現象を生じて好ましくない。 Conventionally, a method for floating and supporting band-shaped materials such as metal strips in a non-contact manner was developed using the
There is one described in Publication No. 11451. In this method, a number of nozzles each having a slit-shaped gas outlet facing inward are placed opposite each other in the width direction of the belt-shaped material conveyance path, and gas is ejected from the outlet. This method uses static pressure from gas to levitate the strip-shaped material. When a strip material is transported and heat-treated using buoyant support, the strip material will not deform at all if it is relatively thick. Deforms due to pressure etc.
This is undesirable because it causes so-called canoeing or seagull wing phenomenon.
これを防止するには、ノズルボツクスへの気体
供給圧力を変えればよいが、厚い金属ストリツプ
と薄い金属ストリツプとを交互に、かつ連続して
搬送処理する場合、圧力調整が面倒である。 This can be prevented by changing the gas supply pressure to the nozzle box, but when thick metal strips and thin metal strips are conveyed alternately and continuously, adjusting the pressure is troublesome.
また、前記方式は、その噴出気体がジエツト流
で高い熱伝達率を有しているため、供給気体を高
温気体あるいは低温気体として、金属ストリツプ
の加熱・冷却を行なわせるのが一般的である。 Furthermore, in the above method, since the ejected gas is a jet flow and has a high heat transfer coefficient, it is common to use a high temperature gas or a low temperature gas as the supplied gas to heat and cool the metal strip.
それ故に、前述のように、搬送材料により供給
気体圧を変化させると、低供給気体圧時には十分
な熱伝達を得ることができなくなると云う欠点を
有する。 Therefore, as mentioned above, changing the supply gas pressure depending on the carrier material has the disadvantage that sufficient heat transfer cannot be obtained at low supply gas pressures.
本発明は、前記の欠点を除去するためになされ

とする帯状材料の浮揚支持装置を提供しようとす
るものである。 The present invention was made in order to eliminate the above-mentioned drawbacks, and the present invention maintains the jetting pressure of one of the gas jetting ports of the nozzle as it is to ensure sufficient heat transfer in accordance with the belt-shaped material to be conveyed. It is an object of the present invention to provide a flotation support device for a band-shaped material that can control the amount of ejection of the other side to increase or decrease the static pressure, thereby levitating and supporting any band-shaped material without deforming it.
つぎに、本発明を一実施例である図面にしたが
つて説明する。 Next, the present invention will be explained with reference to the drawings which are one embodiment.

ないノズルヘツダから供給された圧力気体を前記
噴出口3a,3bから噴出し、金属ストリツプ1
をその静圧力により浮揚支持するものである。 In FIG. 1, reference numeral 1 indicates a metal strip that is a belt-shaped material to be conveyed, and reference numeral 2 indicates nozzles arranged vertically in the width direction of the metal strip 1 (the upper nozzle is omitted). It has spout ports 3a and 3b formed of a pair of slits facing inward on both sides, and pressurized gas supplied to the nozzle box 4 from a nozzle header (not shown) is spouted from the spout ports 3a and 3b, and the metal strip 1
It is supported by floating by its static pressure.
本発明においては、前記ノズル2の一方の噴出

る。 In the present invention, a spout closing member 5 is provided near one spout of the nozzle 2, for example, the spout 3b.
It has been established. This closing member 5 consists of a plate-shaped part 7 having a protruding piece 6 perpendicular to the metal strip 1 at one end, and this plate-shaped part 7 is rotatably attached to the nozzle 2 by a hinge 8. .

プ1を浮揚支持する。一方、金属ストリツプ1が
薄い場合には、閉塞部材5を実線で示すように反
時計回り方向に回動して噴出口3bを閉塞する。 When the metal strip 1 is thick, the jet nozzle 3b is opened and the metal strip 1 is suspended and supported by the static pressure caused by the gas jetted from both the jet nozzles 3a and 3b, as in the conventional case. On the other hand, if the metal strip 1 is thin, the closing member 5 is rotated counterclockwise as shown by the solid line to close the spout 3b.

出気体圧は厚い金属ストリツプ1の場合と同一で
あるため、何ら熱伝達が悪くなることもない。 In this case, a part of the gas ejected from one of the ejection ports 3a flows as shown by a in the conventional manner, but the flow of the remaining gas is changed by the protruding piece 6 and comes into contact with the metal strip 1 at a gentle angle. Form a streamline b. That is, since the amount of ejected gas is small and the ejected gas hits the metal strip 1 at a gentle angle due to the streamline b, the metal strip 1 is not deformed at all. Furthermore, since the pressure of the gas ejected from the ejection port 3a is the same as in the case of the thick metal strip 1, heat transfer does not deteriorate in any way.

変化させないため熱伝達も十分に得ることができ
る。 As is clear from the above description, according to the present invention, the amount of gas ejected from one gas ejection port of the nozzle is controlled by the closing member in accordance with the band-shaped material.
Since the static pressure generated between the nozzle and the strip-shaped material is increased or decreased, the thin strip-shaped material can be supported in suspension without being deformed even if the gas supply pressure remains unchanged. Moreover, sufficient heat transfer can be achieved because the pressure of the gas ejected from the ejection port is not changed.

送熱処理を施すことができる。 That is, with a simple structure, sufficient heat transfer can be ensured from a thin strip material to a thick strip material, and the levitation transport heat treatment can be performed.
