<p>An electrode for electric arc furnaces, in particular for production of iron and steel, comprising a liquid-cooled upper portion, which may be inserted into an electrode holder, a lower portion forming the electrode tip being detachably fastened to the upper portion, which upper portion contains a conduit system for the cooling liquid protected by a fire-proof material, by way of which conduit system the electric current of the arc electrode may also be conducted. Heat conducting projections covered by the fire-proof material are provided on the outer surface of the conduit system facing the furnace chamber, while an electromagnet for producing a magnetic field is disposed in the region of the fastening point of the electrode tip to cause the arc on the electrode tip to move.</p> |
