| 摘要 |
The invention relates to a hardening furnace, in particular for sheets of glass (2) and the like. In the furnace, the glass sheets (2) are sustained and transported by a conveyor plane (1) of the roller type above and beneath which plane an upper radiating surface (3) and a lower radiating surface (4) are arranged. The upper radiating surface (3) is composed of a plurality of longitudinal strips (31) arranged side-by-side and parallel to the movement direction of the plane (1), while the lower radiating surface (4) is constituted by a plurality of transversal strips (41) arranged transversally to the said movement direction. Each of the strips (31 and 41) is separated from the contiguous strips and represents the lower and upper walls of chambers (32 and 42) separated one from the other. In each said chamber (32 and 42) there is a device which confers regulatable thermal energy, for example, a radiating tube (15).
