How does the induction heating furnace measure the temperature?
The induction heating furnace heats the metal through the principle of electromagnetic induction, so some people also call it non-contact heating. The metal blank moves in the induction coil of the induction heating furnace, and it is inconvenient to use the thermocouple contact type temperature measurement. Therefore, in the forging industry, the temperature measurement of the induction heating furnace generally uses infrared temperature measurement, and the position is placed at the exit of the inductor. Used to measure the heating temperature of metal blanks. Infrared temperature measurement is generally equipped with a three-sorting device, that is, the temperature is qualified and passed, and the temperature is too high or too low to be transported to different material frames.
