PROCESS AND APPARATUS FOR ELECTRO-SLAG REMELTING METALS AND IN PARTICULAR STEEL

摘要

An apparatus and method for electro-slag-remelting of metals and in particular steel. The electric current flowing through the to be molten electrode changes periodically. The current which is being fed to the apparatus may be either an ordinary alternating current or a three-phase alternating current and is converted into a substantially different current having a base frequency (f) which periodically changes its direction. It is the latter current which supplies the power for remelting the electrode.
