Definitions

  • the present invention relates to a heat exchange device with a flat product.
  • This device includes gas pressurization means at least one plenum chamber, the caisson comprising on a front face several blades forming a conduit for the ejection of the gas direction of a surface of the rolled product, the blades being superimposed to others according to the direction of travel of the rolled product and constituting a gas outlet opening extending across the width of the rolled product.
  • Each space separating two superimposed blades has a depth in a direction perpendicular to the surface of the rolled product and a width in the longitudinal direction of the rolled product sufficient to allow gas evacuation without disturbing the gas outlet of the adjacent blades.
  • the space provided between the blades facilitates the evacuation of gas at level of the surface of the rolled product and does not interfere with the emission of gas in outlet of the blade opening.
  • the present invention aims to improve such a device for exchanging heat, and in particular to facilitate the evacuation of gas from the device after its impact on a flat product.
  • the invention thus relates to a heat exchange device with a flat product as defined in claim 1.
  • the evacuation of gases after impact on the surface of the flat product can be made on both sides of the box, opposite the blades forming gas pipe on the front of the box.
  • the outgoing gas flow is therefore directed towards the rear of the flat product, without interfering with the emission of gas through the orifices of the blades. All risk of gas stagnation on the surface of the treated product is thus carefully avoided, as well as any gas flow parallel to the surface to treat both in the width direction and in that of the scrolling of the product.
  • each blade flares towards the flat product of so that the gas, after impact on the flat product, can return to the back of the device, on each side of the box.
  • the device heat exchange comprises gas outlet openings after ejection, located in a plane defined by a rear face opposite to said front face of the caisson.
  • the evacuation from the back of the box avoids any movement of gas along the surface of the flat product as happens in conventional devices in which the boxes are continuous or arranged side by side and prevent the return of the cooling gases to the rear.
  • the gas can be evacuated from the device heat exchange according to the invention without generating cooling preferential from the edges of the flat product.
  • the device heat exchanger comprises at least two boxes arranged in the width of the flat product, the spacing between said boxes being such that the gas is evacuated between said boxes at a lower speed or equal to 20 m / s.
  • the ratio of half the gas flow rate in m 3 / s at the outlet of two adjacent strips along the width of the product over the section in m 2 of the space separating said boxes comprising said blades is less than 20, said section extending in a plane parallel to the flat product and to the running direction of the flat product.
  • the ratio of the speed of the gas in a box over the speed of the gas leaving the blades integral with said box is less than 0.2.
  • the box forms a gas tank under pressure almost without circulation, ensuring a uniform speed for ejection of gases.
  • the means gas pressurization systems have several fans adapted to supply gas to one or more boxes.
  • each box can thus be regulated independently or by sub-group of boxes, allowing to adjust, in the width of the flat product, the cooling rate depending on the profile desired thermal.
  • the invention may also apply to a device for heating a flat product.
  • an installation of continuous cooling of a flat product such as a rolled product 1 can include several cooling devices 10, here four in number, distributed over the path of the rolled product moving between rolls of transport 2.
  • the laminated product scrolls vertically between the cooling devices 10 generally arranged two by two, on each side of the rolled product in order to simultaneously cool the product by its two faces.
  • the transport rollers 2 stabilize the rolled product 1. They can cause a slight deflection to the rolled product 1, lower or equal to 15 ° in order to limit the vibration of the rolled product 1.
  • Such a cooling installation can be used by example in a continuous annealing line for strip processing steel, in which the rolled product passes by vertical passes in different treatment chambers.
  • These steel strips have a thickness of between 0.15 and 2.3 mm and their width can reach up to 2 m.
  • the cooling device 10 includes boxes 11 which are adapted to contain a pressurized gas.
  • Each box 11 comprises several blades 12 which form conduits for the ejection of gas towards the rolled product 1 to be cooled.
  • blades 12 are superimposed on each other as illustrated in FIG. 1, in the direction of travel of the rolled product 1, so as to cool the surface of the product as it travels through the exchange device heat 10.
  • the height of the stack of blades 12 over the height of a box It is preferably less than or equal to 6 m.
  • These blades 12 have at least one outlet 13 as shown in Figure 2, which extends across the width of the rolled product 1. This outlet orifice 13 thus opens at the end of the conduit formed by the blade 12 which extends from the box 11 in the direction of the rolled product 1.
  • the cross section of the blades 12, in a plane perpendicular to the rolled product 1, decreases from the box 11.
  • the outlet orifices 13 may be circular holes, rectangular, oblong, etc., or small slits made at the end of each blade 12.
  • the blade 12 could also have only one orifice for outlet 13 forming a slit opposite the rolled product 1.
  • Each space separating two superimposed strips 12 has a depth in a direction perpendicular to the product laminate 1 and a width in the longitudinal direction of the laminate product 1 sufficient to prevent the accumulation of cooling gas near the surface of the rolled product 1.
  • the depth of the separation spaces of the blades 12 is greater than 200 mm, and preferably greater than 300 mm.
