INSTALLATION FOR DIRECT MELTING Russian patent published in 2011 - IPC C21B11/00 C21B13/00 

FIELD: metallurgy.

SUBSTANCE: installation consists of stationary tank for direct melting with liquid bath, of unit for supply of solid substances containing multitude of tuyeres for introduction of solid substances, of unit supplying oxygen containing gas with multitude of tuyeres for gas injection and of gas supplying main passing around total periphery of tank and positioned at distance from this tank, of spent gas withdrawal unit, of metal pouring unit and of unit for discharge of slag. The installation also consists of multitude of access zones for a bridge crane. These zones are arranged further from centre of the tank relative to the gas supply main to facilitate removal of tuyeres for introduction of solid particles from orifices in a side wall of the tank for direct melting and facilitate arrangement of replaceable tuyeres in these orifices. The installation also consists of multitude of access zones for a bridge crane. These zones are arranged closer to centre of the tank relative to the gas supply main to facilitate removal of tuyeres for gas injection from orifices in a side wall of the tank and facilitate arrangement of replaceable tuyeres in these orifices.

EFFECT: production of over 1 million ton of melted iron per year by Hismelt process.

35 cl, 14 dwg
