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 regular pyramidal shape. The tapered body includes swirl obstructing surfaces extending along its length and is geometrically proportioned so that the center of gravity is closer to the apex than the center of buoyancy of the body. Preferably, the outermost parts of the base intersect a circle whose diameter is larger than the diameter of the nozzle opening and defining a base length dimensionally fixed with respect to the base length within a predetermined range. Preferably, the longitudinal height is in the range of 0.5 to 1.0 times the diameter of the circumscribed circle. A modified, spherically configured body which can be rolled into position also is geometrically proportioned to keep the center of gravity spaced from the center of buoyancy and closer toward the apex of the modified shape.
