Abstract

This invention relates to a casting machine furnace apparatus including a casting machine furnace, a supply furnace in fluid communication with the machine furnace and operative to supply a molten metal to the machine furnace, and a stopper module device disposed in a fluid path between the casting machine furnace and the supply furnace. The stopper module device includes a block housing and a stopper assembly. The block housing includes an inlet opening and an outlet opening, and is disposed in the fluid path. The stopper assembly is supported for movement relative to the inlet opening of the block housing between a working position, wherein the molten metal flows from the supply furnace to the casting machine furnace, and a non-working position, wherein the flow of molten metal is prevented.
