Abstract

A box-shaped shallow, water-cooled element of steel plate for the construction of a wall portion of a melting furnace above the melt in the furnace, has a front wall adapted to face the interior of said furnace. This front wall is provided with a plurality of recesses of equal cross-section equally spaced from each other in the form of elongated grooves or bores to facilitate adhesion of a layer of refractory material to be applied thereto, wherein the recesses are machined in the surface of the front wall adapted to be directed to the interior of the furnace in such a manner that the area of recesses at this surface is smaller than the area of the remaining non-machined surface to thus enhance heat conduction from the interior of the furnace to the cooling water passing through the wall element and to prevent damage of the front wall when the protective layer is missing completely or in part.
