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. In furnace it is external walls heat insulation, consisting of four layers of heat insulators: chamotte granulated material, fireproof cotton, triple layer of asbestos cardboard, asbestine granulated material. Inclined platform, accumulative bath are bricked of baked in the hearth blocks "МКРС-50", 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. Furnace binding inside is lined by moler brick, reducing heat loss from bath through the binding. Crown over inclined platform and furnace bath allows heat insulating patching material in two layers, consisting two layers of fireproof mats, layer of moler brick, which additionally reduce heat losses from the melting space of furnace. In furnace there are installed six injection burners of type "БИТ" 2-6 for introduction of forced melting operation. Furnace allows two tap holes, implemented in quick-change tapping bricks in metallic binding, that provides implementation of its change without furnace stopping for repair and excluding destruction of crown and walls. It is provided design simplification and reduction of heat losses.

EFFECT: design simplification and reduction of heat losses.
