Temperature-resistant materials as protective coat for the metal shaft of combination electrodes for the electric steel production, constituting a compound material comprising a carbon share, which contains graphitic structural elements, and a share with at least one ceramic component. The protective elements, which are made of these materials, are characterized by long service times, little susceptibility to unwanted adhesive matter, and good emergency running properties.

Protective coating of temperature resistant materials for the metal

An electrode for electric arc furnaces, comprising an upper, metallic, water-cooled section and a lower section of consumable material, such as graphite, is held in its given position by means of an electrode support arm 1,2. The connection elements for electric power and liquid coolant 12, 6, 25 are integrated in the electrode support arm and are designed as plug connections.
