FURNACE FOR PROCESSING OXIDIZED ORE MATERIALS CONTAINING NICKEL, COBALT, IRON Russian patent published in 2008 - IPC F27B17/00 

FIELD: metallurgy, namely aggregates for continuous melting of oxidized nickel-containing raw materials.

SUBSTANCE: furnace includes caisson shaft divided by means of vertical cross partition by melting and reducing chambers provided with tuyeres; united stepped along chambers hearth; siphon with over-flow duct and with openings for discharging slag and metal-containing melt. Vertical cross partition dividing chambers is mounted fluid-tightly in hearth of melting chamber and it has height equal to 35 - 55 diameters of tuyeres of melting chamber over plane of their arranging. Hearth of reducing chamber is inclined by angle 25 - 60° to horizon from vertical cross partition towards over-flow duct.

EFFECT: possibility for providing continuous stable processing of oxidized ore materials, improved efficiency of furnace, extraction of non-ferrous metals to metal-containing melt, lowered consumption of fuel, reducing agent, sulfidizing agent, decreased expenses for melting.
