UP-DRAWING CONTINUOUS CASTING METHOD

摘要

An up-drawing continuous casting method according to one aspect of the invention is an up-drawing continuous casting method for forming a bent shape in a cast casting by forming the casting in a first direction and then changing an up-drawing direction to a second direction and forming the casting in the second direction. This up-drawing continuous casting method includes drawing up the molten metal in the first direction; and changing the up-drawing direction to a third direction in which an angle between the third direction and the first direction is greater than an angle between the second direction and the first direction, from after a portion that will have the bent shape passes through the molten metal passage portion until the portion that will have the bent shape reaches a solidification interface, and then drawing up the molten metal.

1. An up-drawing continuous casting method for forming a bent shape in a cast casting by forming the casting in a first direction and then changing an up-drawing direction to a second direction and forming the casting in the second direction, the casting being formed by drawing up molten metal held in a holding furnace from a molten metal surface of the molten metal, passing the molten metal through a molten metal passage portion of a shape determining member that determines a sectional shape of the casting, and solidifying the molten metal, the up-drawing continuous casting method comprising:
drawing up the molten metal in the first direction; and changing the up-drawing direction to a third direction in which an angle between the third direction and the first direction is greater than an angle between the second direction and the first direction, from after a portion that will have the bent shape passes through the molten metal passage portion until the portion that will have the bent shape reaches a solidification interface, and then drawing up the molten metal.
