The vertical magnetic induction heating equipment uses solid MOSFET/IGBT power supply, PLC+HMI and high precision thermometer to realize the closed loop control of temperature / speed. It is suitable for the light annealing of copper tube, aluminum tube and copper aluminum composite pipe. The on-line annealing method is combined with the tube production process, and the new pipe can be produced. The heating speed is fast, the efficiency is high, and the energy saving effect is remarkable.
