<p>In order to improve heat transfer efficiency, this heat treatment furnace is equipped with a furnace body (10), a hearth (12), a blowing device (14), a wind-passing member (16), a heating device (18), and shelves (20). The furnace body (10) has openings (36) equipped with doors. The wind-passing member (16) has a tubular part and wind-guiding parts. The tubular part has an inlet and shelf-facing outflow ports. Wind flows in from the inlet. The shelf-facing outflow ports face the shelves (20). The wind flows out from the shelf-facing outflow ports. The wind-guiding parts are attached to the tubular part. The wind-guiding parts block a portion of the wind flowing along the inner circumferential surface of the tubular part, and guide this portion of the wind toward the shelf-facing outflow ports.</p> |
