Abstract: A heat treatment device for a thermal treatment of a workpiece is provided with a housing that houses a chamber for accommodating the workpiece for the thermal treatment. A first roller supports the workpiece and moves the workpiece in a moving direction. A first brush seal is provided, wherein the first roller and the first brush seal are arranged relative to each other such that a first side of the workpiece contacts the first roller and a second side of the workpiece that is opposed to the first side contacts the first brush seal such that the first roller and the first brush seal then seal at least a first section of the chamber from a second section of the chamber.

Abstract: The invention relates to a heat treatment device (100) for thermally treating a workpiece (101), in particular a strip-shaped workpiece (101). The heat treatment device (100) comprises a housing (102), which surrounds a chamber (103), in which the workpiece (101) can be positioned for carrying out a thermal treatment. The workpiece (101) is supported by a first roller (110) and can be moved along the direction of travel (105). The first roller (110) and a first brush seal (111) are arranged in relation to one another in such a way that a first side of the workpiece (101) is in contact with the first roller (110) and a second side of the workpiece (101), which is opposite the first side, is in contact with the first brush seal (111), such that, via the roller (110) and the first brush seal (111), at least one first section (I) of the chamber (103) is sealed in relation to a second section (II) of the chamber (103).

Abstract: An apparatus is described for bracing of sheet-metal joints (1) in a high-temperature annealing furnace having at least one carrier (2), which frontally receives a sheet-metal joint (1) and has a central axial passage opening (6), on which a support pipe (5), which axially penetrates the sheet-metal joint (1), having a carrier (2) for receiving a further sheet-metal joint (1) can optionally be placed in a load-bearing manner. In order to provide advantageous heating conditions, it is proposed that the carrier (2) has a ring body (7) forming the passage opening (6), having radially protruding carrier arms (8) distributed around the circumference.
