Definitions

  • the invention relates to methods and apparatus for rolling rolling in a rolling mill with a cross rolling mill.
  • a generic rolling mill As well as a generic method are, for example DE-A 10 349 056 known.
  • Rolling mills with cross rolling mills are used, for example, to roll metallic seamless tubes or other rolling stock of round cross-section, such as bars.
  • a cross rolling mill In a cross rolling mill several rolls are arranged on the circumference of a rolling stock to be rolled. The rolling stock is rotated between these rolls rotating in the same direction of rotation and thereby formed. In order to obtain a movement of the rolling stock in the longitudinal direction, the rollers are tilted in the tangential plane at a certain angle to the rolling stock longitudinal axis. This arrangement thus ensures a helical movement of the rolling stock.
  • the aforementioned construction of a cross rolling mill has a number of disadvantages, resulting in particular from the rotation of the rolling stock about its longitudinal axis. These are in particular the limitation of the maximum rolling stock length, complex bearings and guiding devices and a low throughput speed. For the quality of the rolling stock fluctuations in the rotation of the rolling stock are disadvantageous.
  • German patent 195 10 715 C2 describes such a planetary cross rolling mill.
  • the construction of the device DE 195 10 715 C2 has a rotor driven via a main drive, which encloses the rolling stock and in which four planetary rollers are rotatably mounted. These planetary rollers rotate as such with the rotor.
  • the planetary rollers are rotationally driven by an auxiliary drive about their longitudinal axis.
  • a longitudinal rolling mill or another planetary cross rolling mill can be arranged downstream.
  • the invention has for its object to propose a method and an apparatus which avoid the above-mentioned disadvantages and which allow efficient rolling.
  • the invention is based on the basic idea that rolled material, at least during a period of time, both simultaneously in the planetary cross-rolling mill and in the subsequent rolling mill to roll on a mandrel bar.
  • the invention provides a mandrel bar which has a length which is greater than the distance between the planetary cross rolling mill and the further rolling mill in the rolling direction and in particular is greater than the hollow block length. It is desirable that the mandrel bar is long enough to engage at least one set of rolls of the downstream rolling mill when the tube leaving the planetary cross rolling mill arrives at that same set of rolls. The mandrel engages when the wall thickness of the pipe is reduced by the rolls of the respective rolling mill on the mandrel.
  • the invention makes it possible to distribute the forming work better on the two rolling mills.
  • the planetary cross rolling mill can now be used to roll a precursor, on the accuracy of lower requirements can be made.
  • the exact finish rolling then takes place in the downstream rolling mill.
  • This procedure also makes it possible to make a roll change less frequently in the planetary cross rolling mill.
  • the wall thickness can be adjusted to the desired level without conversion measures.
  • this allows to keep for the planetary cross rolling mill only single, fixed Domstangen trimmesser and make the transformation of the rolling stock on any intervening cross section through the further rolling mill.
  • the number of mandrel bar changes can be reduced, whereby the time utilization is improved.
  • the stretch of the rolling stock can be distributed to both stands, so that higher rolling speeds are achieved in the finishing mill.
  • a rolling plant for rolling of rolling stock with a planetary cross rolling mill and a following in the rolling direction further Rolling mill on a mandrel bar, which has a length which is greater than the distance between the planetary cross-rolling mill and the further rolling mill in the rolling direction and in particular preferably longer than the hollow block length.
  • the distance between the planetary cross rolling mill and the further rolling mill in the rolling direction the distance between the point of the planetary cross rolling mill at which the rolling stock is engaged with the rollers of the planetary cross rolling mill for the last time and the point at which the rolling stock is for the first time in engagement with the first rolls of the further rolling mill, understood.
  • the mandrel rod can - as desired according to the invention - pass through the rolling stock, while it is the rolling stock both in the nip of the planetary cross rolling mill and in the nip of the other rolling mill.
  • a holder for the mandrel rod which can hold the mandrel in a position in which the mandrel passes through the nip of the planetary cross rolling mill and at the same time at least partially projects into a nip of the further rolling mill.
  • the holder is provided on the side facing away from the further rolling mill of the planetary cross rolling mill.
  • a linear drive for linear method of holding the mandrel is provided.
  • the planetary cross rolling mill in the rolling direction is subsequently arranged a longitudinal rolling mill.
