Definitions

  • the invention relates to the field of rolling plates or trays made of aluminum alloys.
  • the invention relates to a particularly rapid, homogeneous and reproducible cooling process for the plate between the homogenization and hot rolling operations.
  • DE 198 23 790 A1 discloses a method according to the preamble of claim 1.
  • the invention also relates to the installation or equipment allowing the implementation of said method.
  • the transformation of the aluminum alloy rolling plates resulting from the casting requires, before hot rolling, a metallurgical homogenization heat treatment.
  • This heat treatment is carried out at a temperature close to the solvus of the alloy, higher than the hot rolling temperature.
  • the difference between the homogenization temperature and the hot rolling temperature is between 30 and 150 ° C, depending on the alloys.
  • the plate must therefore be cooled between its exit from the homogenization furnace and its hot rolling. For reasons either of productivity or of metallurgical structure, in particular to avoid certain surface defects on the finished sheet, it is very desirable to be able to cool the plate quickly between its exit from the homogenization furnace and the hot rolling mill. .
  • This desired plate cooling rate is between 150 and 500 ° C / h.
  • the air cooling is particularly slow: the air cooling speed of a 600 mm plate thickness is included between 40 ° C / h in still air or under natural convection, and 100 ° C / h in ventilated air or forced convection.
  • Cooling by means of a liquid or a mist is much faster because the value of the exchange coefficient, known to those skilled in the art under the name HTC (Heat Transfer Coefficient), between a liquid or a mist and the hot surface of the metal plate is clearly greater than the value of this same coefficient between the air and the plate.
  • HTC Heat Transfer Coefficient
  • the liquid chosen alone or in the mist is for example water and, in this case, ideally deionized water.
  • the HTC coefficient is between 2000 and 20,000 W / (m 2 .K) between water and the hot plate while it is between 10 and 30 W / (m 2 .K) between air and hot platter.
  • Thermal heterogeneity is a major handicap in cooling using a liquid or a mist. It poses a problem not only for the following process, that is to say the hot rolling, but it is also potentially harmful for the final quality of the product, namely the aluminum alloy sold in the form of coils or high sheets. mechanical characteristics.
  • the subject of the invention is a process for cooling a rolling plate made of aluminum alloy with typical dimensions of 250 to 800 mm in thickness, 1000 to 2000 mm in width and 2000 to 8000 mm in length according to claim 1.
  • thermal difference is understood to mean the maximum difference between temperatures recorded over the entire volume of the plate, or else DTmax.
  • the cooling is carried out in at least two phases: A first spraying phase during which the plate is cooled in an enclosure comprising ramps of nozzles or nozzles for spraying liquid or cooling mist under pressure, distributed in the upper and lower parts of said cell, so as to spray the two large faces, upper and lower of said plate,
  • this time is about 30 min for a total cooling of the order of 150 ° C from substantially 500 ° C, and a few minutes for a cooling of the order of 30 ° C.
  • the spraying and thermal uniformization phases are repeated, in the case of very thick plates and for an overall average cooling greater than 80 ° C.
  • the coolant including in a mist, is water, and preferably deionized water.
  • the head and the foot of the plate that is typically the 300 to 600 mm at the ends, are less cooled than the rest of the plate, so as to maintain a hot head and foot, a configuration favorable to the plate engagement during reversible hot rolling.
  • the cooling of the head and of the foot can be modulated either by starting or switching off the nozzle ramps or spray nozzles, or by the presence of screens preventing or reducing the spraying by said nozzles or nozzles.
  • the phases of spraying, and no thermal uniformization can be repeated, and the head and the foot of the plate, typically 300 to 600 mm at the ends, cooled differently than the rest of the plate at least in one spray cells.
  • the first spraying pass is carried out with a zero heel, that is to say a continuous watering of the plate as in figure 14 , followed, without a first phase of thermal uniformization, by a second spraying pass with a heel of a couple of ramps as in figure 12 , thus making it possible to significantly reduce the duration of the final uniformization phase necessary for the thermal balancing of the plate.
  • the longitudinal thermal uniformity of the plate is improved by a relative movement of the plate with respect to the sprinkling system: scrolling or back and forth of the plate facing a fixed sprinkling system or vice versa, displacement of the nozzles or nozzles relative to the plate.
  • the plate scrolls horizontally in the spray cell and its scroll speed is greater than or equal to 20 mm / s, ie 1.2 m / min.
  • the transverse thermal uniformity of the plate is ensured by modulating the sprinkling across the width of the plate by switching on / off nozzles or nozzles, or screening said sprinkling.
