Abstract: A thermal processing furnace for workpieces has a blowing hood in which a nozzle is installed, the nozzle blowing a gas flow to thermally process a workpiece, including a driving mechanism that adjusts a distance between the nozzle and a portion of the workpiece facing the nozzle so that the gas flow blown from the nozzle impinges on workpieces of various dimensions at a desired flow velocity, wherein a plurality of nozzles are arranged as the nozzle along a conveying direction of the workpiece in a zone where the thermal processing is performed, and the driving mechanism adjusts a distance between each of the nozzles and a portion of the workpiece facing the nozzle individually in each of the plurality of nozzles.

Abstract: In a heating furnace 10 where elongate workpieces fed into the heating furnace are sequentially transferred on fixed beams by walking beams from an inlet area to an outlet area, concaves to retain the workpieces are formed at least on the walking beams. A concave in the inlet area for heating the workpieces is increased in width in a transfer direction, while a concave in the outlet area where the heated workpieces are wholly heated to a uniform temperature and retained in position is formed in a corrugated configuration. Despite curving of an elongate workpiece being heat treated as transferred by walking beams in a direction crossing a longitudinal direction of the workpiece, this ensures that the curved workpiece is properly transferred and adequately corrected for the curving.
