Title:
CONTINUOUS MELT SUPPLY SYSTEM FOR METAL CASTING
Document Type and Number:
WIPO Patent Application WO/2011/117931
Kind Code:
A1
Abstract:
The disclosed continuous melt supply system for metal casting is formed from a holding furnace (2) and a melting furnace (1) for tilting the furnace body and discharging molten metal, and is provided with a casting trough (4) and a melt moving trough (3) for discharging melt (M) at melt discharge openings in the holding furnace (2) and the melting furnace (1). The holding furnace (2) is lifted, and a steady flow amount of melt (M) is supplied to a casting machine casting trough (5) via the casting trough (4). After the lifting of the holding furnace (2), said lifting is stopped and the holding furnace is lowered whilst continuing the discharge of melt. The melting furnace (1) is lifted, and a steady flow amount is melt-moved to the holding furnace (2) which is being lowered, via the melt moving trough (3). As the holding furnace (2) is being lowered said furnace receives melt from the melting furnace (1), and simultaneously discharges a constant flow amount of melt. After the lowering of the holding furnace (2), said lowering is stopped and the holding furnace is lifted whilst continuing to discharge melt. This operation is repeated until casting is completed.
