Abstract

Metal plates having a height to width ratio of 2 to 3:1, which are used for thermal protection of the shells of shaft furnaces for smelting, are made up of individual bars, of which the width exceeds the height. The surfaces of the bars facing the furnace shell are provided with recesses into which U-shaped coolant-conveying tubes are fitted. A thermally conductive material is placed in the recesses to improve heat transfer from the plates to the coolant flowing inside the tubes. Elements are located between the recesses for attaching the bars to the tubes. Further elements are welded to the tubes so that they can be secured to the furnace shell. Differential thermal expansion in the vertical direction can be taken up without developing the material stresses which occur in one-piece plates. The life of the plates is increased and the time between repairs is extended. The probability of dangerous situations arising is reduced.
