- the outer skin consists of a gas-tight welded sheet steel housing 30.
- On the inner wall there are holding pins 31 for layers 32 of heat insulation material, for. B. attached by welding.
- These layers 32 applied to the outer wall 30 consist of fibers with a high SiO 2 content, which have good mechanical properties, but tend to decay at high temperatures above approximately 800 ° C. and in a hydrogen atmosphere, since SiO 2 is reduced to SiO.
- a film 33 made of a highly heat-resistant material e.g. B. placed a nickel-chromium alloy.
- a further film 33 made of highly heat-resistant material is used for covering the relatively small-sized sheet metal elements 35 as mechanical protection, preferably made of perforated sheet metal. All layers are held by platelets 36 on the pins 31 are attached. To easily change the outer fiber layers too can, it is appropriate to such platelets, preferably made of thin sheet metal manufactured, also to be applied as an intermediate fastening to the first film layer.
- Impingement jets of the heating or cooling fluid in particular a gas, e.g. pure Hydrogen or a hydrogen / nitrogen mixture with a high hydrogen content, blow, which exerts a flat force on the tape, which is similar a spring increases with decreasing distance between band 1 and nozzle field; this leads to a position stabilizing effect on the tape, the size this stabilizing force from the dynamic pressure of the blowing fluid in the Jet exit depends on the impact jets.
- a gas e.g. pure Hydrogen or a hydrogen / nitrogen mixture with a high hydrogen content
- the distance between the arranged on both sides of the belt 1 Nozzle fields in the heat treatment part is heating 4 in the two areas and cooling 5 are essentially constant, which means that the Distance change is a maximum of ⁇ 10%.
- a suitable nozzle system for achieving the desired effect is described in the EP 0 864 518 B1 and has successive ones in the tape running direction Nozzle surfaces with nozzle openings from round holes and / or slot nozzles, where the width of the nozzle surfaces - measured parallel to the belt running direction - over the Width of the nozzle field - measured perpendicular to the strip running direction - changes.
- the Nozzle surfaces are at least partially circumferential by slot nozzles edged.
- This stabilizing nozzle system can be designed and operated in such a way that the belt 1 through the nozzle system also stabilizes transverse to the belt run experiences, this transverse stabilizing effect in the area of the belt run with - of considered above - concave curvature is particularly pronounced.
- Any suitable fluid can be used as the barrier fluid for the region 12, wherein preferably working with a liquid.
