Title:
COOLING METHOD FOR MOLD AND CASTING DEVICE
Document Type and Number:
Japanese Patent JP3299506
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve the life of a mold for a large ingot by swinging a jet gas from a plurality of jet nozzles arranged in a casting chamber or a casting pit on an outer periphery of the mold, and reducing the time when an inner face of the mold is held at more than a given temperature.
SOLUTION: For example, a mold 1 is installed on a stand board 4 in a vacuum chamber 6 arranged in a pit, and a feeder frame 3 is disposed thereon for carrying out vacuum casting. Eight gas jet nozzles 5 are arranged inside the vacuum chamber 6 at equal intervals in a manner to surround the mold 1, and gas jet nozzle groups 5a, 5b, 5c are arranged in three lines in a height direction. The jet direction of the gas jet nozzle groups is 45° towards a center portion of the vacuum chamber 6 to the tangent of the inner perimeter of the vacuum chamber 6. The jet gases from the gas jet nozzle groups are swung in the same direction between the inner face of the casting chamber and the outer peripheral part of the mold after casting, so as to reduce the time when the mold inner face is held above 650°C.
