MELTING FURNACE Russian patent published in 2010 - IPC F27B3/24 F27D1/12 F27D9/00 

FIELD: metallurgy.

SUBSTANCE: melting furnace consists of case with sole, upper side part and lining, of jacket, of sole part cooling system and of furnace upper part cooling system. The furnace upper part cooling system is made as circular-form pipe positioned at an upper edge of the jacket around its external surface. Branches for drain of fluid, directed onto surface of the jacket between vertical ribs of the upper part of the jacket, are uniformly distributed on the pipe. The upper part of the jacket is separated from the jacket of the sole part with a ledge of box shape connected with pipes for fluid drain. The cooling system of the sole part is made as a funnel-like reservoir enveloping the bottom and a lower part of the side wall of the sole with a gap and connected with installation for supply of gaseous medium. The circular-shape pipe of the furnace upper part cooling system is joined to a fluid cooling station.

EFFECT: raised reliability of furnace due to its upper part external cooling and due to free flow of cooling medium along walls of sole part.
