Definitions

  • Process and plant for the production of hot-rolled AI can strip
  • the invention relates to a method and a plant for carrying out the method for producing hot-rolled Al-can strip, especially in rolling mills, whose annual production capacity is below 250,000 tons, with a reversing roughing of the raw material used hot and immediately subsequent finishing rolling of the strip, which is a heat treatment of the coiled reel follows.
  • Pre-rolled reversing stand and then finish-rolled on a multi-stand mill Pre-rolled reversing stand and then finish-rolled on a multi-stand mill.
  • Four-high mill stands are usually used in the finishing train, whereby care must be taken to ensure that constant temperature conditions are maintained within the mill so that the strip that is coiled up into a bundle is given the desired optimal rolling structure.
  • a reel temperature of approx. 320 ° C should be aimed for.
  • the finished rolled Al strip is given the structure with cube texture which is known in specialist circles and which is particularly well suited for deep-drawing aluminum cans due to its low tip formation.
  • the other practiced method for the production of aluminum can strip provides a reversing rolling mill with reels arranged on both sides for the final rolling of the strip.
  • the method has the disadvantage that there is an uneven temperature distribution over the length when the tape is wound up and unwound of the strip and therefore the desired even structure in the rolled out bundle cannot be achieved.
  • an intermediate annealing is carried out in the subsequent cold rolling process, which improves the deep-drawing ability of the aluminum can strip somewhat, but does not form the cube texture in the strip material that is favorable for the deformation process.
  • the aim of the present invention is to provide a practicable and economical solution for producing high-quality canned strip on hot rolling mills with an annual capacity of less than 250,000 tons, in which the cube texture which is favorable for forming the Al strip is formed.
  • the last, preferably three, hot rolling passes of the finishing train on a reversing roll stand from bundle to bundle are not recrystallized in the uncritical temperature range from 260 ° C. to 280 ° C. and each coiled finished bundle is fed to a bundle piercing furnace immediately afterwards and using the rolling heat in which the finished bundles on
  • Recrystallization temperature (315 320 ° C) are heated.
  • the last three hot rolling passes are carried out from bundle to bundle on a finishing mill especially for a minimill concept.
  • a finishing mill consists of a single reversing roll stand with reels arranged on both sides, so that initially the high investments for the four-high finishing stands of a multi-stand mill are eliminated. Since the temperature control and the rolling and pause times are critical, especially in the case of minimill concepts, the invention provides for the strip to be rolled in the uncritical range from 260 ° C. to 280 ° C. and only then and using the rolling heat in a subsequent furnace to the recrystallization temperature to warm up.
  • Such an oven then only has to apply the temperature difference of approx. 40 ° -60 C between the rolling temperature and the recrystallization temperature and thus achieves a favorable energy balance.
  • An annealing during or before cold rolling can be omitted by the method according to the invention.
  • the microstructure (the cube texture) corresponds to the product produced on multi-stand hot strip finishing mills without the high investments required there.
  • a system for carrying out the method according to the invention is characterized in that the finish rolling is carried out on a four-high reversing stand with winding devices arranged on both sides, that one of the winding devices corresponds to a coil transport device for the finished coil, which is connected to a coil piercing furnace, into which the coil is fed Heat treatment can be introduced.
  • the system thus essentially consists of two reversing stands, one of which, as a roughing stand, pre-rolls the block heated to the rolling temperature in a conventional manner, and that second reversing stand is provided with reel devices arranged on both sides, in which the strip is wound up and unwound into bundles in several reversing stitches.
  • the finished coil is transferred to the coil transport device with a coil transfer device, with which the finished coil is transported to an adjacent coil piercing furnace.
  • the introduction of the bundle piercing furnace is carried out to heat the bundle to the recrystallization temperature outside the rolling mill so that the desired structure is obtained.
  • the collision piercing furnace is preferably equipped with a pallet transport system in which a plurality of pallets which are arranged on the end face and receive the bundles can be transported through the furnace by moving these pallets.
  • pallet transport systems are known per se; by the cyclical shifting of the first pallet by means of a shifting device, for example a hydraulic cylinder, the row of pallets behind it is also shifted, so that with each pallet inserted into the furnace and covered with a collar, a pallet with a finished heat-treated collar on the discharge side of the Collision piercing furnace is ejected. After cooling, the coil is fed to the cold rolling mill without the need for further heat treatment.
  • a roughly schematic representation of a plant according to the invention is shown in the single drawing figure. It consists of the four-high reversing stand 1, the four-high reversing finishing stand 2 following in the rolling direction and the coil piercing furnace 3.
  • the raw material used in the form of a heated aluminum block at 4 is, as indicated at 5, rolled out in several reversing stitches in the four-high stand 1 of the roughing train to a preliminary strip 6 and immediately thereafter inserted into the finishing train consisting of the four-high reversing stand 2.
  • the preliminary strip 6 is rolled out into a finished strip in several reversing stitches 7, the strip being wound up on both sides of the four-high reversing stand 2 after each rolling pass, as indicated at 8 and 9.
  • At least three hot rolling passes are preferably provided according to this procedure.
  • the coil B wound at 9 is transferred from a transfer device, not shown, to a coil transport device, indicated at 10, which transports the coil B to the coil piercing furnace 3.
  • a coil transport device indicated at 10
  • the collar B is placed on a pallet 11, of which a large number of similar pallets 11 can be moved through the collar piercing furnace 3.
  • the pallet 1 with the collar B is pushed into the furnace with the furnace door 3a open, and at the same time a pallet 13 with a heat-treated collar B is ejected through the likewise opened furnace door 3b at the front end of the collar piercing furnace 3.
  • inside the furnace there are end-to-end pallets 11 with an equal number of bundles B which, when passing through the bundle piercing furnace 3, reach a temperature above the recrystallization temperature of the aluminum strip, i.e. 315-320 ° C.
  • the reversing rolling passes 7 were carried out in the four-high reversing finishing stand 2 at a temperature below the recrystallization temperature of approx. 260-280 ° C.

Abstract

La présente invention concerne un procédé de fabrication de bande d'aluminium pour boîtes de conserve, notamment dans des installations de laminage dont la capacité de production annuelle est inférieure à 250.000 unités, avec dégrossissage en mode réversible de la matière brute, avec enchaînement direct par la passe finale de laminage, suivie d'un traitement à chaud de la bande, qui est dévidée en rubans. Lors des derniers points de la passe finale de laminage, on régule la température de la bande à chaud pour empêcher la recristallisation dans la matière en laminage, ladite recristallisation étant provoquée de manière ciblée tout de suite après la passe finale de laminage. L'invention concerne en outre une installation pour la mise en oeuvre du procédé en question.
