Abstract

The Industrial Solutions and Services (I&S) Group and the Corporate Technology (CT) department of Siemens AG have developed a new method of measuring the changes in the level of foaming slag in arc furnaces over time and in the various parts of the furnace. The method is based on the measurement of structure-borne noise at the furnace shell. The signals picked up at several measuring points enable spatial mapping of the foaming slag around the electrode and panel. Series of tests carried out on a 70-tonne arc furnace of Lech-Stahlwerke GmbH (LSW) showed a very high match with visually determined levels of slag. With the help of the new measuring method, the plant controller will be able to meter the nutty slack and the oxygen - the foaming agents - in such a way that baring of the arcs will largely be avoided. This reduces electrode wear, improves the power intake in the arc furnaces and increases productivity.
