Electroslag remelting process and melting vessel

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

• wherein the melting vessel has measuring devices for measuring 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 at least one inner wall and the melting chamber,
• the distance to the boundary surface between the at least one inner wall and the melting chamber differs between the measuring devices of different measuring groups,
• measuring devices within the same measuring group are arranged at different heights, wherein the measuring group which, in comparison with other measuring groups, has the smallest distance to the at least one inner wall/melting chamber boundary surface is arranged approximately in the middle of the at least one inner wag, in the middle between the at least one inner wall/melting chamber boundary surface and the coolant channel;
• and
• comprising the steps of:
• 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 information obtained via the measuring devices.
