Beschreibung
Zusammenfassung:	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.6 cl, 3 dwg В способе эксплуатации электродуговой печи (2), работающей с переменным напряжением, а также в правильной установке с электродуговой печью (2), эксплуатируемой согласно этому способу, регистрируют возникающий в стенке электродуговой печи (2) сигнал (S) корпусного шума, из которого вычисляют параметр К, характеризующий свойства фликер-эффекта электродуговой печи (2), и с помощью этого вычисленного параметра К управляют по меньшей мере одним параметром процесса электродуговой печи (2). Изобретение обеспечивает возможность автоматически учитывать при управлении параметрами процесса электродуговой печи возникновение фликер-эффектов. 2 н. и 4 з.п. ф-лы, 3 ил.
