本発明は、ストリップ浮上支持装置のステアリング装置
に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a steering device for a strip floating support device.
ストリップ浮上支持装置を、第３図（ハ））と同図のＡ
−Ａ断面図である第３図（Ｃ）によシ説明する。The strip floating support device is shown in Figure 3 (C)) and A in the same figure.
This will be explained with reference to FIG. 3(C), which is a sectional view taken along line A.

, the fluid (e.g. air) is introduced into the internal space 4 of the box 2 fixed on the stationary side 3 through the pipe 6, and the hole (or slit)
By injecting this fluid from 5 towards the strip 1, the strip 1 is supported floatingly. These 2 to 60 sections are used for a straight strip running path, and a plurality of them are installed at appropriate (for example, 5 to 10 m) intervals.

。A major feature of floating and supporting a strip using the strip floating support device shown in Figure 3 is that the strip is not damaged during running (transportation), compared to when the strip is supported low. At the same time,
The resistance in the strip running direction (slip/fluid shear resistance) of the supporting portion is extremely small), and the energy loss for conveyance is negligibly small.
後者の抵抗が小さくなるという特徴は、ストリップ走行
直角方向（スＦリップ巾方向）Ｋついても同じである。The latter characteristic of reduced resistance is also the same in the direction perpendicular to the strip running direction (slip width direction) K.
このため、ストリップ浮上支持装置の水平度が保たれて
おれば、ステアリングの為の力も小さくてよいし、特に
問題ないが、ス）リップ浮上支持装置の水平度が保たれ
るという保証がない。Therefore, if the horizontality of the strip floating support device is maintained, the steering force may be small and there is no particular problem, but there is no guarantee that the horizontality of the strip floating support device will be maintained.

リップが支持部を外れてしまう。For example, it is best to consider that the horizontality of the support lip floating support device may be disturbed due to thermal deformation of the entire device, uneven settlement of the foundation of the entire device, etc. Now, Figure 3 (
As shown in d), if the horizontality is off by θ in the direction perpendicular to the strip running, the strip's own weight (one span) FG
Strip lateral force F from K! = F, daθ acts. For example, if a strip with a width of 1500 m per day is supported horizontally with a span of 6 m, and if θ = 2°, then F will be 2.
5 to 9f (1 span) (Figure 3), the length of strip 1 will be more than 40m, so F will become larger as time goes on). If 50 strip floating support devices are installed, the total length will be 180 m, and in the worst case, a distributed load of 2.5 kgf/6 m will act on this line as a lateral force during F3. Although the force itself is not extremely large, the deformation of the 180 m strip becomes large and the strip comes off the support.
