Beschreibung
Zusammenfassung:	A horizontal heat treatment device is configured so that the leakage of gas within seal chambers to the outside can be prevented even if the amount of gas for an air curtain is reduced. A horizontal heat treatment device is configured so as to continuously subject an untreated continuous flat object to heat treatment while horizontally transferring the untreated object within a heat treatment chamber. Seal chambers (4) are respectively interconnected to the untreated-object loading opening and treated-object unloading opening of the heat treatment chamber (2). A passage having a rectangular cross-sectional shape is connected to an opening of each of the seal chambers (4), the opening being located on the side opposite the heat treatment chamber (2). The untreated-object loading opening of the passage interconnected to the untreated-object loading opening of the seal chamber and the treated-object unloading opening of the passage interconnected to the treated-object unloading opening of the seal chamber are respectively the untreated-object loading opening and treated-object unloading opening of the heat treatment device. A pair of gas ejection nozzles (10a, 10b) are provided at upper and lower positions of the passages. The nozzles (10a, 10b) eject gas in specific directions, and the gas ejection openings of the nozzles (10a, 10b) have a specific shape, a direction, and a length. The distance (d)(mm) between the gas ejection openings and the untreated-object loading opening or the treated-object unloading opening of the heat treatment device and the passage height (Dn) satisfy 2 ‰¤d < 0.75Dn.
