Abstract
In a method for determining a dividedness and/or position of a batch material (7) existing essentially in the solid phase in an arc furnace (1) having a furnace vessel (2), acoustic signals (N.sub.e, N.sub.g, N.sub.d) are generated by an arc discharge (6) between an electrode (3a, 3b, 3c) and the batch material (7). The acoustic signals (N.sub.e, N.sub.g, N.sub.d) reflected and/or transmitted through by the batch material (7) are measured by acoustic sensors (5a, 5b, 5c, 5e, 5g, 5h, 5s, 5t), wherein at least one acoustic sensor (5a, 5b, 5c, 5e, 5g, 5h, 5s, 5t) is provided per segment (S.sub.n) of the furnace vessel (2) subdivided into a plurality of segments (S.sub.n), and wherein the dividedness and/or position of the batch material (7) in the arc furnace (1) is determined by evaluating the measured acoustic signals (N.sub.e, N.sub.g, N.sub.d).
