Background technology
In order on tape is vertical, to carry the metal strap that floats on the air cushion, known (DE3026132 A) will be provided with some bellowss, and they are arranged in succession that tape is vertically gone up and its mentioned nozzle area is transverse to tape and vertically extends and comprise the pass nozzle that is distributed on this region surface area.Flow through described pass nozzle and support air cushion against the gas formation one of metal strap, this air cushion is ensured that by the air-flow from the slit-like nozzle these nozzles are transverse to the region surface of vertically extending and limit formation pass nozzle of tape.Because air cushion not only is used for the no touch guiding of metal strap, but also is used for heat conduction, so also must additionally consider for some heat affectings of metal strap hot-cured, the latter, some, the consequence that can cause is that metal strap can center on center longitudinal axis generation arching except other.This means, metal strap apart from the distance of mentioned nozzle area greater than in metal strap longitudinal edge district.Because the described arching of tape must select to support the various situations of air-sprung as follows, so that must guarantee apart from the bellows sufficient distance in the middle region of metal strap, to get rid of any contact in the longitudinal edge district.The needs that need increase distance in middle region cause reducing of the power of delivering, and this then requires to use thin metal strap subsequently, or require to increase by the gas volume flow of mentioned nozzle area.
Summary of the invention
The present invention thereby based on following purpose, promptly provide a kind of device that is used on the above-mentioned type air cushion guiding metal strap, to such an extent as to any delivery power loss that the metal strap of arching can be guided and needn't consider to be caused by the metal strap arching in the no touch mode under heating power influence.
Purpose of the present invention realizes that as follows promptly each mentioned nozzle area spreads all over the basic configuration that section is provided with epirelief, is inclination on the end section at each side place longitudinally being transverse to tape.
Owing to allocate in the epirelief basic configuration of the mentioned nozzle area of metal strap curvature, therefore can guarantee roughly uniform distance between metal strap and the mentioned nozzle area with plain mode, so that can be utilized fully by the air-sprung delivery power that mentioned nozzle area produces, and needn't be worried that the longitudinal edge of tape can touch bellows.The epirelief basic configuration of the mentioned nozzle area that adapts with the curvature of heated metal tape has been guaranteed also that metal strap has vertical substantially air-flow in the longitudinal edge zone and has been filled (flow charging), so that can guarantee favourable on the whole delivery situation.
Be transverse to tape longitudinally metal strap curvature continuous expansion can under the simplest situation by in the end section of nozzle scope, be transverse to tape longitudinally each side place bevelled section be achieved.In order to ensure further the region surface of mentioned nozzle area being allocated in the curvature of heated metal tape, the section of mentioned nozzle area constantly increases gradient at each side place.This state can be achieved by vertical section of the mentioned nozzle area that makes up in class polygon mode.The continuous curvature that is appreciated that mentioned nozzle area is possible.But, this just requires correspondingly to improve manufacturing work.
In the heat treatment of metal strap, remaining all to be provided with the bellows in respective nozzle zone, so that can be from the even heat treatment in metal strap both sides with the metal strap above and below that the no touch mode is guided.Therefore suggestion in the mentioned nozzle area of the metal strap above and below configuration that will guide with the top nozzle area configurations with recessed basic configuration, this shape adapts to down the epirelief basic configuration of mentioned nozzle area.The described recessed basic configuration nature in top nozzle zone has no effect to carrying capacity, but even heat conduction is had remarkable influence, and this point obviously needn't be illustrated in further detail at this.
Description of drawings
Accompanying drawing shows theme of the present invention by way of example.Accompanying drawing shows in schematic form according to device of the present invention, and this device is used for guiding metal strap on the air cushion in each section.
The specific embodiment
According to shown in embodiment, the device that is used to guide metal strap 1 comprises framework 2, this framework for carrying is provided with and forms the bellows 4 of mentioned nozzle area 5 in succession along tape vertical 3.Described mentioned nozzle area 5 is transverse to tape vertical 3 and extends and comprise that pass nozzle 6, the latter are distributed on this region surface area, and gas (as air) send the air cushion that withstands metal strap 1 with formation by their drums.Edge 7 along the mentioned nozzle area 5 that is transverse to vertical 3 extensions of tape has slit shape nozzle 8, and this nozzle 8 defines the scope of pass nozzle 6 and the air cushion that is formed by pass nozzle 6 with its gas jet guarantee.Metal strap 1 longitudinal edge 9 flows out and arrives on the other hand between the return flow line 10 relatively between two row's slit shape nozzles of air-flow one side in each mentioned nozzle area 5 of reflection on the metal strap 1, return flow line 10 is formed between the bellows 4 and owing to following framework surface 11 to be expanded aspect the flow cross from the relative longitudinal edge 9 of metal strap 1 longitudinal center, framework surface 11 is downward-sloping in roof shape mode, thereby to guarantee minimum possible flow velocity and thereby low relatively differential pressure.
Opposite with some common mentioned nozzle area, mentioned nozzle area 5 according to the present invention is provided with the epirelief basic configuration, this shape is adjustable to be assigned in the curvature of heated metal tape 1, so that guarantee the distance that is consistent basically on the strip width between metal strap 1 and the nozzle surface 5.Embodiment as shown in the figure, the epirelief basic configuration of bellows 4 is that each the vertical section 13 by region surface is achieved, these sections are downward-sloping more and more biglyyer and form a polygon mode since a centre portion 12, so that can allocate the continuous curvature of bending metals tape with simple member fully.Because this allotment, can obtain good delivery situation and do not jeopardize the no touch guiding of metal strap 1 on the air cushion of mentioned nozzle area 5.
Even heat treatment both needs at the metal strap downside also in the mentioned nozzle area of upside because metal strap 1 is from both sides, so, also can be provided with and allocate in metal strap 1 curvature and be provided with the mentioned nozzle area 5 of corresponding recessed basic configuration so be arranged on bellows 14 that metal strap 1 top and with dashed lines indicate, so that on strip width, can keep roughly the same apart from the distance of metal strap 1.