  • a longitudinal rolling mill is understood in particular to mean a rolling mill with rolls whose axes are arranged parallel to one another and / or in each case perpendicular to the rolling direction.
  • the mandrel bar is formed in several parts.
  • the mandrel has different diameters in a preferred embodiment. If the mandrel bar is of a multi-part design, the diameter change along the longitudinal axis of the mandrel bar can be easily adjusted, for example by removing a smaller diameter section and attaching a mandrel bar section with a slightly larger diameter to the remaining part of the mandrel bar.
  • a measuring device for determining the rotation of the rolling stock is arranged between the further rolling mill and the planetary cross rolling mill.
  • the further rolling mill is a longitudinal rolling mill, in which the rolling stock is to be rolled almost free of rotation
  • the planetary cross rolling mill has a main drive for rotating a rotor comprising the rolling stock and planetary rollers rotatably mounted in the rotor. Furthermore, the planetary cross rolling mill of the preferred embodiment has an auxiliary drive for rotating the planetary rollers about their longitudinal axis. For a preferred construction of a planetary cross rolling mill is also on the DE 195 10 715 C2 directed.
  • the planetary cross rolling mill preferably has three or more planetary rollers, in particular four planetary rollers.
  • the rolling stock is during a time interval during rolling both in the nip of the planetary cross rolling mill and in the nip of the further rolling mill.
  • the rolling stock is located during the major part of the rolling both in the nip of the planetary cross-rolling mill and in the nip of the other rolling mill.
  • the rolling stock is only during the unavoidable start-up and shut-down phase either only in the nip of the planetary cross-rolling mill or in the nip of the other rolling mill.
  • a mandrel passes through the rolling stock, while the rolling stock is both in the nip of the planetary cross rolling mill and in the nip of the other rolling mill, wherein the mandrel has a length which is greater than the distance between the planetary cross rolling mill and the further rolling mill in the rolling direction ,
  • the method according to the invention is preferably used for rolling tubular rolling stock into so-called lumps.
  • the rolling stock is preferably metallic, but may also be of other material, for example plastic.
  • the inventive method and the rolling mill according to the invention are particularly well suited for rolling particularly thin-walled rolling stock.
  • Fig. 1 is a rolling mill, consisting of a planetary cross rolling mill 20, a longitudinal rolling mill 25 and a measuring device 8 arranged therebetween shown.
  • a mandrel 10 is held in a holder 11.
  • a linear drive 12 can move the holder 11 linearly.
  • the mandrel bar 10 has a length which is greater than the distance between the planetary cross rolling mill 20 and the longitudinal rolling mill 25.
  • the rolling stock 6 is rolled on a mandrel bar both in the planetary cross rolling mill 20 and in the longitudinal rolling mill 25.
  • the planetary cross rolling mill 20 consists of several planetary rollers 1, which roll with their lower portions on the rolling stock 6.
  • the planetary rollers 1 are inclined relative to the longitudinal axis of the rolling stock 6 both in the vertical and in the horizontal plane.
  • the planetary rollers 1 are rotatably mounted at their rear end in a rotor 2, whose axis of rotation coincides with the longitudinal axis of the rolling stock.
  • the rotor 2 is driven via a transmission from the output shaft 3 of a main drive.
  • the rotor 2 and the planetary rollers 1 mounted in it perform a rotary movement about the rolling stock 6.
  • the sun gear 5 is driven via a transmission of the output shaft 7 of a superposition drive (auxiliary drive). This rotational movement of the sun gear leads to a superimposed rotation of the planetary rollers 1, which results from the sum of the two rotational movements.
  • a rolling without a rotary movement of the rolling stock 6 can take place.
  • the necessary ratio between the rotational speeds of the rotor 2 and the planetary rollers 1 changes during the rolling progress due to varying parameters, such as area changes in the material properties of the rolling stock, temperature fluctuations, scale deposits or changes in the furnacenreibute.
  • a measuring device 8 is arranged, which detects the possibly caused by parameter changes rotational movements n tube of the rolling stock 6 and passes on to a computer that controls the drives of the planetary cross rolling mill 20 so that rotation of the tube is avoided.
  • Fig. 2 shows the rolling mill in the so-called “rolled out” state in which the mandrel bar 10 protrudes at the end of the longitudinal rolling mill 25.
