“…High-power induction cooker was based on the induction heating principle: When a high frequency current flows through a conductor, the space around it simultaneously generates an alternating magnetic field, which will generate skin effect on the target conduction device, and induct eddy currents flowing mostly on the surface of the conductor. Finally, the inducted eddy currents will heat the target device [1][2][3].…”

In this paper, based on the principle of induction heating and eddy current fields working, the equivalent circuit model of induction cooker heating was proposed and analyzed. By using the finite element numerical analysis software, the optimization design and model simulations of induction cooker were implemented. Finally, a new design of induction cooker with the uniform heating-coil was proposed, and the magnetic circuit modeling and simulation of new type induction cooker heating was carried out, the eddy current loss density distribution in the common wire coil and the improved wire coil was separately calculated and compared. The results shown the new wire coil had higher energy efficiency and more uniform heating characteristics, which provided a reference for the future optimization design and development of induction cooker.

“…So far, many temperature and electromagnetic fields of conventional spiral coil induction heating have been investigated using finite element method [9][10][11][12][13][14][15][16]. However, analytical or numerical studies about rolls temperature in induction heating by unconventional coils have not been reported.…”

Hot-roller warm rolling process is expected to achieve a breakthrough in solving the problem of high quality rolling for difficult deformed metals. In this paper roll surface induction heating was studied based on the finite element theory of electromagnetic-thermal coupling and experiment. The law of temperature field for a static roll in induction heating process was analyzed by FEM. The results show that roll surface temperature can achieve 721 at 48s under 20000Hz power frequency, 350×10 4 A/m 2 current density, due to the skin effect on roll surface. Using a special induction coil in the laboratory, an experiment of roll induction heating was carried out with the same process parameters. The calculated results of temperature on roll surface agree well with the measured value.
