Abstract

In a method for determining a dividedness and/or position of a batch material existing essentially in the solid phase in an arc furnace having a furnace vessel, acoustic signals are generated by an arc discharge between an electrode and the batch material. The acoustic signals reflected and/or transmitted through by the batch material are measured by acoustic sensors, wherein at least one acoustic sensor is provided per segment of the furnace vessel subdivided into a plurality of segments, and wherein the dividedness and/or position of the batch material in the arc furnace is determined by evaluating the measured acoustic signals.
