Title: Method for manufacturing ingots of high-melting ferroalloys and metal alloys with good forming properties

Abstract: Ingots of high-melting ferroalloys and metal alloys with good forming properties are obtained by melting a consumable electrode in a slag bath in an ingot mold while cooling the ingot mold and providing a high pressure gas inert to the slag above the slag bath. The apparatus is a trisectional pressure chamber including an ingot mold which may be surrounded by a pressure container, a bell-type distributing device surrounding and extending above the mold, a cap for the distributing device through which a guide rod for a consumable electrode is introduced into the mold and a gland mounted in the cap for sealing the pressure chamber.
