HOLDING FURNACE FOR VERTICAL SEMI-CONTINUOUS CASTING

摘要

A holding furnace for vertical semi-continuous casting that can improve quality of copper alloy by supplying the molten metal in an inert gas atmosphere such that molten metal supplied from the holding furnace to molds through a tundish is not exposed to the air and automatically checking and controlling an amount of the molten metal supplied to the molds through the tundish is provided. A holding furnace for vertical semi-continuous casting comprises: a crucible(110) into which molten metal supplied from a melting furnace is supplied so that the molten metal is stored in the crucible; a tundish(120) for receiving molten metal from the crucible and distributing the molten metal into respective molds(M); a thermal insulating member(130) for covering the crucible and the tundish such that an empty space(S) is formed between the crucible and the tundish; a resistance heating type heater(140) installed in the space formed by the thermal insulating member to generate heat using electricity applied to the resistance heating type heater; a gas supply part(150) for injecting an inert or reductive gas into the space formed by the thermal insulating member; a first molten metal supply part(160) connected from the crucible to the tundish and operated by a first sensing part for sensing a molten metal amount of the tundish to maintain the molten metal amount of the tundish in a predetermined range; and a second molten metal supply part which is installed on a lower end of the tundish to open or close injection holes(121) for injecting molten metal into the molds and is operated by a second sensing part for sensing a molten metal amount of the molds.
