Casting, vertical casting method and vertical casting apparatus
A molten steel of a special steel or the like including a high-alloy steel is poured in a mold whose bottom portion is closed with a dummy head of a lift table. As the lift table is vertically moved down at a given casting speed, a casting whose lower end is supported by the dummy head is continuously pulled out from the bottom portion of the mold. As a pair of movable molds that constitute the mold are relatively moved away from each other in synchronism with the downward movement of the lift table, both widthwise side surfaces of the casting are provided with required tapering.
