ABSTRACT:
In a second horizontal plate (18a) bottoming an atmosphere recovery box (18), there are formed circular holes (21) between blowout pipes (20) adjacent to each other. Each of partition walls (2) positioned above a conveyor (5) includes an upper portion formed from a heat-insulating wall (2a) including a heat-insulative material having a thickness of T, and a lower portion formed from a metallic-plate wall (2b) extending downward from the heat-insulating wall (2a) toward the conveyor (5). The pitch P2of the blowout pipes (20) across the metallic-plate wall (2b) is substantially same as the pitch P1(12 mm) of the blowout pipes (20) disposed inside each of the chambers (R1to R5) and adjacent to each other.
