Abstract
A non-splash molten metal sampler has a refractory fiber body which defines a cylindrical mold cavity with sand-resin plugs providing end walls for the cavity. The plugs can be formed in place. The fiber body is easily machined to provide a side entry port and grooves for pin sample tubes and thermocouple wires.
Claims8
A molten metal sampler comprising first wall means defining a generally cylindrical sample cavity, said first wall means being formed from temperature resistant fibers, and second wall means for sealing the ends of said sample cavity, said second wall means comprising molded sand-resin plugs spanning said cavity, said plugs being in sealing contact with said first wall means and a side entry port to introduce molten metal between said plugs, and smooth plates between said sand plugs and spaced to form disc samples with smooth surfaces.
A method of making a molten metal sampler comprising the steps of providing a cylindrical mold body formed from refractory fibers having a mold cavity formed from refractory fiber, providing discs to define walls of the mold cavity, forming a hole in the mold body and injecting a sand-resin mix against a disc to form an end wall for the sample cavity.
