Abstract

PURPOSE:To elevate carrying stability and heating capacity of a strip, and to homogenize its heat treatment, by providing a surface holding device for partially positioning by non-contact a metallic strip running by a catenary system in a heating furnace. CONSTITUTION:A strip path 18 of a catenary curve is formed by providing chambers 14, 16 on the upper part and the lower part in a continuous heat treatment furnace 2. A running strip 4 is heated to a prescribed temperature by blowing hot blast from nozzles provided on these chambers 14, 16. On one or more suitable positions in a furnace shell 6 of the furnace 2, a strip surface holding device such as a static pressure pad 50 having a slit, etc. is provided symmetrically in the width direction of the strip 4 so as not to contact with the strip 4, and hot blast is jetted toward the inside. As a result, hydrostatic pressure is formed between the strip 4 and the static pressure pad 50, and stable supporting force is worked on the strip 4. According to this device, a distance between the strip 4 and the chambers 14, 16 can be shortened, and the heating capacity is increased.

動することとなる。Conventionally, in catenary heating furnaces in which a continuously running metal strip is heated in a suspended state, there is nothing to control the position of the strip between the upper and lower nozzles that eject hot air, so long When suspended conveyance is carried out in a nupan, the metal strip may twist or fall, and the distance between the nozzle and the metal strip will constantly change.

対する適切な矯正方法は未だ見い出されていないのであ
る。Since such a large distance is required, the catenary method has the disadvantage that the heat transfer capacity is reduced and, for example, dry baking on painted strips tends to be uneven in the oven. Moreover, an appropriate method for correcting the twisting and falling of the metal strip in the above-mentioned catenary heating furnace has not yet been found.

を目的とするものである。The present invention has been made in view of the above circumstances, and while retaining the advantages of the catenary method, it solves the problem of transport stability, which is the drawback, and has a large space between the metal strip and the nozzle. It is an object of the present invention to provide a continuous heat treatment furnace that has advantages such as being able to shorten the distance and increase heating efficiency.

持装置を設けたことにある。In order to achieve this object, the present invention provides a furnace for continuously heat-treating a predetermined metal strip while running it in a non-contact state. A strip surface holding device is provided for positioning the running position of the metal strip in a non-contact manner at at least one point of a catenary curve drawn by the strip.

た効果を奏することとなったのである。Since the catenary curve of the metal strip is partially held by the surface holding device, the catenary portion is substantially shortened, and the occurrence of twisting and falling is effectively prevented. Also, the transport stability of the metal strip in the furnace is significantly improved, and the distance between the metal strip and the nozzle can be shortened, so that the heating capacity is increased and heating, e.g. This makes it possible to homogenize the baking process, which in turn makes it possible to increase the conveyance speed and shorten the furnace length, resulting in excellent energy savings and cost reductions. .

通路１８が形□成されている。First, in FIG. 1, reference numeral 2 denotes a continuous drying/baking furnace that dries and bakes paint while running a metal strip 4. Inside the furnace shell 6, there is a drying zone 8 at the front and a heating zone at the center. A polymerization reaction (baking) zone 12 is formed at the rear of the IO1. In each band, an upper chamber 14 is provided at the -F stage, and a lower chamber 16 is provided at the lower stage, and a catenary curved strip passage 18 is formed between both chambers.

るのである。The metal strip 4 thus passes through guide rollers 22, 24 in front of the furnace shell 6 and is coated with a predetermined coating by means of coke 26 and 28 before and after the guide rollers 24. While passing through the catenary curved strip passage 18 formed in the furnace shell 6 through the furnace shell inlet 20, the strip is dried in the drying zone 8, heated and raised to the polymerization reaction temperature in the temperature increasing zone IO. The polymerization reaction zone 12 is heated and baked under pressure. Thereafter, the metal strip 4 exits the outlet 30, is cooled by forced air in the cooler 82, and is changed direction by the guide roller 34. Then, the metal strip 4 is further cooled by water jet in a water cooling chamber 36, dehydrated in a Ringerlow/L/38, dried in a drying device 40, and removed by guide rollers 42, 4.
4. It is 7x so that it is led to the next process after passing through 46.

。By the way, between the drying zone 8 and the temperature rising zone IO in the furnace shell 6 and between the temperature rising zone IO and the polymerization reaction zone 120, a predetermined static pressure area is created by blowing hot air toward the metal strip 4 from above and from the side. Static pressure (EE device)
are respectively provided in the width direction of the strip 40.

５０の面には一対のスリ・ント５２が設けられている。As shown in FIG. 2, the static pressure pad 50 is a hollow rectangular cylinder that extends continuously in the width direction of the metal strip 4, and the static pressure pad 50 faces the metal strip 4. A pair of slits 52 are provided on the surface.

そして、それぞれのス１」ット５２は、互いに対称的に
内側に向けて熱風をＩＩＱ出するようになっている。The respective slots 52 are arranged to emit hot air IIQ inwardly symmetrically with respect to each other.

しめ得ることとｌるのである。Then, due to the jet of hot air from this slit 52,
There is a static pressure area 5 between the metal strip 4 and both slits 52.
4 is formed to exert a stable supporting force on the metal strip 4, and since the acting force is inversely proportional to the square of the distance between the metal strip 4 and the static pressure band 50, the metal strip 4 This means that the supporting position of the device can be automatically stabilized.

である。In this way, the running position of the metal I-IJ knob 4 is determined in a non-contact manner at two locations on the catenary curve drawn by it within the furnace shell 6, so that the acting force of the static pressure pad 50 is The weight of the metal strip 4 is not acted upon by lifting it, but only acts to return it to its original position when the metal strip 4 is displaced from the catenary curve. The static pressure required for the fan 50 can be small, and the fan power can also be small-scale, and its control is extremely easy.

るのである。In addition, as shown in FIG. 3, if the metal nut trip 4, which is supported in a floating state by being sandwiched between the upper and lower static pressure pads 50, is twisted or fallen down, the Since the wind pressure on the static pressure pad 50 is inversely proportional to the square of the distance, the wind pressure distribution changes and the metal strip 4 is immediately automatically returned to the state shown in FIG. 4, so the metal strip 4 is always stable. This allows for smooth driving.

Therefore, since the distance between the metal strip 4 and the nozzles provided in both chambers 14 and 16 is shortened as much as possible (1'), the impingement speed of the hot air is increased.
The heating capacity is increased, thus shortening the drying time and making baking more uniform.Therefore, it is also possible to increase the conveyance speed or shorten the furnace length, resulting in energy savings/L.
It also has an excellent effect in reducing costs.

ある。In addition, although the example in which the static pressure pad 50 is placed on the upper and lower surfaces of the metal strip 4 is shown, it is only necessary that the static pressure pad 50 is placed on at least one side (the other may be a general hot air jetting nozzle). Furthermore, instead of arranging them at two locations on the catenary curve, it is also possible to arrange them at one location or at three or more locations.
