Document Type and Number:
Japanese Patent JP2000501653
Kind Code:
A
Abstract:
An apparatus (10) for casting metal ingots comprises a series of ingot moulds (12) mounted along an endless conveyor (11) which is arranged to be driven around spaced-apart rotatable members (15) and (17). A molten metal supplying device (20) has a discharge member for supplying molten metal to empty moulds (12) moving along an upper run (14) of the conveyor (11) from a supply end (16) to a discharge end (18) of the upper run (14) of the conveyor (11). A casting hood (13) overlies at least a portion of the moulds (12) on the upper run (14) of the conveyor (11). Adjacent moulds (12) of the portion of moulds are closely contiguous during passage beneath the casting hood (13) whereby passage of protective gas between said adjacent moulds is minimized. The casting hood (13) and the portion of moulds (120) form a substantially gas-tight enclosure above the portion of moulds (12) into which gas can be introduced. The enclosure houses the discharge member of the molten metal supplying device (20).
