What is the operating temperature of the tirîstor in an induction melting furnace?

Temperature: The factory test temperature of the thyristor of the induction melting furnace is 100 °C (junction temperature). Generally, the circulating water temperature of the electric cabinet of the induction melting furnace can be kept below 45 °C to achieve its normal operation. Hand-held infrared thermometers are very useful. Thermometers at 350°C are only a few hundred yuan and are not too expensive. It is used to measure the temperature of the thyristor and the temperature of the radiator of the working power supply, which can detect abnormal points in time and deal with the fault.
