Abstract:

A molten metal sampling device for immersion into and sampling of a molten metal includes a sample chamber defined by a mold body formed of heat resistant materials encased in a sand-resin body. At least one fill tube is interconnected with the sample chamber for introduction of molten metal. An air outlet passage is provided for egress of air from the chamber. An annular sleeve of heat resistant inorganic material surrounds the outlet passage, the sleeve being adapted to receive a support tube for supporting the sampling device during use. An elongated retaining strip, preferably a wire formed of a heat resistant metal, is affixed to the mold body and extends over the sleeve, thereby anchoring the sleeve to the mold body. Preferably, a central portion of the wire is affixed to the mold body and opposite ends extend through the sleeve and over an end of the sleeve. Preferably, a metal clamping bracket is affixed to the mold body and embedded in the sand-resin body with the wire extending around a portion of the bracket.
