Definitions

  • the invention relates to a rolling stand and a method for adjusting the rolling stand for the rolling operation.
  • Roll stands usually consist of two roll stands with a controllable roll adjustment and an auxiliary setting to achieve a constant pass line. Due to the construction conditions, the stand window laces when Walzkraftbeierschlagung. At different rolling forces are in the stand window before different games between the roll stand and roll chocks.
  • a universal rolling mill consisting of a closed frame for the vertical rolls and chocks for the horizontal rolls, which are supported on upper and lower trusses.
  • the traverses are connected by traction spindles, which pass through the frame and are axially fixed and rotatably mounted therein, so that they - and thus the horizontal rollers - can be adjusted centrally to the rolling or pass line.
  • the frame sits directly on the base plate of the foundation.
  • a rolling stand which comprises four column columns which are firmly anchored to a base plate and in which axially non-displaceably guided, rotatably mounted tension spindles are arranged, whose upper and lower ends are provided with opposite threads, which receive an upper and lower traverse and are adjustable in opposite directions to each other through the sets of rollers exists.
  • the stand columns serve as guides for roll chocks, between the lower backup roll mounting kit and the lower crosshead are arranged short-stroke Ansteilzylinder Walzkraftbeetzschlagung.
  • the invention has for its object to provide a new design principle for rolling mills, which are always set to a constant pass line without other tools.
  • the rolling stand consisting of four column columns, which are firmly anchored with a sole plate and in which axially immovable guided, rotatably mounted tension spindles are arranged, whose upper and lower ends are provided with opposing threads that receive an upper and lower Traverse and on the the roller sets are adjustable in opposite directions, wherein the column columns serve as guides for roll chocks and the inclusion of bending blocks, and arranged between the lower back-up roller assembly and the lower traverse short-stroke Anstellzylinder for Walzkraftbeetzschlagung, wherein by a separate arrangement of the traction spindles and the roll chocks in the stator columns to achieve a separation of the power transmission to the rollers and the leadership of the roll chocks.
  • the object is achieved by a method for adjusting the roll stand with the features of claim 5.
  • the invention is based on the operation of a right and left thread opposite parts evenly (or non-uniformly) to move toward or away from each other.
  • the function of transferring the rolling force is separated from the function of "guide of the roll chocks", whereby disadvantages, such as roll stand window constriction, no longer occur.
  • disadvantages such as roll stand window constriction
  • the construction consists essentially of four welded column columns 1, which take over the leadership of the roll chocks 2 and the inclusion of the traction spindles 3.
  • the column columns 1 are connected to the foundation, i. cast the base plate 6 and secured by anchor bolts.
  • the design for the rigidity is carried out according to the expected loads by the roll chocks 2.
  • the traction spindles 3 with their right and left threads are moved in the unloaded mill stand on position. Only then, the rolling force is adjusted via a short-stroke adjusting 7 and - as stated - introduced in the operating state on the traverses in the tie rods.
  • the design is based on the expected max. Rolling forces.
  • the self-locking in rolling operation is ensured by the small pitch in the thread, which additionally can be secured by a brake in the adjustment position.
  • In the short stroke - Anstellzylinder 7 opposite upper cross member 4 may be installed for smaller Anstell concept nor an additional small Anstellzylinder (not shown).
  • the traction spindles 3 are driven by four synchronized individual drives or by a drive with mechanical synchronization.
  • the upper and the lower traverse 4 and 5 move depending on the direction of rotation of the traction shafts towards or away from each other.
  • the AW always adjusts to the pass line for the same roller diameter (StW, ZW, AW).
