Definitions

  • the invention relates to a rolling mill arrangement for producing seamless tubes and a method for rolling seamless tubes on this rolling mill arrangement.
  • the different rolling processes have different areas of application. While the push bench is only suitable for small pipe diameters, the vocational mill has its main area of application today in the largest pipe diameters up to 26 ". The stopper mill, on the other hand, is around 16".
  • Another criterion of the rolling process is performance, i.e. the quantity of pipes that can be produced in a certain period of time. This performance and the producible pipe diameter range and the required.
  • Investment costs are important factors for the profitability of a plant. Another important factor are the requirements that the international market places on the manufacturer. For example, In recent years the consumption of oil field pipes has increased significantly. It can also be observed that pipe production is shifting more and more from the traditional export countries to the oil-producing countries. Pipe manufacturing systems are required here that have a relatively low annual output and a low investment volume. These requirements cannot be met with most known rolling processes.
  • the object of the invention described below is therefore to find a tube rolling plant with low investment costs, in which the tube can be produced with a minimum of process steps without intermediate heating.
  • a rolling mill arrangement which is characterized by the arrangement in series of a cross-rolling mill equipped with rotating guide disks for punching, a swing rolling mill equipped with rotating guide disks for stretching and a reduction or sizing mill for finish-rolling the tube.
  • the system can mainly be used very economically for so-called casing pipes, i.e. lining pipes for boreholes.
  • the minimum pipe length is a commercially available single length, but it is also possible to roll double lengths.
  • cross roll mill is equipped with a retracted, retracted rolling rod for stretching the tube.
  • Cross-rolling mills equipped with rotating guide disks were used for the first time instead of the usual fixed guide shoes and proved that relatively thin-walled pipes of good quality can be rolled in this way.
  • Cross rolling mill of this type with axially immovable rolling mandrel had the disadvantage of limited hollow block or section length, because the rolling mandrel quickly heated up to such an extent that overheating caused failures.
  • the rolling rod is tracked at a speed which is lower than the rolling stock outlet speed from the cross-rolling mill.
  • Embodiments of the method can be seen in the fact that the rolling rod after. Completion of the stretch rolling is withdrawn or that the roll rod is withdrawn before the end of the stretch rolling.
  • the slug can be removed in the opposite direction. Because the rod is held back, it can be made correspondingly shorter, which makes it lighter and cheaper.
  • the controlled entrainment of the rod in the cross-rolling mill allows the pipes to be finished without reheating, which also helps to make the rolling mill system cheaper.
  • FIG. 1 shows a descaling device from which the blocks which have been moved laterally are fed to the first cross-rolling mill 3 for punching. After the discharge from the cross-rolling mill 3, the primary material is fed to the second cross-rolling mill 4 for stretching and rolled out again by transverse displacement. 5 is the sizing mill to which the pipe pre-rolled in the cross rolling mill 4 is fed for finish rolling.
  • the cooling bed for the finished pipes is numbered 6.
  • Fig. 2 the cross rolling mill for stretching the tube is shown in plan view.
  • the roller rod 13 is drawn in the retracted position and in the lower half of the drawing in the working position.
  • the actual roll stand is numbered 7
  • the work rolls are indicated at 8. 9 denotes the rotating guide disks.
  • the holding device for the roller rod 13 is indicated, which is guided in the rod bed 11 in the rolling direction.
  • the associated travel drive is numbered 12.
  • the actual working part of the rolling rod bears the position 14.
  • the outlet side of the cross rolling mill is indicated.
