Results are given for laboratory research making it possible to describe identical processes in industrial direct current arc furnaces. On the basis of studying the dependence of iron specific evaporation rate in the anode spot zone on current density and time, an expression is obtained making it possible to evaluate the evaporation rate in the anode spot zone in these furnaces of any capacity. It is based on an analytical relationship of permissible current density on electrode diameter over a broad range of change.
