Title:
METHOD AND SYSTEM FOR FILLING MOLTEN METAL IN CENTRIFUGAL CASTING EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2005/002758
Kind Code:
A1
Abstract:
A method and a system for filling molten metal in centrifugal casting equipment, the equipment comprising a device (11) using a large capacity molten metal ladle (14) capable of casting a plurality of cast tubes and allowing the ladle to be rapidly replaced when an operation is moved from a previous casting operation to a next casting operation and a means for accurately controlling the position and speed of the molten metal falling from the molten metal ladle (14) onto a chute (25), wherein the fallen position of the molten metal is controlled in consideration of the displacement of the fixed point of a tap hole (24) following the inclination of the ladle, a molten metal filling rate is controlled based on the molten metal surface area in the ladle and, when at least first cast tube is cast, the molten metal filling ladle (14) is tilted to an angle provided immediately before the start of filling of the molten metal, and remaining molten metal and residue are discharged to a residual molten metal pot by laterally moving and inversing the molten metal filling ladle (14).
