Title: Method for pouring molten metal in vertical casting machine
Inventor: NISHIURA TAKESHI
IPC: B22D18/02
Filed: 1993-03-23
Abstract: PURPOSE:To reduce the fall of molten metal, to restrain the spattering of the molten metal and to avoid the effect to the casting quality causes by the spattering by pouring the molten steel in the condition of inserting of inserting a bottom-pouring type ladle into at least the inner part of an upper die from a pouring hole. CONSTITUTION:The ladle 31 containing the molten metal M beforehand is entered from the pouring hole 37 and slowly descended through a runner part 38 and a product part space R, and at the time of inserting the lower end of this ladle 31 into a pressurizing sleeve 25, this ladle is stopped. Then in the still state of the ladle 31, a stopper 35 is pulled up to open a pouring hole 33 and the molten metal M is poured into an upper space R of a pressurize-plunger 12. At this time, initially, the molten metal is slowly poured without fully opening the pouring hole 33 at once, and after storing the molten metal M to some extend, by fully opening the pouring hole 33, the spattering of the molten metal M is restrained. Further, even if the spattering of the molten metal M is generated, as the fall from the ladle 31 to the pressurizing sleeve 25 is short, the spattering of the molten metal M does not reach the product part space R and the pouring hole 37.
