The continuous casting billet is heated and heat treated using medium frequency induction heating equipment. Its temperature detection, adjustment and control system is as follows:
(1) The surface temperature of the continuous casting billet is detected using a fixed-point infrared detection device, which can accurately detect the temperature of the continuous casting billet when it is pulled out into the conveyor track, the temperature before entering the induction heater, and the temperature of the billet when the induction coil exits.
(2) Any deviation of the temperature control system from the predetermined temperature point will generate a signal proportional to the deviation, which is input to the proportional control unit and amplified, and the amplified signal is input to the PID regulator, After calculation, it is output to the temperature regulator of the medium frequency induction heating equipment to maintain the optimal power point at a constant temperature. Therefore, any temperature change will cause a small amount of power compensation to eliminate errors, and ultimately meet the set temperature requirements.
This article briefly introduces the temperature detection, adjustment and control system of continuous casting billet during induction heating. I hope it can help you. If you don't understand anything, you can read more books on heat treatment. I believe you will gain a lot.
