SEMICONTINUOUS CASTING METHOD OF METAL |
摘要 |
PURPOSE:To prevent the generation of bumping, by injecting a gas to the bottom part of a cast ingot from a through-hole which opens in the top surface in the central part of a freely vertically movable receiving base for supplying molten metal from a water cooled casting mold opened at the top and the bottom and penetrates to the lower part or side surface of the receiving base and casting said ingot. CONSTITUTION:A receiving base 1 is inserted into a casting mold 5 and the molten metal 7 in a well 4 for molten metal is supplied 4' continuously into the mold 5. A cast ingot 8 is drawn out downward while the base 1 is moved downward and cooling water 6 is applied on the ingot 8. The casting is completed while the cooling water entering the clearance 9 between the ingot 8 and the base 1 is blown away forcibly to the outside by the gas injected through a piping 3 and the through-hole 2 of the base 1 in the stage when the bottom part of the ingot 8 solidifies to have strength. The generation of bumping is thus prevented thoroughly. The opening position of the hole 2 on the surface of the receiving base is preferably within 1/2 of the width and thickness from the center of the base 1. |