  • the subject of the invention is also an installation for carrying out the method as above, comprising a spray cell provided with ramps of nozzles or spray nozzles for liquid or pressurized cooling mist arranged in upper parts and bottom of said cell, so as to spray the two large faces, upper and lower of said plate,
  • a uniformization tunnel with calm air coming out of the spray cell in a tunnel with interior walls and the roof in an internally reflective material, allowing thermal uniformization of the plate by diffusion of heat in said plate, the heart by warming the surfaces.
  • the pairs of upper and lower nozzle ramps are placed substantially facing each other, so that the upper and lower spray lengths are substantially equal and facing each other.
  • the spraying length is controlled so as to promote the lateral evacuation of the liquid or mist sprayed on the upper face, by guiding it towards the banks of the plate where it is evacuated in the form of a cascade without touching the small faces of the plate thus allowing a very homogeneous cooling in temperature in the longitudinal and transverse directions of the plate.
  • the liquid alone or contained in the cooling mist it can be recovered, typically in a container located under the installation, recycled and thermally controlled.
  • the entire installation, spray cell and uniformization tunnel is controlled by a thermal model coded on a PLC, the thermal model determining the settings of the installation as a function of the temperature estimated by thermal measurement at the start of the spray cell and depending on the target outlet temperature, in general the temperature at the start of hot rolling.
  • the Figure 19 illustrates the thermal field of a 600 mm thick AA6016 type alloy plate cooled by about 50 ° C in one pass in the sprinkler machine set with a sprinkler head of a single boom at the ends of the table, in accordance with figure 13 . This adjustment results in a very uniform thermal field with slightly hotter ends, which is favorable for rolling.
  • the invention essentially consists of a cooling process using a cooling liquid or mist for a plate or a rolling plate of aluminum alloy, from 30 to 150 ° C in a few minutes, that is to say at an average cooling rate of between 150 and 500 ° C / hour.
  • the plate is cooled in an enclosure comprising nozzles or nozzles for spraying liquid or mist cooling under pressure, typically water and preferably deionized.
  • the nozzles or nozzles are distributed in the upper and lower parts of said cell, so as to spray the two large faces, upper and lower, of the plate.
  • the option of a step-by-step process makes it possible to limit the risks of hot spots linked to the contacts between the plate and its support, generally made up of cylindrical or conical rollers.
  • the average cooling of the tray ( ⁇ Tmoy tray) is controlled by the sprinkling time seen by each section of the tray.
  • the plate is thermally very heterogeneous in its thickness, due to a high Biot number value.
  • the spraying phase is therefore designed to limit thermal heterogeneities in the three directions of the plate.
  • the invention makes it possible in particular to control the thermal profiles in the transverse direction and in the long direction of the plate, which is very appreciable since possible thermal gradients along these two large dimensions would be difficult to absorb in a short time.
  • the thermal uniformization phase of the plate follows: After sprinkling, the plate is kept for a few minutes in a configuration of low heat exchange with its environment. These thermal conditions allow the thermal uniformization of the tray, in a few minutes for cooling of less than 30 ° C and in approximately 30 minutes maximum for cooling of 150 ° C. This phase is essential to achieve the required thermal uniformity specifications. It makes it possible to achieve a thermal difference DTmax of less than 40 ° C on a large plate.
  • the invention can also be adapted to high absolute values of cooling.
  • the average cooling of the desired plate is typically greater than 80 ° C, it is possible to cycle several times all of the “spraying” and “uniformization” phases, reducing at each “spraying-uniformization” cycle the average temperature of a very thick tray.
  • the method thus described ensures rapid and controlled cooling of a thick plate, in particular a rolling plate, made of aluminum alloy. It is also robust and avoids the known risks of local over-cooling.
  • the machine, or cooling installation itself consists of at least one spray cell, typically horizontal to the parade, on the one hand and, on the other hand, of at least one thermal uniformization tunnel.
  • the spray cell allows the implementation of phase 1 of the process described above.
  • the spray cell is made up of ramps fitted with nozzles or nozzles for pressurized distribution of the liquid or cooling mist.
  • the spraying machine can advantageously, for reasons of economy in particular, operate in a closed cycle, for example with a collecting basin placed under the spraying machine.
  • the travel speed of the plate is greater than or equal to 20 mm / s, ie 1.2 m / min.
  • the tray On leaving the spray cell, the tray is transferred, for example using automatic trolleys, into one or more uniformization tunnel (s).
  • the objective of the tunnel is to reduce as much as possible the heat transfers between the plate and the air, which is favorable to a better thermal uniformization of the plate. This thermal uniformization takes place by diffusion of heat in the plate, the core heating the surfaces of the plate.
