## Abstract

To study the electric furnace melting process of different process parameters (e.g., current frequency, electric current intensity, the insertion depth of the electrode column, and water wall temperature) for each field quantity change and the impact of electric furnace slag conditioning, the mathematical model of the electromagnetic and temperature fields of the slag tempering process in electric furnace was established, and the numerical simulation was analyzed by the ANSYS finite element software. Research results show that current skin effect appears with the increase in current frequency, while the difference between the two ends and the center of the magnetic induction intensity distribution decreases and the joule heat increases. Increasing the strength of the current intensity can reduce the thickness and height of slagging and increase the molten pool height. With the increase of the insertion depth of the electrode column, the electric current flow area in the slag pool increases, the system of the equivalent resistance increases, the current and the system’s extreme temperature decrease, which is conducive to the quenching and tempering process.
