ABSTRACT:
An anti-slag, anti-vortex tundish measurement apparatus for use in tundishes or other molten metal receptacles provides a measurement of the depth of the molten metal layer above the bottom of such receptacles. The apparatus includes a body mounted on a first end of an elongated rod. The body and the rod are formed of a suitable material and have a predetermined size such that the specific gravity of the body and the rod is less than the specific gravity of the molten metal in the receptacle; but greater than the specific gravity of the slag layer covering the top of the molten metal layer such that the body is buoyantly supported at the interface between the slag layer and the molten metal layer. Measurement indicia in the form of incrementally spaced, scale gradations is formed on the second end of the rod, which end extends externally from the interior of the molten metal receptacle. A cover mounted on the molten metal receptacle slidably receives the second end of the rod therethrough such that the measurement indicia on the rod is disposed externally from the molten metal receptacle.
