slag bath by filling a mobile capacity with slag, discharged from various metallurgical units. Then the supply to the molten stock is performed, consisting of the feedstock, solid carbonaceous material and fluxes, and the melt blowing by air and heating gas. The device consists of a container with the melt, immersion chamber without bottom, connected with a suction device and the movement mechanism. The chamber dome has the integrated multichannel vertical double-level tyere-burner, the stock is supplied along its central channel, injected by the air, and along the periphery ones - the air and heating gas, directly just below the level of the initial bath of molten slag.

EFFECT: efficiency increase of the reduction smelting in the liquid slag bath, while reducing the number of used units, reduction of capital and energy costs, improved environmental performance.
