FIELD: electrical engineering.
SUBSTANCE: subject-matter of the method involves switching on of each furnace in the group with a certain delay in time, and namely, start-up of the ready to launch electric arc furnace when melting period of the previous furnace is over in start-up sequence.
EFFECT: reduction of specific energy consumption, increase in efficiency of the group of electric arc furnaces and minimisation of their negative impact on supply mains.
