Abstract
A thermocouple assembly for a continuous casting mold. The assembly includes a hollow body one end of which has external pipe threads whereby the hollow body may be sealingly threaded into a threaded cavity provided in the outer surface area of the mold wall. The hollow body is sealed in the water jacket by means of a sleeve received over the hollow body. A seal is placed between the hollow body and the sleeve and a second seal is placed between the water jacket and the hollow body. A constantan thermocouple is received in the hollow body and is maintained in direct contact with the mold by either a compression spring or by being threaded into the mold.
Claims12
A thermocouple assembly for use in a continuous casting mold, said thermocouple assembly comprising:
- an elongated hollow body, one end of said hollow body including pipe threads thereon;
- a thermocouple disposed in said hollow body, said thermocouple including a contacting end extending out of said one threaded end of said hollow body;
- a sleeve disposed around said hollow body;
- a first seal received between said sleeve and said hollow body;
- and
- means in said hollow body for resiliently biasing said thermocouple contacting end out of said threaded end of said hollow body.
A mold for a continuous casting machine, said mold including a wall with a cavity therein, a water cooling jacket having a through aperture aligned with said cavity, and a temperature sensing apparatus including an elongated hollow body, one end of said hollow body having external pipe threads thereon, said cavity including first internal threads for threadedly engaging said one end of said hollow body whereby the interior of said hollow body is sealed from cooling water, said hollow body disposed in said through aperture;
- a thermocouple disposed in said hollow body, one end of said thermocouple extending away from said one end of said hollow body into said cavity and being in direct contact with said mold wall;
- means for maintaining said thermocouple in direct contact with said mold wall;
- and
- means operatively associated with said hollow body for sealing said hollow body in said through aperture and preventing water from escaping from said water jacket whereby said thermocouple is sealed from contact with cooling water.
