Electrode arrangement for dc electrothermal furnaces - having four electrode arranged in a square with polarity changer connections

摘要

Electrode arrangement for d.c. electrothermal reduction furnace has electrodes mounted above it. These are connected in pairs as anodes and cathodes mounted in series to the output of a d.c. rectifier with a switching arrangement. The electrodes are mounted on the 4 corners of a square and inserted through a hole in the top. Each pair of electrodes are connected to the poles of the d.c. source and have a pole inverter connector connected across them. Used in electrothermal reduction furnaces and gives a d.c. arrangement comparable to that on an a.c. furnace.
