REVERBERATORY FURNACE FOR METAL REMELTING Russian patent published in 2009 - IPC F27B3/00 C22B7/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to reverberatory furnace for remelting of aluminium breakage. Furnace contains case, formed by side, front and back end walls, limited by bottom and walls accumulative bath, crown, two discharge tap holes, flue duct and fabricated frame, on which everything is located. Furnace can operate on natural and artificial draw with gas purification system, that makes breakage remelting process as environmentally friendly. In furnace it is external heat insulation of walls consisting of 3 layers of heat-insulating materials: chamotte granulated material, fireproof cotton, double layer of asbestos cardboard. Inclined platform, accumulative bath are bricked of baked in the hearth blocks "ШСУ" 33-1, laid for three layers of asbestos cardboard, and wadding made of dry high-silica sand, that provides heat keeping in furnace bath, interrupting its offtake to binding. In furnace it is installed special quick-detachable tapping brick in metal casing, which can be easily changed for the new one in case of its wear without disassembly of butt and two side walls.

EFFECT: design simplification and reduction of heat losses.
