METAL-CASTING METHOD AND APPARATUS, CASTING SYSTEM AND CAST-FORGING SYSTEM

摘要

An automatic continuous casting system for producing a cast body, comprising: a casting apparatus that makes use of unidirectional solidification of molten metal and includes a molten metal reservoir (4) and a mold (5), in which molten metal in a molten metal source (2) is supplied through transfer means (3) to the molten reservoir, and the molten metal (45) supplied into the molten metal reservoir is suplied through an opening/closing plug (43) into the mold; target weight calculation/storing means (8) for calculating, on the basis of compositional proportions of metal elements contained in the molten metal (45), a specific gravity of an alloy obtained through solidification of the molten metal, calculating a target weight of a cast body on the basis of the specific gravity of the alloy and a capacity of the mold, and memorizing and storing the target weight; and first molten metal supply amount regulation means (9) for regulating an amount of the molten metal supplied from the molten metal reservoir into the mold by obtaining a measurement weight of the cast body and comparing a measurement weight of the cast body and comparing the measurement weight with the target weight.
