In order to master the flow and heat transfer mechanism of the molten pool of the arc furnace with three electrodes under the action of electromagnetic stirring, the electromagnetic field, flow field and temperature field in the molten pool were simulated and analyzed by using the multi-physical field coupling simulation model, and the simulation method was verified by combining the test results. The results show that the maximum values of magnetic induction intensity, electromagnetic force and Joule heat density in the molten pool occur in the electrode area, which is the main reason why the highest temperature in the area is near the electrode in the molten pool; After the electromagnetic force is applied, the local velocity of the melt near the furnace wall increases, which facilitates the corrosion of the high-temperature melt to the wall. The temperature field calculated by simulation is in good agreement with the test results, and the maximum error is not more than 13.66%, which proves the reliability of the simulation method.