  • the standardization tunnel consists of vertical walls and a roof in an ideally reflective material on the inside of the tunnel.
  • the machine or cooling installation made up of the spray cell and the standardization tunnel is controlled by a thermal model coded on the machine's PLC.
  • the thermal model determines the machine settings as a function of the temperature at the start of the spray cell, or inlet temperature, and as a function of the target outlet temperature, in general the rolling temperature.
  • Example 1 Uniform cooling of 40 ° C of an alloy plate of the AA3104 type.
  • the figure 5 illustrates the cooling of 40 ° C of an alloy plate of the AA3104 type according to the designations defined by the “Aluminum Association” in the “Registration Record Series” that it publishes regularly.
  • the thickness of the top is 600 mm, its width is 1850 mm and its length is 4100 mm.
  • the tray comes out of the homogenization oven at 600 ° C.
  • the plate cooling process is the one-pass process, described in figure 1 .
  • the surface spraying flow rate is 500 1 / (min.m 2 ) on the two large sides of the plate.
  • the spray heel is set to ramp torque, as described in figure 12 .
  • the tray is dry and transferred in 30 s to a uniformization tunnel for a period determined by the thermal model encoded in the automaton, here 300 s, ie 5 minutes.
  • the plate is transferred to the hot rolling mill, with a thermal uniformity better than 40 ° C on the complete plate.
  • the surface temperature of the tray drops to around 320 ° C, while the core of the tray remains almost isothermal during the spraying phase. Then, by diffusion of heat between the heart and the surface, the heart gives up heat to the surface, the plate becomes thermally uniform.
  • the thermal difference in the plate (DTmax) is maximum at the end of the spraying phase, its value is approximately 280 ° C for this configuration. It is rapidly reduced as soon as the spraying of the tray ceases: in 6 minutes of waiting (transfer then standardization in the tunnel), the thermal difference DTmax is reduced to less than 40 ° C.
  • Example 2 Uniform cooling of 135 ° C of an alloy plate of the AA6016 type.
  • the figure 6 illustrates the 135 ° C cooling of an AA6016 type alloy pan.
  • the thickness of the top is 600 mm, its width is 1850 mm and its length is 4100 mm.
  • the tray comes out of the homogenization oven at 530 ° C.

  • the surface spraying flow rate is 800 1 / (min.m 2 ) on the two large sides of the plate.
  • the watering heel is set to a ramp, as described in figure 13 .
  • the tray is transferred in 60 s to the second sprinkler cell without passing, in this example, through the optional intermediate standardization tunnel.
  • the plate then undergoes a second watering, identical to the first: each point of the plate excluding the ends is subjected to watering for 51 seconds, at a surface flow rate of 800 1 / (min.m 2 ).
  • the tray On leaving the second spray cell, the tray is transferred to the uniformization tunnel in 30 seconds. The plateau waits several minutes in the standardization tunnel. At the end, the plate is transferred to the hot rolling mill, with a thermal uniformity better than 40 ° C on the complete plate.
  • the surface temperature of the tray drops to about 60 ° C.
  • the heart of the tray remains almost isothermal during the first spraying phase and then cools down during the second spraying phase. Then, by diffusion of heat between the heart and the surface, the heart gives up heat to the surface, the plate becomes thermally uniform.
  • the thermal difference in the plate (DTmax) is maximum at the end of each of the spraying phases, its value is approximately 470 ° C for this configuration. It is rapidly reduced as soon as the spraying of the tray ceases: the thermal difference DTmax of the tray is 55 ° C after 13 minutes of waiting in the tunnel and becomes less than 40 ° C after 23 minutes spent in the tunnel.
  • Example 3 Uniform cooling of 125 ° C of an alloy plate of the AA6016 type.

  • the tray then undergoes a second watering, different from the first.
  • the plate, but this time outside the ends undergoes a second watering of 51 seconds, at a surface flow rate of 500 1 / (min.m 2 ).
  • the sprinkler stub is a couple of ramps, as described figure 12 . This adjustment tends to straighten the cold-ended thermal profile, thereby generating an almost flat longitudinal thermal profile exiting the second spray cell.
  • the tray is transferred to the standardization tunnel in 30 seconds. The plateau waits only 10 minutes in the standardization tunnel.
  • the plate is transferred to the hot rolling mill, with a thermal uniformity better than 40 ° C on the complete plate.
  • Example 3 shows that the judicious choice of the watering heels makes it possible to significantly reduce the duration of uniformization after sprinkling.
