Abstract

In an electroslag furnace in which the part of the electrode below the slag is melted by a local supply frequency current of >=10 kA, passing between the electrode and the furnace wall, and which is taken onto a transformer whose primary winding is connected to the supply via an a.c. regulator, pref. a section of the circuit comprises an array of condensers connected in series.
