Analysis of electromagnetic processes in the induction channel furnace used in the cable industry
A method of calculating electromagnetic processes and energy characteristics of the channel induction furnace to produce copper rod has been proposed. The model of the furnace is based on the equivalent electrical circuit with slowly changing load resistance due to an increase in the temperature pattern. From the results of calculations of reactive power consumed by the furnace at a different temperature pattern was shown that the value of this power at the end of the heating process is reduced by approximately 10 % from the initial value and hence the value of compensating capacitive at the end to be reduced by the same amount.
