Furthermore, the invention is directed to a method for hot rolling an aluminum hot strip of an AlMgSi alloy of the AA6xxx group in an aluminum hot strip rolling mill and a method for hot rolling an aluminum hot strip from an AlMg alloy of the AA5xxx group in an aluminum hot strip mill. hot strip rolling mill. Finally, the invention is directed to the use of an aluminum hot strip produced by one of the methods.
  • the tandem rolling mills used today for the hot rolling of aluminum alloys are universal rolling mills, on which all rollable qualities of aluminum alloys of the groups AA1xxx, AA2xxx, AA3xxx, AA5xxx, AA6xxx, AA7xxx, and AA8xxx (aluminum alloys according to DIN EN 573-3 and DIN EN 573-4) can be rolled and produced with the desired final dimensions.
  • These aluminum tandem hot rolling mills are made compact with a stand spacing between 4 m and 6 m. With larger scaffolding distances, there is a growing danger that the strip will no longer run centrically into the scaffold due to lateral bleeding.
  • An aluminum hot strip rolling mill is also off the DE 20 2011 050 449 U1 known.
  • This document discloses an aluminum hot strip rolling mill with a two-part tandem finishing train, wherein a cooling section is formed between the two parts of the tandem finishing train.
  • This cooling section is more effective than a cooling section arranged in the inlet region of a tandem finishing train, since after passing through part of the tandem stands, the aluminum hot strip thickness is lower and, if necessary, a lower hot strip temperature has been established on reaching this cooling section compared to the inlet temperature.
  • a generic aluminum hot strip rolling mill is from the DE10349950 A1 known.

  • the invention is therefore based on the object to provide a solution that makes it possible to set cooling curves and temperature-time paths in the aluminum hot strip rolling in a tandem finishing mill in the rolling stock in an improved manner. Also, a solution should continue to be created, which makes it possible to avoid the hitherto necessary rest periods of the material prior to further processing or further processing or to reduce the production time and thus increase the output while compact design by small frame spacing, and a separate setting of rolling and reel temperature.
  • the object is achieved by an aluminum hot strip rolling mill according to claim 1.
  • it is possible to respond in a variety of ways to the cooling process of the aluminum alloy rolled or subsequently coiled in a tandem finish rolling mill or of the aluminum hot-rolled strip consisting of this alloy. This is supported by the use of at least one trimming scissors.
  • a trimming shear can be arranged in the outlet area of the tandem rolling mills. This is advantageous in order to remove the irregular hot strip edges resulting from the process, which may be subject to cracks, and thus to produce a uniform strip edge.
  • These scissors are adjustable and remove about 2 to 150 mm of the band edge. Precision can be eliminated by the band edges defined in this way in order to take into account the temperature gradients at the strip edge resulting from the rolling process. Possible unevenness in the area of the strip edges can thus be avoided, which can be reduced by cooling i.d.R. would strengthen. Furthermore, the width-dependent adjustment of the cooling device is possible in a simple manner by the reliable knowledge of the edged bandwidth.
  • Intermediate cooling in the sense of the invention means a cooling device arranged between two rolling stands of the tandem rolling mill. These can, for example, apply a coolant amount of about 500 l / min up to 15000 l / min to the belt. These large quantities are required to achieve proper cooling in the belt.
  • a cooling device is arranged between the last rolling stand of the tandem rolling mill and the reel means understood. These can apply a coolant amount of about 2000 l / min up to 50,000 l / min to the belt. These large quantities are required to achieve proper cooling in the belt.

  • AA6xxx grades can be subjected to hot recrystallization in the temperature range between 300 ° C to 370 ° C to obtain as uniform a microstructure as possible with good grain refinement, while at the same time reducing the reel temperature to a temperature within the range from below 200 ° C to below 250 ° C can be set to prevent the flow of diffusion processes or slow down significantly and thus to prevent the formation of coarse precipitates by diffusion during coiling or cooling of the aluminum hot strip on the rewinder.
  • the exact, alloy-dependent adjustment of the coiler temperature is essential in that a temperature is set at which diffusion processes no longer take place or only greatly slowed down.

This allows the production capacity of one with such a tandem finishing train equipped, in particular retrofitted, aluminum hot strip rolling mill increase.
  • the retention of hydrous materials on the aluminum strip during winding on the rewinder results in corrosion attack and surface discoloration. Since aluminum strip is not pickled, these surface defects remain and also lead to loss of quality or waste, if this process is not counteracted with the aid of belt drying.
