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.
