Definitions

  • the invention relates to a rolling mill, in particular to a high-precision new six-roll hot-rolled strip mill. Background technique
  • the structure of the hot-rolled strip mill adopts a small work roll and a large support roll.
  • the rolling force is transmitted to the support roll through the work roll.
  • the strength of the roll system mainly depends on the strength of the support roll, and the rigidity of the rolling mill depends on the machine.
  • the rigidity of the frame and the roll system, to roll out high-precision hot-rolled strips requires a complex system to support.
  • An object of the present invention is to provide a high-precision hot-rolled strip mill which is suitable for rolling all hot-rolled strips, and which solves the problem that the ultra-wide strip mill equipment is difficult to manufacture.
  • the technical solution adopted is:
  • a hot-rolled strip mill includes a frame, upper and lower roll holders, upper and lower rolls, and a pressing device for adjusting the roll gap of the work roll, the upper and lower rolls each including a work roll and two support rolls,
  • the utility model is characterized in that the work roll and the support roll form a triangle, and the outer support roll diameter is smaller than the inner work roll diameter.
  • the above-mentioned pressing device acts on the work roll through the upper roll holder.
  • the roller body and the pressing device of the above-mentioned support roller are supported by a backing bearing.
  • the present invention has the following advantages over conventional hot rolled strip mills:
  • the rolling mill does not need a series of rolls, bending rolls and other means, can achieve higher rolling accuracy, lateral error is less than 10
  • the mill has low operating cost and long roll life. It does not require huge roll lathes and grinding machines, and the plant cost is also reduced accordingly. 4.
  • the rolling mill has a wide application range, which solves the difficult problem of making ultra-wide strip mill equipment. It can roll strips with a width of 8000mm or less, and its structural form can completely eliminate the traditional hot-rolled strip mill.
  • FIG. 1 is a schematic view showing the structure of an embodiment of the present invention.
  • a hot rolled strip mill of the present invention comprises a frame 6, an upper roll stand 4, a lower roll stand 7 and upper and lower roll trains.
  • the upper and lower rolls each include a work roll 2 and two support rolls 3, and the outer side of the work roll 2 is in contact with the inner sides of the two support rolls 3, and the inner work roll 2 has a larger diameter than the outer two support rolls 3.
  • the diameter of the rolled piece 1 is sandwiched between the work rolls 2 of the upper and lower rolls.
  • a pressing device is disposed between the upper roller holder 4 and the frame 6, and the pressing device is well known to those skilled in the art, so that the expansion device 5 can be used to adjust the size of the work roll gap.
  • the maximum rolling force experienced by the non-transmission roller is mainly determined by the maximum bending stress that the roller can withstand.
  • the maximum bending stress that the roller can withstand can be It does not constitute a limitation of the strength of the roll, and the work roll in the middle mainly satisfies the transmission problem.
  • the conventional bulk support roll is replaced by two small support rolls, which greatly saves the roll material.
  • the invention provides a high-precision hot-rolled strip mill, which is suitable for rolling all hot-rolled strips, and solves the problem that the ultra-wide strip mill equipment is difficult to manufacture.

Abstract

Un laminoir multicylindre pour laminage à chaud de bande et de plaque comprend un logement, des assises de cylindres supérieure et inférieure, des systèmes de cylindres supérieur et inférieur et un dispositif à vis de réglage permettant de régler la distance entre les cylindres de travail, les systèmes de cylindres supérieur et inférieur comprenant chacun un cylindre de travail et deux cylindres d’appui, les cylindres de travail et les deux cylindres d’appui des systèmes de cylindres supérieur et inférieur formant un triangle, et le diamètre externe des cylindres d’appui étant inférieur au diamètre interne des cylindres de travail. L’invention présente des avantages par rapport au laminoir conventionnel pour laminage à chaud de bande et de plaque, à savoir:1.suppression des systèmes de cylindres d'appui massifs et résolution complète du problème de flexibilité des cylindres pendant le laminage à chaud de bande et de plaque;2.suppression du besoin d’un moyen de déplacer les cylindres ou de cintrer les cylindres, ceci permettant d’obtenir une précision de laminage plus grande avec moins de 10μvm/m d’erreurs transversales ;3.baisse des coûts d’exploitation du laminoir, rallongement de la durée de vie des cylindres, suppression du besoin de tours massifs et d’une meule pour cylindres, entraînant une réduction des coûts de fabrication pour l’installation ; 4.la palette d’application du laminoir est très large, ce qui résout la difficulté liée à la fabrication du laminoir pour bande et plaque super large, permettant ainsi de laminer une bande et une plaque d’une largeur inférieure ou égale à 8000 mm, et la structure de celui-ci peut remplacer complètement le laminoir conventionnel pour laminage à chaud de bande et de plaque.
