摘要：
The finite element analysis software ANSYS was employed to simulate and analyze the electromagnetic induction heating process in the hot metal gas forming process. A finite element model of temperature field coupled with electromagnetic field had been established based on induction heating theory including Maxwell equations and temperature differential equation. Simulation results showed that with the increase of current frequency of electromagnetic induction coil, under the same heating time, temperature rising rate of steel tube increased continuously, and the final temperature was raised further. With the increase of the current density of electromagnetic induction coil, under the same heating time and current frequency of electromagnetic induction coil, temperature rising rate of steel tube increased continuously, heating efficiency was improved effectively, and the final temperature was raised gradually. With increase of interval space between steel tube and electromagnetic induction coil, temperature of both outside and inner surfaces decreased gradually. The decreasing trend of outside surface temperature became gentler and gentler, while the decreasing trend of inner surface temperature became sharper and sharper. © 2017, Materials Review Magazine.
