Abstract

The electrode is at the end of a rotary shaft mounted in a pivot bearing in the top of the furnace, so that the shaft axis can be adjusted to various inclinations to the vertical axis of the crucible and the shaft can also slide axially to and fro through the bearing. With the axis of rotation at about 20 degrees to the vertical during melting, the arc wear spreads evenly around the surfaces of the electrode which is thus more durable used for melting Nb, Mo, W, Zr, Ti etc.
