Abstract
The results of mathematical modeling of electrical and thermal processes in a graphitized cored (composite) electrode for alternating current arc steelmaking furnaces are presented. A comparison is made with similar processes in a monolithic electrode and the regularities of these processes are determined. The calculations are performed using the developed mathematical model based on the finite element method with the introduction of a number of simplifications and assumptions. The distribution of current density, electric potential, magnetic induction and temperature in the electrode is studied, which allows predicting the operation of cored electrodes in arc furnaces. The estimated results of the calculations show that cored electrodes, when operating on alternating current, similar to direct current operation, are also characterized by lower electrical losses and heating temperatures compared to monolithic electrodes, which makes them more energy and resource efficient.
Keywords: cored (composite) electrodes, monolithic electrodes, arc steelmaking furnaces, alternating current, current density distribution, electric potential distribution, temperature distribution, energy efficiency, resource efficiency
