Definitions
- the present invention relates to a method and a device for suppress vibrations of continuously moving belts in areas a heat treatment or coating line where the blowing a gas on a continuously moving strip.
- the invention applies in particular, without however being limited to this application to jet blast cooling devices fitted to lines heat treatment or continuous coating of metal strips.
- FIG. 1 of the drawings represents in perspective and schematically, an area of rapid cooling 2 by blowing gas by jets, according to the previous state of the technique, which is crossed by a metal strip 1 passing over rollers 3 and 12.
- the strip 1 is exposed to the cooling gas jets blown through a plurality of pairs of boxes such as 4 and 5, each box being positioned on either side of the strip 1.
- the cooling boxes 4 and 5 have a limited length in order to allow the implantation of one or more a pair of stabilizing rollers such as 9 and 10, placed between two consecutive boxes as clearly seen in Figure 1 and which are intended to guide and stabilize the strip and in particular to limit vibrations of the latter under the action of the cooling jets.
- blowing boxes 4 and 5 can be divided transversely into several boxes such as 6, 7 and 8 provided with gas supply means independent 13, 14, 15 and whose flow supply characteristics and / or pressure can be adjusted according to the level of cooling to be obtained on the strip.
- FIGS. 2 and 3 There are various embodiments of the means for blowing the gas cooling on the strip.
- US-B-3,068,586 describes a number examples of embodiment of these blowing means.
- Figure 2 of the drawings attached represents in perspective and schematically a box of cooling of known type 4, provided with blowing holes 16, the diameter and mesh are adapted to the desired level of cooling.
- the Figure 3 is a representation similar to Figure 2 but in which the cooling box 4 of known type is provided with blowing nozzles cylindrical 17 which are arranged in a rectangular mesh or in diamond over the entire surface of the box 4.
- Figure 4 shows in a similar view to FIGS. 2 and 3 a known variant of a blowing box 4 which is provided with blowing nozzles in the form of slots 18 arranged on the entire width of the box.
- the cooling gas which is blown onto the strip through the holes 16, the nozzles 17 or the nozzles 18 is channeled transversely over the entire width of the box, between it and the strip, so that it can be recycled by ducts which are located outside the cooling zone 2.
- the means ensuring these functions are well known to those skilled in the art and they have not not shown in Figure 1.
- FIG. 6 of the accompanying drawings there is shown a strip having a heterogeneous distribution of tension over its greater width in the center of the strip only on the banks, the origin of which may be rolling, the profile of rollers or heterogeneous heating or cooling or any other.
- the belt tension is concentrated in its central part, the edges of the longer strip are less taut.
- This difference of "soft" edge tension can cause the distance between the edges of the strip 1 and the boxes 4 and 5, along b and c, which causes the variation of the flow rates V's1, V's2, V'i1 and V'i2.
- V'n1 is more small than V'n2 and V's1 is larger than V's2.
- the band moves to a maximum position for which the pressure on side b increases and the pressure on side c decreases, and the opposite movement begins.
- This phenomenon creates the torsional vibration of the band, symmetrical or not, which can be represented according to figure 7 which illustrates this vibration between two consecutive rolls.
- This vibration in high flow blowing areas can reach amplitude values such that they can cause a contact between holes 16, nozzles 17 or 18 and the strip, which drives well understood, the appearance of surface defects on the strip 1 thus degrading the product obtained.
- the vibrations of the strip may be such that they cause degradation of the cooling boxes and their holes or blowing nozzles.
- the solution generally adopted in the prior art, for removing or at least reducing the vibration of the tape is to increase the distance between holes 16 or nozzles 17 or 18 and strip 1 or limit the blowing pressure in the boxes, which leads to limitation of the cooling efficiency resulting in a reduction of the production of the line in a proportion which can reach 40% of the nominal production.
- the rolling defects of the strips to be treated in particular the long edges increase the risk of vibration of an exposed strip to a regime for recycling the gases blown on the unstable strip.
- the evolution of the steel grades currently treated imposes slopes of cooling faster and faster from temperatures increasingly higher, with low band voltages, which generalizes the appearance of the torsional vibration of the strip.
- the present invention has therefore set itself the objective of solving the problem described above, that is to say to suppress the vibrations of the band in the cooling zones, improving the recovery of cooling gases between the strip and the blowing box and by imposing a fixed position on the bandaged.
- this invention aims firstly at a method making it possible to suppress vibrations of continuously moving belts in areas a heat treatment or coating line where the blowing a gas onto a continuously moving strip, in particular in jet blast cooling devices fitted to lines heat treatment or continuous coating of metal strips characterized in that it consists in adjusting the pressure and / or the flow rate of the gas cooling below the nominal value in an area located on a bank of the strip, on one side of it and at a higher value lower than the nominal value, on the opposite bank, located on the other side of the bandaged.
