Title:
犠牲ロッドを備えた渦抑制装置
Document Type and Number:
Japanese Patent JP4318919
Kind Code:
B2
Abstract:
An improved vortex inhibitor for separating slag from molten metal during the discharge of molten metal through a nozzle includes a uniform castable refractory body with a generally tapering shape, a shaft within the body and an elongated sacrificial member. The shaft receives the sacrificial member or a coupling for the sacrificial member. The refractory body and the sacrificial member combination in molten metal has a specific gravity less than the specific gravity of molten metal and is positioned narrow end downward when supported in molten metal. The sacrificial member aligns the vortex inhibitor with the area in which the vortex forms and minimizes interference with the flow through the discharge nozzle.
