ABSTRACT:
A sampling cavity for sampling molten metals includes a cavity body for receiving a measured sample of a molten metal, and, an insert containing a material for promoting carbide formation in the molten metal as it cools, the insert being in the form of an enclosed capsule formed of thin polymeric walls containing the material in finely divided solid form. The insert may be adhered within a fill inlet passage or attached at the bottom of a cup sampler having an open top either by being adhered directly to the cavity surface or by being supported in a supporting means such as a pair of fingers projecting from the bottom of the cavity.
