INSTALLATION FOR REDUCTION SMELTING AND OPERATING METHOD OF REDUCTION SMELTING Russian patent published in 2016 - IPC C21B11/00 F27B1/16 

FIELD: technological processes.

SUBSTANCE: invention relates to method and apparatus for reducing melting. Plant includes loading device for solid carbon carriers and iron containing charge components, melting gasification area, which comprises stationary layer formed by solid carbon carriers and iron containing components of charge, lower section to receive liquid cast iron or, respectively, steel semi-finished product, and liquid slag, tap hole for discharge of liquid slag and liquid cast iron, oxygen blowing Tuyere for oxygen supply. At that, Tuyere are arranged in at least two spaced apart, in particular in vertical direction, and located parallel to each other Tuyere caissons zones, and distributed along horizontal plane around the perimeter of installation for reduction smelting, and in different zones of Tuyere caissons are shifted relative to each other. Vertical distance between Tuyere belts, in particular, vertical distance between tuyeres outlets, is less than or equal to horizontal distance between oxygen blowing tuyeres.

EFFECT: invention provides reliable operation of the plant, higher efficiency.
