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

FIELD: metallurgy.

SUBSTANCE: furnace contains body, formed by side, front and back end walls, limited by bottom and walls accumulative bath, crown, exhaust notch, flue duct and fabricated frame, at which everything is located. In furnace it is external walls heat-insulation, consisting of three layers of heat insulators: chamotte granulated material, fireproof cotton, double layer of asbestos cardboard. Inclined platform, accumulative bath are lined from car-top blocks "МКРС-50", lined in three layers of asbestos cardboard and tamping made of dry high-silica sand, that provides to keep heat in furnace bath, interrupting its withdrawal to the binding. Furnace binding is poured by concrete with additions of chamotte granulated material, and in top part of which are lined in two layers lightweight chamotte bricks, reducing thermolysis from bath through binding. Crown over the inclined platform and furnace bath allows heat insulating coating material in two layers and two layers of fireproof mats, which additionally reduce heat losses from melting area of furnace. In furnace there are installed seven injection burners of type "БИТ" for implementation of melting forced operation.

EFFECT: design simplification and heat losses reduction.
