Abstract
A water cooled wall element for at least partially replacing the casing of refractory material in melting furnaces, especially electric arc furnaces for melting steel, above the bath of molten material in the furnace comprises a plurality of parallel, horizontally extending and vertically superimposed tubes abutting against each other, a cooling water inlet connected to the lowermost of the superimposed tubes, a cooling water outlet connected to the uppermost tube, and return bends connecting the ends of proximal tubes to each other so that the cooling water will flow from the cooling water inlet through the plurality of superimposed tubes to the cooling water outlet, wherein elongated substantially uninterrupted protrusions are provided on each of the tubes and extending in the longitudinal direction thereof on that surface of the wall element which is directed toward the interior of the surface to increase adhesion of an insulating layer of refractory material to be applied to the inner surface of the wall element.
