Abstract
A carbon electrode, in particular a graphite electrode for producing steel which can be used for electric arc melting furnaces of conventional design. The electrode comprises a metal-containing protective layer, and fusion of the contact jaws of the electrode holder with the metal-containing protective layer is avoided by covering at least part of the electrode surface by a graphite-containing material.
Claims11
In a carbon electrode for an electric furnace, said electrode having a first coating comprising a metal containing composition, and said electrode having upon its surface an area connectable to the jaws of an electrode holder, the improvement therein comprising a second coating upon said first coating, said second coating comprising a graphite containing material, and said second coating covering at least said area on said electrode, whereby fusion of said jaws of said electrode holder to said electrode is prevented.
