Definitions

  • the invention relates to a process and a plant for carrying out the process for producing hot-rolled aluminum strip for can making, especially in rolling plant whose yearly production capacity is below 250,000 tons, having a reversing roughing stage for the feed material, which is used hot, and immediately thereafter finishing rolling of the strip, which is followed by heat treatment of the strip coiled up into coils.
  • the other process which is practiced for producing aluminum strip for can making provides for a reversing rolling mill having coilers arranged on both sides for the finishing rolling of the strip.
  • the process has the disadvantage that a nonuniform temperature distribution over the length of the strip is established during the winding and unwinding of the strip, and therefore the desired uniform structure development in the unrolled coil cannot be achieved.
  • intermediate annealing is carried out during the subsequent cold-rolling process, and although this improves somewhat the capability of the aluminum strip for can making to be deep drawn, it does not develop the cubic texture in the strip material which is beneficial for the deformation operation.
  • the object of the present invention is to provide a practicable and economic solution for the production of high-quality strip for can making on hot-rolling mills with a yearly capacity below 250,000 tons, in which the cubic texture which is beneficial for the reshaping of the aluminum strip is developed.
  • a finishing rolling mill of this type comprises an individual reversing roll stand with coilers arranged on both sides, so that, in the first place, the high investment costs for the four-high finishing roll stands of a multi-stand rolling train are dispensed with. Since the temperature management and the rolling and pause times—especially in the case of minimill concepts—are critical, the invention provides for the strip to be rolled in the noncritical range from 260° C. to 280° C.
  • a furnace of this type only has to apply the temperature difference of about 40°-60° C. between the rolling temperature and the recrystallization temperature, and thus achieves a favorable energy balance. Annealing before or during the cold-rolling can be dispensed with as a result of the process of the invention.
  • the structure (the cubic texture) corresponds to the product produced on multi-stand hot-strip finishing rolling mills, without the high investment needed there being required.
  • a plant for carrying out the process according to the invention is defined in that the finishing rolling is carried out on a four-high reversing roll stand with winding devices arranged on both sides, in that one of the winding devices corresponds to a coil transport device for the finished coil and, on the other side, is connected to a continuous pusher-type furnace for coils, into which the coils can be introduced.
  • the plant therefore essentially comprises two reversing roll stands, one of which, as the roughing roll stand, roughs the block, heated to the rolling temperature, in the conventional way, and the second reversing roll stand having coiler devices arranged on both sides is provided, in which the strip is wound and unwound in a number of reversing passes, in each case forming coils.
  • the finished coil is transferred by a coil transfer device to the coil transport device, with which the finished coil is transported to an adjacent continuous pusher-type coil furnace. After it has been introduced into the continuous pusher-type coil furnace, the coil is heated to recrystallization temperature outside the rolling train, so that the desired structure is obtained.
  • the continuous pusher-type coil furnace is preferably equipped with a pallet transport system, in which a number of pallets in contact with one another at the ends and holding the coils can be transported through the furnace by displacing these pallets.
  • a pallet transport system in which a number of pallets in contact with one another at the ends and holding the coils can be transported through the furnace by displacing these pallets.
  • Such pallet transport systems are known per se; by means of the cyclic displacement of the first pallet by means of a displacement device, for example a hydraulic cylinder, the pallets located in a row one behind another are in each case displaced at the same time, so that as each pallet loaded with a coil is introduced into the furnace, a pallet with a finished, heat-treated coil is ejected on the discharge side of the continuous pusher-type coil furnace. After cooling, the coil is fed to the cold-rolling mill, without any further heat treatment having to be carried out.
  • the single drawing FIGURE depicts a rough, schematic illustration of a plant according to the invention. It comprises the four-high reversing roll stand 1 , the four-high reversing finishing roll stand 2 following in the rolling direction, and the continuous pressure-type coil furnace 3 .
  • the feed material, used at 4 in the form of a heated aluminum block, is rolled out, as indicated at 5 , in a number of reversing passes in the four-high rolling stand 1 of the roughing rolling train to form a rough strip 6 , and is immediately introduced into the finishing rolling train comprising the four-high reversing roll stand 2 .
  • the rough strip 6 is rolled out in a number of reversing passes 7 to form a finished strip, the strip being coiled up on either side of the four-high reversing roll stand 2 after each rolling pass, as indicated at 8 and 9 .
  • At least three hot-rolling passes in accordance with this procedure are preferably provided.
  • the coil B wound up at 9 is transferred by a transfer device (not illustrated) to a coil transport device, indicated at 10 , which transports the coil B to the continuous pusher-type coil furnace 3 .
  • a transfer device not illustrated
  • a coil transport device which transports the coil B to the continuous pusher-type coil furnace 3 .
  • the coil B is deposited on a pallet 11 , of which a large number of identical pallets 11 can be displaced through the continuous pusher-type coil furnace 3 .
  • the pallet 11 with the coil B is pushed into the furnace with the furnace door 3 a open and, at the same time, a pallet 13 with a completely, heat-treated coil B is ejected at the end of the continuous pusher-type coil furnace 3 through the furnace door 3 b , which is likewise open.
  • a number of pallets 11 which are in contact with one another at the ends and have an identical number of coils B which, during their passage through the continuous pusher-type coil furnace 3 , are heated to a temperature above the recrystallization temperature of the aluminum strip, that is to say about 315-320° C.
  • the reversing rolling passes 7 in the four-high reversing finishing roll stand 2 were carried out at a temperature below the recrystallization temperature of about 260-280° C.
