Abstract
In a method for operating an arc furnace () with at least one electrode (), a solid material fed to the arc furnace () is melted by an arc () formed by the at least one electrode (). A measurement (MM) for the mass of one part of the solid material arranged on a boundary () of the arc furnace () is determined, and using the determined measurement (MM), a process variable of the arc furnace () is controlled and/or regulated. A method which can reduce the risk of electrode damage caused by metal scraps falling into the treated area is provided.
