METHOD OF PRODUCING AND SMELTING HOT METAL OR LIQUID INITIAL PRODUCTS IN MELTING GAS GENERATOR Russian patent published in 2013 - IPC C21B11/00 C21B13/00 F27D3/16 

FIELD: metallurgy.

SUBSTANCE: iron oxides or pre-oxidised iron and carbon-bearing material are fed with carbon-bearing material gasification by introduced oxygen-bearing gas. The latter is forced by, at least, one oxygen tuyere and fed by, at least, two gas flows into steady-state bed of melting or carbon gas generator. Note here that oxygen tuyere has, at least, one oxygen feed channel and, at least, two oxygen flow discharge channels with outlets. Note here that every oxygen flow discharge channel communicates with one oxygen feed channel while central axes of oxygen flow discharge channel outlets form the angle of 5°-15° between them.

EFFECT: sufficient feed of oxygen without loss in steel case strength and with ruled out decrease in fluidisation of steady-state bed.
