Abstract In order to study the influence of physical properties of billets on the temperature field during induction heating, a coupled finite element model of electromagnetic and heat transfer of moving billets was established, and the influence of a specific physical quantity on the temperature field of billets was studied by single factor analysis method. Then, the influence of the two billets with different physical properties on the temperature field is compared and analyzed. The results show that the influence of relative permeability on cross section temperature is mainly caused by the larger induced current and the shallower yield depth. Under the influence of relative permeability and thermal conductivity, the temperature difference between carbon steel core and surface decreases slightly, while that between stainless steel core and surface increases slightly. In addition, combined with the actual heating process, when multiple physical properties change with temperature, the conductivity and specific heat capacity of carbon steel attenuate the effect of the relative permeability on the rapid rise of surface temperature during heating. The final test data show that the theoretical calculation results are 2.44%-6.97% higher than the actual heating results while the trend of temperature rising is consistent.
