下降させあるいは下降した後で上昇させて走行させる。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Fields] For example, in a vertical steel strip heat treatment furnace, the steel strip is raised and then lowered, or lowered and then raised and run.

に関する。The present invention relates to a gas support device for changing the running direction of a strip, which is used when supporting this steel strip using a gas cushion, for example.

易いという問題点がある。[Prior Art] In a typical vertical annealing furnace for steel strips, the steel strip is supported by passing between rolls disposed at the top and bottom of the furnace, and the steel strip is caused to travel by changing its direction. However, this method has problems in that the steel strip tends to be scratched because the rolls rub against it, and the running path of the steel strip tends to meander.

いはストリップに表面疵を発生させる。JP-A No. 63-176435 discloses a strip flotation device for conveying the strip in a non-contact manner, although it is not for changing the running direction, and is characterized in that a substantially upright side plate is installed on the side of the strip movement line. . Although details are not described in this publication, Figures 5 (A) and (B) are examples in which this side plate is used as a gas support device for direction change.
(CB) is a side view, and (CB) is a front view. In this method, the side plate 40
(40') is provided to prevent the strip from meandering, but as will be described later, if the side plate 40 (40') is provided without any special measures, the strip 1

。JP-A-60-138019 is not a device for changing direction, but relates to a floater nozzle for conveying strips in a non-contact manner. In this method, a 7-shaped slit is provided in the width direction in order to float the width end of the strip l. However, as shown in Figure 5(C), this V-shaped slit is a slit formed with the V-bottom facing toward the center of the width of the strip, so it is used for changing the running direction of the strip as described later. However, it is not possible to prevent the strip from meandering.

せるという問題点があった。Also, although it is not mentioned in the prior art, for example, in a vertical heat treatment furnace for steel strips, the rolled steel strips are passed through the steel strips without shape correction, but the steel strips that have not been shape-corrected have an ear wave. Conventional gas support devices for changing direction have a problem in that the gas support device comes into contact with the ear waves and mid-stretches, causing flaws.

The object of the present invention is to provide a gas support device that does not run with a ridge and is capable of supporting a band plate having an ear wave or an elongation in a non-contact manner.

Seal plate 4, 4
' is provided at the top of the arc surface at an elevation angle of 30 to 70 degrees. When the seal plates 4, 4' are provided over the entire length of the arc surface, as will be described later, the wide ends of the strip plate 1 come into contact with the seal plates 4, 4', and the smooth running of the strip plate 1 is prevented. This also causes scratches on the strip 1. The height of the seal plate 4.degree. 4' is not particularly limited, but can be set to 30 to 50 cm.

(B-1) is a side explanatory view of the V-shaped slit 3 side, (B-2
) is an explanatory side view of the V-shaped slit 3' side, and (C) is an explanatory front view. An example will be explained in which the band plate 1 is shifted in the direction of the arrow 11 in FIG. 2(A) due to, for example, non-uniform plate thickness or curling. When the strip plate 1 shifts in the direction of the arrow 11, the entire V-shaped nozzle 3 including the V bottom 3-1 is covered by the strip plate 1.

'-2 is covered by the strip 1. Therefore, the strip plate 1 on the V-shaped nozzle 3 side has ■grooves 3-1 as shown in FIG. 2 (B-1).
The gas flow blown upward from the wall lifts the object upwards.

The plate 1 is tilted on the gas pad surface 2 as shown in FIG. 2(C), but the strip plate 1 moves in the direction of arrow 12 due to the component force P' of the gravity P acting on the strip plate 1. .

This naturally prevents the strip plate 1 from meandering.

自然に防止している。In the present invention, the seal plate prevents the strip from meandering. For example, due to uneven thickness or curling of the strip 1, the third
An example of deviation in the direction of arrow 11 in FIG. Band plate 1
deviates in the direction of arrow 11, gap 1 between seal plate 4 and band plate 1
3 becomes smaller, and the gap 13' between the seal plate 4' and the strip plate 1 becomes larger. Gas is ejected from the floating gas ejection slit 9, and pressure is created between the strip plate 1 and the gas pad surface 2. However, since the gas is difficult to flow out from the small gap 13, the gas is ejected from the sealing plate 4 side. The pressure of the gas pad increases and lifts the strip 1 upwards. On the other hand, since gas easily flows out from the seal plate 4' side, the pressure of the gas pad is small and the strip plate 1 is not lifted upward. For this reason, the strip plate 1 is
), the strip plate 1 is inclined on the gas pad surface 2, but due to the component force P' of the gravity P acting on the strip plate 1, the strip plate 1 moves in the direction of the arrow 12. Even if the plate 1 shifts in the direction of the arrow 11 due to, for example, uneven thickness or curling, the strip l will naturally return to the direction of the arrow 12. Therefore, the seal plates 4 and 4' naturally prevent the strip 1 from meandering.

る力が弱い。FIG. 3 (C-1) is a comparative example in which seal plates 4, 4' are provided over the entire length of the arc surface. At this time, since the gap 13 is small and the strip plate 1 is inclined, the width end of the strip plate 1 comes into contact with the seal plate 4 at a point Q. This contact hinders the smooth running of the strip 1, and also causes scratches on the width edges of the strip 1. In the present invention, the seal plates 4, 4' are arranged only on the top of the gas pad surface 2, as shown in FIG. 3 (C-2). According to the knowledge of the present inventors, the elevation angle θ is 30
~70° is preferred. If it is less than 30', the force for inclining the strip plate 1 is weak.

走行が阻害され、また帯板にはすり疵が発生する。Further, even if the angle exceeds 70°, the strip plate 1 only bulges laterally, and the increase in the force for tilting it is small, and as already mentioned, since the end of the strip plate 1 contacts the seal plate 4, the strip plate 1 Smooth running is obstructed, and scratches occur on the strips.

る。In the present invention, the V-shaped slit and the seal plate can prevent the strip plate 1 from meandering even when used alone, but according to the findings of the present inventors, by using the V-shaped slit and the seal plate together, the strip plate 1 can be prevented from meandering. The effect of preventing meandering running in No. 1 increases synergistically.

, 5'. FIG. 4(A) shows a conventional comparative example in which no guide nozzle is provided, and the dotted line 6-1 is the running path of the strip plate 1 without ear waves or middle elongation (hereinafter abbreviated as ear waves, etc.). According to the observations of the present inventors, when the strip plate 1 is bent along the gas pad surface 2 above 14-14' below the floating gas jet slit 9, the height of the ear waves, etc. However, when it hangs below 14-14', the height of the ear wave etc. is large at d□. Also, since the strip 1 is not restrained below the arrow 14-14',
It runs while swinging in the direction of arrow 15. Therefore, the ear wave portion and the middle extension portion of the band plate 1 are likely to come into contact with the lower ends R and R' of the gas pad surface 2.

Since the amount of gas injected from the guide nozzles 5, 5' is adjusted by the size of ear waves etc. and the swinging path of the strip plate 1, the gas to be ejected from the guide nozzles 5, 5' is introduced from a separately provided gas introduction hole 8-2. do.

0.2kg/■”, traveling speed of the strip 5m/++in~
The speed was 60 m/win, and the strip was transported while being floated at d0 = 5 to 10 cm. There was little meandering of the strip and there was no contact between the strip and the gas pad, making stable operation possible.
