Abstract: Aiming at the problem of energy loss in the electromagnetic induction heating device of magnesium reduction tank, the influence factors and the relationship between the energy transfer, the heat loss and the resistance loss of the excitation coil were studied. A new design method of electromagnetic induction heating device for high temperature excitation coil magnesium reduction tank was put forward. The coupling model of electromagnetic system and heat transfer system was established by using electromagnetic working module in CST software. And the heat loss of the reduction system and the resistance loss of the excitation coil were simulated by this model. The results indicate that the total loss of the magnesium reduction system is minimal when the excitation coil allows a maximum working temperature of 900 ℃. The method reduces the total loss of the magnesium reduction system and improves the energy efficiency. It can provide a new idea for the design of the electromagnetic induction heating device for the magnesium reduction tank.
