Abstract:
1. A method for producing a molten metal ingot in a water-cooled mold comprising a mold, a bottom plate movable in the mold, a remelt ingot on the bottom plate, a molten bath sump on the remelt ingot, a slag bath on the molten bath sump and a consumable melting electrode contacting the slag bath, comprising the steps of: providing a first current conducting element on the mold and a second current conducting element on the mold; insulating the first current conducting element from the second current conducting element; selectively controlling a feed of melting current to the slag bath by means of at least one of the consumable melting electrode, the bottom plate and the first current conducting element; and removing current from the slag bath by means of the second current conducting element which is insulated from the first current conducting element on the mold.
