Verfahren zum Betrieb eines Gleichstrom-Lichtbogenofens

摘要

In the case of a direct-current arc furnace having a large-area base contact (3), electromagnetically caused bath movements are influenced by means of an electromagnet (9), which is arranged underneath the vessel base (4), such that the natural flow in the melt bath, which is produced by the current flow in the melt, has its direction reversed. In this way, the stability of the base electrode (3) is considerably increased. The electromagnet (9) is preferably integrated into the electrical supply of the furnace, and is used as a smoothing inductor. ……
