Method and apparatus for adjusting electrode isotherms within electro-slag remelting

Image Number 3 for United States Patent #4919712.

A process and apparatus for electro-slag remelting including a cooling medium directed towards the electrode surface adjacent its entry into the slag layer. The cooling medium retards the melting of the electrode periphery within the slage so as to form a concave surface at the electrode tip, such that the molten metal from the electrode tip moves from the center of the electrode toward the outer periphery. The remelting of the electrode in this manner resulting in a shallower molten metal pool below the slag layer and a higher current density in the slag. The invention further redistributes the heat generated in the slag layer from the center towards the outer edge of the molten metal pool progressively formed within the mould and results in an improved smoothness on the surface of the ingot.
