Product introduction
The working principle of thermocouples is based on the Seebeck effect. It is mainly used to measure the temperature of molten steel and high temperature molten metal. Temperature is the lifeline of steelmaking, if the temperature control is not good, not only can not make good steel but also a great waste of resources. Rapid temperature measurement thermocouples are used in large, medium and small steel mills, for the measurement of liquid steel temperature in front of the furnace, after the furnace and large, medium and small steel packages, with fast response and high measurement rate

Thermocouples produced at present are mainly divided into three categories
1, the Chinese standard type 602 thermocouple: the cost is low, but all are one-time, can only be used once. Mainly sold to domestic steel mills.
2, German standard 604 thermocouple: reasonable structure, high cost, higher precision than domestic 602. Mainly exported to Russia, Pakistan, Africa, Southeast Asia and other countries.
3, Japan and South Korea standard type 0 H-type thermocouple: reasonable structure, high cost, high precision, can be used many times, more for casting, comprehensive use of the lowest cost, and in the use of the process, to prevent the splash of steel, protect the operator's safety is high, and environmental protection. Mainly exported to Japan and Korea.
