VESSEL, MOLTEN METAL SUPPLYING METHOD AND MOLTEN METAL SUPPLYING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a vessel in which it is unnecessary to perform an exchange of a part such as a stoke. SOLUTION: This vessel is provided with a closed vessel body 50 which can store molten metal such as molten aluminum alloy, a flowing passage 57 for molten metal which extends toward the upper part 57b at the outer periphery of the vessel body 50 through an opening hole part 57a arranged in a position near the bottom part 50a of this vessel body 50 at the inner periphery of the vessel body 50, and means 101, 313 for adjusting pressure in the vessel body. Then, the effective inner diameter of piping for making flow of the molten metal is characteristically larger than about 50 mm and smaller than about 100 mm.
