Definitions

  • the invention relates to a method for avoiding changes in shape in metal coils, in particular for avoiding a collapse of freshly wound hot coils, which collapse can occur, for example, in the manufacture of steel products such as metal strips in hot rolling mills or hot rolling mills.
  • a phase transformation of the steel product can occur not only in a cooling section of a hot rolling mill, but also - following the cooling section - in a reel (in which the steel / Metal strip following a rolling step / rolling process - freshly wound - is wound into a hot coil or coil), during a transport - the freshly wound and drawn off the reel (and possibly already bound) hot coil - to a bundle store or in a bundle store Hot rolling mill (in which the freshly wound hot coil is stored) occur (“delayed phase transition”), especially for those grades that will subsequently be cold-rolled.
  • Phase changes in the product such as the metal bundle or the freshly wound hot bundle, in turn lead to changes in volume and changes / deviations in shape ("collapse") there, which are undesirable and / or which lead to serious problems, in particular when bundles are transported and in further processing plants (for example there when winding on a reel mandrel).
  • a special form of this collapse in a steel product is what is known as "ovalization", in which - here in a metal / hot coil or coil - a change in shape / deviation from an initial (approximately) round shape to an oval shape takes place.
  • metal strips with such special steel grades e.g. high-carbon steels, press-hardened steels or multi-phase steels, or in the production of such metal strips, it can lead to the delayed phase transformation and thus to the change in volume, especially during reeling or during coil transport, where the metal strip is present as a (wound) coil or coil Change in shape of the product or coil / coil, d. H. the (undesired) collapse or ovalization.
  • a device for the transport of very heavy metal band coils produced following rolling processes by winding up rolled metal strips.
  • This device comprises pallets used in a circulating system and roller tables that convey these further.
  • a pallet consists of longitudinal beams that are spaced apart from one another and a collar support saddle that bridges these and has opposite supports that include a support bracket.
  • the pallet for transporting a bundle is designed with contours that compensate for vertical and horizontal deformation, at least on its side members, which are precalculated under load and heat.

  • a parameter which determines the duration of the pause or the duration / phase of rest can also be a size, a circumference, a diameter Weight and / or a temperature of the metal bundle, in particular of the freshly wound hot bundle, and / or a thickness of the metal strip wound to form the metal / hot bundle.
