Abstract In order to study the characteristics of temperature field distribution during electromagnetic induction heating process of casting billet. Based on the actual process parameters, an induction heating device for casting billet was designed. The numerical simulation method was used to simulate the induction heating process of casting billet with dimensions of 200 mm×1 800 mm×10 m. According to the simulation results, the influences of frequency, transmission speed, power and energy consumption on the heating effect were analyzed. The simulation results show that it is more advantageous to use the medium frequency 800 Hz to 1 000 Hz in the induction heating process of the casting billet. The influence of conveying speed and power consumption of casting billet is also studied. It is considered that the temperature distribution uniformity of casting billet can be improved by increasing conveying speed and adding insulation measures under the condition of equipment. However, due to the influence of the size of the billet itself, too fast transportation speed will lead to uneven heat and affect the uniformity of temperature distribution of the billet. After the casting billet leaves the induction heater to complete heating, adding insulation measures to insulate and transport the casting billet, increasing the conveying speed to 0.1 m/s can reduce the power consumption and improve the uniformity of the overall temperature distribution of the billet.

Key words： Induction heating numerical simulation frequency transfer speed power consumption heat insulation cover
