Electroslag Remelting Process and Melting Vessel

A method for electro-slag remelting of metals or metal alloys in a melting vessel having at least one inner wall and a melting chamber bounded by the inner wall so that there is a boundary surface between the inner wall and the melting chamber,

• wherein the melting vessel has measuring devices for measuring the temperature and the measuring devices are arranged in at least two measuring groups,
• wherein the measuring devices within a measuring group each have substantially a same distance to the boundary surface between the inner wall and the melting chamber,
• the distance to the boundary surface between the inner wall and the melting chamber differs between the measuring devices of different measuring groups,
• and measuring devices within the same measuring group are arranged at different heights,
• comprising the steps:
• A. providing in the melting vessel at least one electrode of the metal or metal alloy to be melted,
• B. providing slag in the melting vessel,
• C. melting the electrode so that the molten metal or metal alloy passes through a slag zone and solidifies into an ingot,
• wherein a heat balance is established, continuously, by the information obtained via the measuring devices.