- the invention also relates to a device intended to suppress vibrations from continuously moving belts in the cooling zones by gas blowing by jets equipping heat treatment lines in continuous metal strips, this device implementing the method as as defined above and being characterized in that it comprises boxes of blowing comprising means making it possible to adjust the pressure and / or the flow rate cooling gas at a lower value than the nominal value in an area located on one bank of the strip in the box located on one face of the strip and at a lower value than the nominal value on the opposite bank, on the box located on the other side of the strip.
- Figure 8 very clearly represents schematic in section through a horizontal plane two blowing boxes 8 and 21 arranged on either side of the strip 1 in continuous movement.
- each box is divided into several boxes elementary.
- the box 8 is divided into three boxes 8, 7 and 6 each supplied individually with blowing gas at 13, 15 and 14.
- each of the power supplies of the boxes is provided means for adjusting the flow rate and / or the supply pressure of the box corresponding.
- These means are implemented and implemented so as to obtain a right / left asymmetrical blowing of the strip 1, as shown in FIG. 8, which creates a privileged direction of the flows of gas recovery on a band maintained in an equilibrium position.
- these means make it possible to obtain a lower pressure level. in the end box 6 on one side of the strip and on the box opposite end 21 on the other side of the strip.
- figure 8 we have represented by arrows the resulting pressure level, in the different parts of the boxes on each side of the strip.
- box 8 was divided into three boxes 8, 7 and 6 each supplied individually with blowing gas at 13, 15 and 14 respectively.
- these supply means are equipped with means for adjusting the pressure and / or the flow rate of cooling so as to obtain the right / left asymmetry of the strip specified above.
- the adjustment of the pressure of the cooling gas is obtained by creating, in a box unique pressure drop to limit the pressure of the gas jets in previously defined areas to obtain asymmetry wanted.
- This pressure drop can be fixed or variable, with in particular a possibility to modify the value of the pressure drop in function of the vibration to be fought.
- an opening can also be provided. different from the blowing boxes between the right and left side of the strip, which favors a direction of gas recovery towards the side of the sections of most important recoveries.
- suction means are provided external to the cooling zone, designed to draw in exhaust gases differential between the right and left sides of the strip, creating a preferred direction of gas flow.
- the asymmetry sought is obtained by a variation in the length of the nozzles of blowing, when these are of the tubular type, between the right side and the side left of the boxes.
- means can be provided for twisting the strip between the roller 3 located at the top of the cooling zone 2 and the stabilizer rollers such as 9 and 10 in Figure 1, the length of a blowing box, in order to immobilize the strip in an extreme position of its vibration range.
- These means can also be provided between two groups of stabilizing rollers.
- the measurement of the vibration of the strip (amplitude and position of the latter) can be performed using appropriate sensors whose information is analyzed by video images to ensure regulation of operations performed in order to limit the vibration of the belt for example pressure regulation in the blowing boxes or of the position of said boxes.
- FIG. 9 of the accompanying drawings illustrate a another example of embodiment of a blowing box 4 provided with nozzles blowing 18 in the form of slots and designed to suppress the effect of the lateral discharge of the blowing gases after they have struck the strip.
- the nozzles 18 are independent, they are generally supplied with cooling gas at their ends and they are separated from each other so as to provide an area of gas recovery 27 between two contiguous nozzles. Thanks to this arrangement, obtains a rear recovery of the gases blown on the strip, this recovery taking place in this space 27, perpendicular to the strip, without the velocity vector of this recovery does not have components parallel to the strip, the transverse component of the gas recovery speed of blowing being thus suppressed.
- the invention provides means to limit the instability of trade flows cooling gases circulating towards the edges of the strip and which cause the previously observed torsional vibration of the strip. It is therefore possible, thanks to the invention, to work with tape tensions low and high flow rates and / or pressures of the cooling gas thus allowing rapid cooling cycles to be obtained.
- the invention makes it possible to eliminate the production limitations imposed by the absence of a control of the vibration of the equipment strip according to the prior art. It also allows the deletion of surface defects found in equipment according to the technique anterior, during contact between the strip and the cooling boxes.
- this invention is not limited to the modes of implementation described and / or mentioned above but that it includes all variants. Furthermore, and as mentioned in the preamble to this description, this invention is not limited to cooling devices but it can be applied in all areas of a heat treatment or coating line where performs the blowing of a gas on a continuously moving strip.
