ABSTRACT OF THE DISCLOSURE An electric arc melting furnace in the case of which the lateral furnace wall comprises at least one water cooling box made of welded sheet steel and arranged above the melt level and the substantially vertical surface which faces the inside of the furnace, is provided with profile- like projections, which favor the adherence of a refractory protective layer formed on the surface. The wall facing the inside of the furnace of the water cooling boxes has a thickness of at least 15 mm, the projections are constructed as open-topped hollow profile irons, arranged mutually offset in the axial direction of the furnace in such a manner that they catch downwardly dripping, splashed slag. As a refractory protective layer a refractory compositon is employed, which is applied beforehand.
