How to accurately control the temperature of the billet induction heating furnace?

Two-point temperature measurement method is adopted. In order to ensure the precise control of the temperature of the steel billet and continuous casting billet during the heating process, an infrared thermometer is generally installed at the inlet and outlet. In addition, in order to make up for the time difference of the temperature measurement by the thermometer and improve the control sensitivity, a hot body detection device is installed at the entrance and exit of each group of furnaces to make the heating furnace maintain low power and high power switching more sensitive and reliable when there are no materials and materials. .
