Definitions

  • a method known from German Offenlegungsschrift DE-A-32 41 745 according to the preamble of claim 1 or a system according to the preamble of claim 5 provides for problem solving that the band-shaped casting strand is wound into a bundle and unwound again after heating a rolling mill for rolling out to final cross sections.
  • the rolling mill is designed as a Steckel rolling mill or a finishing stand group of a hot strip rolling mill.
  • the disadvantage of this known system is primarily the high investment costs for a multi-stand tandem mill, the cost of which is well over DM 100 million. Such high costs can only be borne if the Konti-Strplie is fully utilized; therefore it is also proposed in the cited publication to arrange a multi-core continuous casting installation in front of the continuous road. However, this increases the total effort and the output of the entire system, which is not required in many applications.
  • the first two stands work with approximately maximum rolling moment and large work roll diameter.
  • the work rolls are driven.
  • the increase in the gripping angle due to a larger decrease is compensated for by the enlargement of the work roll diameter and by the lowering of the rolling speed, since it is known that the gripping capacity also decreasing rolling speed increases.
  • the drive takes place via the support rollers.
  • Such a mode of operation is particularly useful with very small end cross sections of less than 2 mm.
  • Such a buffer store can be designed both as a storage furnace with transverse displacement of the strip lengths or as a continuous furnace and correspondingly longer.
  • the method for rolling narrow finished strips between 1000 to 2000 mm, preferably 1350 mm wide and with great success for rolling finished strips of low strength is used particularly expediently and advantageously.
  • the object is achieved by the features of claim 5. All work rolls of the rolling mill are advantageously provided with their own drive. Furthermore, the work rolls of the first two stands can be provided with a drive and the third and / or fourth stand can be provided with a support roll drive, in particular if the smallest final thicknesses are to be rolled.
  • (1) denotes a strip or continuous caster, which is followed by a cross-cutting device (2), for example a flame cutting machine or scissors, for separating the cast strip (3) and leaving the strip caster (1) into sections of the same length .
  • the individual partial lengths of the strip (3) are then temporarily stored in a storage and heating device (4), for example a roller hearth furnace, and brought to a homogeneous hot rolling temperature of approximately 1050 to 1100 degrees Celsius.
  • a partial length (5) leaving the furnace (4) is descaled in a known manner and possibly also brought to a new pre-strip length (not shown).
  • the partial strip (5) is then finished rolled in a rolling train (6) consisting of three (or four) stands (6 ', 6 ", 6) from the initial cross section to the final roll thickness.
  • a rolling train (6) consisting of three (or four) stands (6 ', 6 ", 6) from the initial cross section to the final roll thickness.
  • the finished strip (7) passes through the cooling section (8) in order to be subsequently wound up by the underfloor reel (9) at a temperature of approximately 560 degrees Celsius.
  • FIG. 2a an initial thickness of the strip material of 50 mm is assumed for the first stand.
  • the lines of the same work roll diameter (13-17) rise, for example, from bottom to top in the range from 400 to 800 mm.
  • the reference numbers (23-27) in turn indicate increasing work roll diameters as a function of the rolling torque and reduction in thickness.
  • the working point (28) in the permissible range above the line for the maximum transferable rolling moment with work roll drive (22), but outside the permissibility for results in the second stand with preferably the same work roll diameter (between 25 and 26)
  • Back-up roller drive (21) with a reduction in thickness of, for example, 12 mm, so that from 24 to 12 a residual thickness 12 mm remains, corresponding to a related stitch reduction of 50%.
  • the permissible field of work between the lines (22) and (20) is delimited to the right by the line of the maximum gripping angle (29) at the highest stitch decreases.
  • the same increasing work roll diameters are also shown with reference numbers (43-47) depending on the rolling moment and the reduction in thickness.
  • the desired decrease in thickness is, for example, 3 mm with a final thickness of 3 mm, corresponding to a related decrease in height of again 50%.
  • the selected working point (48) is, as in Fig. 2c, far below the maximum transferable rolling torque in the permissible range of the rolling torque lines (41, 42) for work and backup roll drive, so that the work rolls here, as in the third stand, optionally have their own drive own (42) or driven by the support rollers (41).
  • the numbers (73-77) denote the lines of increasing work roll diameters from 400 to 800 mm.
  • the set decrease in thickness is, for example, 4 mm to achieve a remaining thickness of 4 mm, corresponding to a related decrease in height of 50%.
  • the selected working point (78) is 900 kNm with a 4 mm decrease in thickness, far below the maximum transferable rolling torque in the permissible range of the rolling torque line for back-up roll drive (not shown) and work roll drive (72).
