ABSTRACT:
Electrode for arc furnaces, more particularly for electrosteel production, also using scrap, comprising a detachable top portion (5) of metal and a replaceable bottom portion (6) of material which is consumed, where appropriate only slowly, having substantially cylindrical shape and being interconnected by a screw nipple (1) or the like and the top portion has a liquid cooling device with a header duct (2) and a return duct (3) and an inner part (16) and an outer part (17) of the top portion are constructed so as to be detachable from each other, so that the inner part (16) contains the liquid conducting chamber with header duct and return duct and the outer part (17) surrounds only a portion of the inner part (16). The electrodes have a reliable coolant conducting system, are easy to maintain and can be simply repaired in the event of mechanical damage while minimizing electrode down times.
