DEVICE FOR METAL MELTING WITH ELECTRON BUNCH AND PROCEDURE IMPLEMENTING THIS DEVICE FOR FABRICATION OF INGOT OUT OF METAL WITH HIGH TEMPERATURE OF MELTING Russian patent published in 2010 - IPC C22B9/22 F27D1/00 

FIELD: metallurgy.

SUBSTANCE: furnace consists of mechanism for raw material supply, of melting device connected to mechanism of supply and limited with wall and furnace roof and containing at least sole, of water-cooled crystalliser, of electron gun and of device for fume extraction coupled with melting device. On at least one element out of a row including the wall and the roof the furnace has lining out of titanium or stainless steel, and additionally there is multitude of laminar elements made out of titanium or stainless steel arranged on the roof. According to another version on internal surface of the furnace there is installed removable lining consisting of roof lining made out of metal, side wall lining and bottom lining made out of metal or resin. Each kind of lining can be removed from the furnace separately.

EFFECT: invention prevents intrusion of new contaminants into ingot and reduces probability of penetration of once evaporated impurities from bath of melt metal onto sole or into crystalliser; also invention raises operating factor of furnace.
