  • Device for measuring temperature in molten metal
    Patent number: 9182291
    Abstract: A device for measuring the temperature in molten metals contains a thermocouple arranged in a ceramic tube that is closed on one side, and has an external protective body that surrounds the tube, forming an annular space between the outer surface of the tube and the inner surface of the protective body. The protective body is formed of a mixture containing 75 to 90% by weight aluminum oxide, 2 to 10% by weight silicon oxide, 7 to 15% by weight graphite, 0.1 to 1% by weight Fe2O3, 0.1 to 1% by weight (K2O+Na2O), and 0.1 to 1% by weight MgO.
    Type: Grant
