<p>A prebaked carbon electrode intended to be used in electric arc furnaces and, more particularly, in submerged arc furnaces such as the furnaces normally used for the production of silicon metal, phosphorus, ferro-alloys, and other metals, having a body and one or more joints to create an electrode column, the electrode having a composite construction comprising an outer portion or "rind" made from a first material and an inner portion or "core" made from a second material, wherein for example the first material is an an electrographite based material and the second material is an anthracite based material, the electrode being obtained by extrusion, vibration, molding or by any other suitable process known in the art. Quite generally, both the "rind" and the "core" can consist of any type of carbonaceous material.</p> |
