Definitions

  • BESTATIGUNGSKOPIE The invention is therefore based on the object of providing a rolling method and a rolling installation of the type mentioned at the outset, which permit optimized operation with a further reduced outlay on equipment.
  • a 3-roll continuous rolling mill is used in the main stretching stage and is used both for tube rolling and for solid rolling in the production of bars, wire or the like, for which purpose a mandrel bar used for tube rolling in an out-of-operation position is brought and provided steel bar rolls with rolls calibrated for a large diameter reduction are exchanged for the rolls with their rolls calibrated for pipe rolling.
  • continuous rolling mill sometimes also called “continuous tube rolling mill” the person skilled in the art understands a rolling mill consisting of several consecutive rolling stands with an internal mandrel bar, as has become known, for example, from DE-Z "Berg- und Wegtenmännchen Monthly Bulletin 130 (1985) No. 7, pages 205 to 211. "
  • An advantageous embodiment of the method according to the invention provides that a 3-roll cross-rolling mill is also used for the perforating mill upstream of the main stretching stage, the perforated rollers for solid rolling with removed piercing mandrel bar being exchanged for provided steel bar rollers with rollers calibrated for diameter reduction.
  • the 3-roll cross-rolling mill according to the invention in a perforated rolling mill then enables the production of different bar steel diameters in the sense of a pre-reduction, i.e. with a piercing rod moved away for solid rolling. a proportional reduction in cross-section based on the total reduction of all operated rolling mills.
  • the piercing mill also fulfills a universal function.
  • a rolling mill for carrying out the method has a multi-stand 3-roll continuous rolling mill designed to hold steel bar rolls or tube rolls and a device for removing the mandrel bar.
  • the continuous rolling mill or the main stretching stage takes on either the one or the other stands or sets of rolls, each consisting of three rolls, on a frame.
  • Corresponding stands can be provided in addition to the continuous rolling mill, which can then be brought into the operating position after the previous stands have been pulled out of the frame.
  • a cassette construction or the exchange of only the rollers with the scaffold housings remaining in the frame is possible.
  • the mandrel bar can be moved to a non-operating position with the aid of the dome bar holding device when converting the 3-roll continuous rolling mill to solid rolling.
  • This also applies to the perforated dome rod of the cross-rolling mill optionally upstream of the main stretching stage, which according to one embodiment of the invention is also designed as a universally usable 3-roll cross-rolling mill.
  • a preferred embodiment of the invention provides that a speed control is assigned to the 3 ⁇ / valve continuous rolling mill of the main stretching stage. This advantageously enables the different rolling speeds to be achieved in tube and bar rolling.
  • the pull-out rolling mill arranged behind the main stretcher advantageously has two stand units which are arranged at a distance from one another and have end shears which can be inserted between them, bad ends can be easily cut off before further rolling in solid rolling. On the other hand, the use of scissors is not necessary for tube rolling.
  • the pull-out rolling mill is advantageously followed by a reheating furnace. From there, the heat-treated steel bars or, for example, alloyed or unalloyed steel pipes reach the finishing mill. This can include a sizing mill, a reducing mill or a stretch-reducing mill or a combination of these units. If a steel bar is to be rolled into wire, a roller table leading to the wire block is arranged behind the cooling bed.

  • a heated insert block is fed from there to a perforated cross-rolling mill designed as a 3-roll cross-rolling mill 3, where the block is guided in an inlet channel and rolled onto a mandrel bar provided with a piercing mandrel to form a hollow block in preparation for the subsequent rolling out to a seamless one Tube is deformed.
  • a cross roll mill 3 in three-roll construction is known in the manufacture of pipes. If it is not pipes but rods or wire that are to be rolled, the 3-roll cross-rolling mill 3 is used with the mandrel rod held back or removed from the rolling line. massively reducing the block and compacting the structure instead.
  • the hollow blocks or the solid blocks are loaded into the downstream rolling devices.

Insertable end shears 8, 9 are provided both between the multi-stand 3-roll continuous rolling mill 5 and the pull-out rolling mill 6 and between the two stand units 6a, 6b of the pull-out rolling mill 6.
  • a hollow block is stretched in the 6-stand 3-roll continuous rolling mill 5 and, after pulling out the mandrel bar, which is carried out by a back and forth mandrel bar holding device, reduced as a slug in the two stand units 6a, 6b of the pull-out rolling mill 6, while at Solid rolling, even the 6-stand 3-roll continuous rolling mill 5, like the pull-out rolling mill 6, reduces the bar steel by reducing the diameter.

Abstract

L'invention concerne un procédé de production de fil métallique, barres d'acier ou tuyaux sans soudure au moyen d'une installation de laminage conçue pour laminer des matériaux métalliques chauffés, comprenant dans le sens du laminage éventuellement un laminoir perceur à cylindres obliques, un laminoir dégrossisseur à plusieurs cages servant d'étage d'étirage principal (4), un laminoir étireur (6), un lamineur finisseur (10) et un lingot de laminage de fil métallique (15) ainsi que des dispositifs intermédiaires ou disposés en amont ou en aval, tels qu'un four préchauffeur et un four à réchauffer (11), des trains de rouleaux (14) et un lit refroidisseur (13). Un système de laminage continu à 3 cylindres (3) est utilisé dans l'étage d'étirage principal (4), à des fins de laminage pour produire des tuyaux et pour laminer des pièces massives en vue de produire des barres d'acier, du fil métallique ou des éléments analogues. Au cours d'un laminage de pièces massives, un poinçon conçu pour laminer des tuyaux est placé dans une position hors service, et des cylindres pour barres d'acier disponibles, comprenant des cylindres calibrés pour une réduction diamétrale supérieure à la réduction diamétrale habituelle pour un laminage de tuyaux, sont remplacés par les cylindres calibrés pour le laminage de tuyaux. L'invention concerne en outre une installation de laminage permettant d'exécuter ledit procédé et comprenant dans l'étage d'étirage principal (4) un système de laminage continu à 3 cylindres (3), comportant plusieurs cages et conçu pour recevoir des cylindres pour barres d'acier ou des cylindres pour tuyaux, ainsi qu'un système d'éloignement du poinçon.
