主　　题：longitudinal flux induction heating numerical simulation magnetic flux leakage 

摘      要：A three-dimensional electromagnetic thermal coupled model of a 45#steel strip during longitudinal magnetic flux induction heating was established in this *** influence of different power levels,frequencies,and electromagnetic shielding on the magnetic induction intensity and the heating of parts of different materials around the inductor was analyzed by calculating the magnetic induction intensity around the longitudinal flux induction heater under different *** results show that leakage flux can be reduced up to 49%by electromagnetic *** higher the frequency,the greater the electromagnetic shielding effect,and the lower the magnetic leakage around the ***,the higher the power,the greater the magnetic induction around the *** adding electromagnetic shielding to reduce magnetic leakage of the inductor and replacing the metal part material around the inductor with stainless steel,the heat generation of the parts around the inductor can be greatly reduced.
