Process for the electro-slag refining of metals

摘要

When one or more electrodes 3 that melt down during operation in an electro-slag refining furnace is or are melting down, the melting process can be influenced by blowing a gas such as argon into the molten slag. For this purpose, the gas is blown in in the form of a beam directed towards a part of the consumable electrode that is below the surface of the molten slag. This produces a molten slag stream that flows along the consumable electrode, accelerating the melting process of this electrode. The process according to the invention makes it possible to eliminate the unequal melting of two or more consumable electrodes.
