Abstract
An electroslag remelting furnace with a power connection at the base and a coaxial conductor to eliminate the deleterious effects of magnetic fields upon the pool of molten metal. The furnace may have a vertically moveable crucible, and also a top supported inner mold to form a hollow ingot, for containing the molten portions of the metal as the ingot is formed. The upper portions of the annulus between an inner and outer mold can be greater in width than the width of the lower portion of the annulus to permit increased spacing between the electrodes and the walls of the molds or to permit the use of electrodes of a larger diameter than the width of the lower portion of the annulus.
