Abstract: Based on Maxwell′s theory of electromagnetic fields, the electrical conduction equation in slag is obtained. In order to simplify the mathematical calculation of temperature, the turbulent heat conductance coefficient is indicated and calculated. Finally, a software to produce the numerical solution of electric and temperature fields under cylindric coordinates is developed. By this software, the electric potential and temperature can be easily predicted.
