Abstract

En el funcionamiento de un horno de arco eléctrico de corriente alterna (1) que comprende al menos un electrodo (3a, 3b, 3c) para generar una masa fundida se miden oscilaciones en una pared (2a) de un recipiente de horno (2), por lo que se determina una altura de escoria (Hrel) de la masa fundida. Una reacción rápida con respecto al cambio de la altura de escoria se hace posible al adaptar la longitud de arco eléctrico del al menos un electrodo (3a, 3b, 3c) en caso de desviaciones de un valor real (A, B, C) determinado de la altura de escoria (Hrel) con respecto a un valor deseado (S).
