In general, various types of sheet ovens have been known in the past, in which a sheet is propped up on a wicket and passed through the oven to undergo continuous heat treatment. For example, there is a structure in which a pressure accumulation chamber is installed on both sides of the oven ceiling, and hot air is ejected downward from the pressure accumulation chamber, and the amount of air emitted is reversed and raised at the bottom of the oven to heat the sheet. An oven with a structure that heats the sheet by blowing hot air upward from the pressure accumulating chamber and flowing it from the bottom of the sheet, or an oven with a pressure accumulating chamber on the side wall of the oven and blowing out hot air from many hole nozzles. Some of them have a structure in which the hot air flows from the side of the seat and the hot air is sucked and collected from the opposing side wall.

とができる。 Each sheet 8 to be heat treated is propped up on a wicket 9 and sequentially conveyed into the heat treatment chamber 1 by the drive of the chain conveyor 7. Hot air is sprayed onto each sheet 8 that has entered the heat treatment chamber 1 from both side edges of the sheet 8. That is, elongated gap nozzles 4a, 4b, 4c formed parallel to the sheet conveyance direction are emitted from the pressure accumulation chambers 2a, 2b, 2c disposed on both sides of the chain conveyor 7 in the traveling direction (sheet conveyance direction). Through this, hot air is injected into the side edge space of the sheet 3. At this time, the hot air flows parallel to the sheet 8. Further, the amount of air flowing into each pressure accumulating chamber 2a, 2b, 2c can be adjusted respectively by dampers 5a, 5b, 5c.

ート８の安定化をはかることができる。 In this way, the sheet oven A described above has the pressure accumulation chambers 2 disposed on both sides of the heat treatment chamber 1 in the direction in which the conveyor 7 moves, and is divided into three stages, so that The hot air blown out from the respective pressure accumulating chambers 2 on both sides hits the lower part more evenly than in the past, so that the heating temperature of the sheet 8 can be maintained uniformly. In addition, the sheet 8 can be prevented from swinging by slowing down the speed of the hot air jetted from the gap nozzles 4a, 4b, and 4c on both sides and reducing the occurrence of collision flows between the jets on both sides. . In addition, gap nozzles 4a, 4b,
By causing the jet from 4c to flow parallel to the sheet 8, both side edges of the sheet 8 will constantly move within the jet. Therefore, the sheet 8 does not pass through the boundary between the jets and the sheet 8 can be prevented from swinging, and together with the small collision force of the jets, the sheet 8 can be stably conveyed within the heat treatment chamber 1. be able to. Furthermore, in this embodiment, the damper 5
By adjusting a, 5b, 5c, the gap nozzles 4a, 4
The amount of hot air ejected from b and 4c can be adjusted more delicately, and the aforementioned heating and temperature increase state can be made uniform and the sheet 8 can be stabilized.
