Abstract

339,802. pneulec, Ltd., and Parry, H. J. Dec. 20, 1929. Crucible furnaces; discharging. - A vertical groove g is formed in the furnace lining to allowa crucible e with a side tapping spout h to be lowered into position. The spout rests on a ferrule m inserted in a bell mouth j fitted in the furnace wall and having an extreme lip f. The spout is formed with a shouldered inner end n, and is cast into the crucible. The discharge of molten metal is controlled by a tapered plug, and a cold air pipe v is directed into the mouth to freeze the metal around the plug. Heating gases may be deflected over the metal in the crucible by a lip r.
