VORTEX INHIBITOR WITH SACRIFICIAL ROD

摘要

An improved vortex inhibitor (22) for separating slag from molten metal duri ng the discharge of molten metal through a nozzle (14) includes a uniform castable refractory body (24) with a generally tapering shape, a hollow chamber (30) within the body and an elongated sacrificial member (32). The hollow chamber receives the sacrificial member or a mount for the sacrificia l member. The refractory body (24) and the sacrificial member (32) 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 hollow chamber (30) can fill with molten metal to form a core tha t aids in orienting the body in a narrow end downward position. The sacrificia l member align the with the area in which the vortex forms and minimizes interference with the flow through the discharge nozzle (14). The body (24) preferably includes swirl obstructing surfaces.
