<p>HEATING FURNACE FOR ELONGATE MATERIAL A heating furnace for elongate material, more particularly for bars, billets and the like, of light metal, has a furnace tunnel (15), formed of furnace shells (14), for the material (1) to be heated. At least in their center portion, the furnace shells are covered by a thermal protection means which comprises insulating elements (54,56) designed to be removable. The insulating elements (54,56) extend upwardly beyond the furnace shells (14) and define a flue gas passageway (32), of which the furnace tunnel forms an integral part. This provides the heating furnace with a thermal protection means easy to assemble and disassemble which considerably improves the utilization of the energy input for heating. Fig. 1.</p> |
