<p>A continuous heat treatment method for plate-like works capable of intermittently carrying the works through a raising step, a moving step, a stopping step, and a placing step in an apparatus for heat-treating the plate-like works. In the raising step, the works are floated without being moved in the lateral direction by blowing gas from a large number of jetting ports positioned so that the jetting directions thereof are gradually changed to the horizontal side toward the upper side to the lower surfaces of the works. In the moving step, the flow of the blown gas is increased more than that in the raising step to move the works in the lateral direction. Since the works are not laterally moved in raising and placing, the works can be prevented from being damaged by their rubbing against a receiving part.</p> |
