摘要
The present invention is: a horizontal heat treatment apparatus for continuously heat-treating by moving a continuous flat workpiece to be treated (carbon-fiber-precursor fiber bundles) back and forth in the horizontal direction on multiple levels inside a heat treatment chamber, the horizontal heat treatment apparatus being characterized by being provided with a sealing chamber (4) which is continuous from the entrance (6) side of the heat treatment chamber (2) in to which the workpiece to be treated is conveyed to the exit (6') side thereof and that is vertically delimited by partition plates making a heat transfer zone in which 2 to 4 levels of the workpiece are transferred, among which the temperature of the workpiece transferred in a lower level is higher than the temperature of the workpiece transferred in a higher level. As a result, the horizontal heat treatment apparatus completely prevents leakage of poisonous gas produced in the heat treatment chamber, and effectively prevents energy loss.
