Molten metal bath temperature sensor and sampler

Molten metal sampling apparatus comprising a body having two sections, means rigidly interconnecting said sections, said means including at least one metal plate which also defines at least one wall of a sampling chamber located between said sections, another wall of said sampling chamber being defined by a refractory surface, a temperature sensing element within said sampling chamber and supported by one of said body sections, said temperature sensing element extending through a hole in a chill plate positioned to constitute one end wall of the sampling chamber, and means defining an entry into said chamber.

Apparatus comprising a support having an immersion end, a molten metal sampler supported by said immersion end, said sampler including two body sections, two metal plates extending between and interconnecting said sections into a rigid unit, intermediate portions of said plates defining two walls of a sampling chamber, refractory surfaces defining the remaining walls of said chamber, means defining an inlet to said chamber, and a temperature sensing unit within said chamber with its temperature sensing portion being generally along the center line of said chamber.

Molten metal sampling apparatus comprising first and second spaced body sections each having a portion which is cylindrical, each body section having a rectangular boss, said bosses extending towards each other, a plurality of plates, each plate having its opposite ends overlying one surface on said bosses, said plates cooperating to form a rectangular sampling chamber, means to facilitate discharge of gasses from said sampling chamber as a sample of molten metal enters the chamber, and means defining an entry into said sampling chamber.

Molten metal sampling apparatus comprising a support tube having an immersion end, a sampler supported by said immersion end of said tube, said sampler including at least one refractory body and a sampling chamber, an entry passage for permitting a molten sample to enter said chamber, said passage being coaxial with said tube, means for permitting discharge of gasses from within said chamber as said chamber becomes filled with molten metal, a thermocouple within said chamber and having its hot junction generally along the longitudinal axis of the chamber, said chamber being rectangular in section, oppositely disposed walls of said chamber being metal plates having a thickness sufficiently great with respect to the volume of the sample so that the metal plates do not weld to the sample as the sample cools, a chill plate defining an end of the chamber remote from said entry into the chamber, said chill plate having a hole through which legs of the thermocouple extend, an electrical connector coupled to said thermocouple.
