Abstract

Process for remelting self consumable electrodes using electric current and in a cooled ingot mould, melting causing movements in the liq. bottom of the ingot mould, in which, by using the magnetic field of the melting current, the movement of melting is modified w.r.t. its direction and or intensity.
