FIELD: furnace and plate.
SUBSTANCE: method for operating alternating voltage electric arc furnace (2), as well as correct installation with electric arc furnace (2), operating according to said method, comprises detecting structure-borne sound signal (S) arising at a wall of electric arc furnace (2), from which is calculated parameter K which characterises flicker properties of electric arc furnace (2), and using calculated parameter K, controlling at least one parameter of process of electric arc furnace (2).
EFFECT: invention enables to automatically take into account when controlling process parameters of electric arc furnace occurrence flicker effects.