  • the number of blades 12 of the device 10 and the number of openings 13 are such that the total section formed by the openings 13 is between 1% and 5% of the surface covered by all of the blades 12, and preferably between 2 and 4% of this area.
  • the blades 12 of a box 11 are dimensioned such that so that the evacuation of the gas in the section S between these blades 12 is carried out at a speed less than or equal to 20 m / s at any point.
  • the section corresponds to the section of space taken in the plane of Figure 2, perpendicular to the rolled product 1 and parallel to the direction of scrolling of the rolled product 1.
  • the depth P can be constant in the width of the blade 12, or variable, as illustrated in FIGS. 3A and 3B, if we want to give the gas flow back a speed more directed towards the rear of the device.
  • a partition 12a thus extends between the superimposed blades 12, at from the casing 11, so that the depth P at the center of the blade 12 is weaker than at its ends.
  • depth is a continuous function P (x) which varies along the distance x from the axis of symmetry of the blade 12 (in the case of FIG. 3A where a symmetrical return of the gas is produced by the two sides) or from one end of the blade 12 (in the case of FIG. 3B where gas return is only carried out on one side of the blade).
  • the flow between two blades 12 at a distance x from the axis of symmetry is equal to qx / l where q is the flow per blade (m3 / s) and I the width of the end of the blade 12 parallel to the width of the product with x ⁇ I / 2.
  • the cross-section for the return gas at the same distance x is equal to wP (x).
  • Limiting the return speed to 20 m / s therefore implies that, for any value of x between 0 and I / 2, we have: P (x) ⁇ qx / 20.Iw, x, I and w being expressed in meters.
  • the condition is also: P (x) ⁇ qx / 20.Iw, x varying this time between 0 and I.
  • the cooling device comprises at least one box 11, here in number of five. These boxes 11 are distributed across the width of the rolled product 1 and extend in the longitudinal direction of the moving laminated product, parallel to each other.
  • each box 11 and the distance between the boxes 11 allow the evacuation of gas between boxes 11 without disturb the gas outlet of the blades 12.
  • This distance denoted D 1-2 or D 2-3 in FIG. 4, may have a different value from one pair of boxes 11 to another pair.
  • the boxes 11 have a cross section which is substantially parallelepiped, the distance between the boxes 11 corresponding to the distance separating their flanks placed opposite.
  • Gas outlet openings 14 after ejection are thus located between the boxes 11, in a plane defined by the rear faces opposite to the front panels 11.
  • the gas can thus be recovered on a rear face of the device heat exchange 10, opposite the rolled product 1, which avoids gas circulation along the surface of the rolled product 1 and a greater cooling of the edges of the rolled product 1 than at its center.
  • the ratio of half the gas flow rate in m 3 / s at the outlet of two adjacent strips 12 along the width of the product over the section in m 2 of the space separating the boxes 11 comprising these strips 12 is less than 20.
  • This section taken in the plane of Figure 3, extends in a plane parallel to the rolled product 1 and to the direction of travel of the rolled product 1.
  • the device comprises, as here, several boxes 11 arranged parallel in the width of the rolled product 1, the section of the space separating the boxes 11 is equal to the sum of the sections of the spaces separating the boxes 11 two by two.
  • this section would be equal to the sum of the sections, taken from left to right in FIG. 4, L x (D 3-4 + D 2-3 + D 1-2 + D 1 -2 + D 2-3 + D 3-4 ).
  • the distance L is less than or equal to 300 mm, and preferably less than or equal to 150 mm.
  • each box 11 is further distributed regularly on a front face of the box 11 in the direction of scrolling of the laminated product, each blade 12 of a first box 11 being adjacent to a blade 12 of a second box 11 in the plane defined by the gas outlet ports 13 (see in particular Figure 6).
  • the blades 12 have a profile substantially divergent in the transverse plane of the rolled product so as to constitute at their ends, all adjacent in this transverse plane, a uniform gas outlet orifice 13 over the entire width of the rolled product 1.
  • This port 13 may be formed of a single slot or a series of small ports evenly distributed over the entire width of the device.
  • the width of the gas outlet 13 in the width of the product laminated is thus greater than the width of the box 11.
  • the ratio of the speed of the gas in a box 11 on the speed of the gas leaving the blades 12 secured to the box 11 remains less than 0.2.
  • the speed of the gas in each box 11 can be of the order 10 m / s while the speed at the output of the blades 12 can reach and exceed 150 m / s.
  • the boxes 11 thus form reservoirs of pressurized gas practically without circulation, which allows a regular flow gas leaving the blades 12.
  • Each box 11 has a gas supply opening 15 under pressure which can be connected to pressurizing means gas such as a fan 16 (see Figure 1) or a compressor.
  • pressurizing means gas such as a fan 16 (see Figure 1) or a compressor.

  • the gas outlet 18 is preferably located in the center of the rear wall 17a of the enclosure 17, halfway up the cooling 10 and has substantially the same width as this (fig. 5).
