Definitions

  • the invention relates to a method and a plant for the production of hot-rolled steel strip from a strip-shaped, continuously cast starting material in successive working steps, the strip-like starting material being brought to a hot rolling temperature after solidification and being introduced into a multi-stand rolling mill for rolling out into finished strip.
  • the strip-shaped primary material cast as a strand generally has a thickness in the range between 25 and 60 mm.
  • a casting speed of about 0.13 m / s with an average strip thickness of 40 mm and assuming that the strip is to be rolled down to 2 mm this means a twenty-fold change.
  • the casting speed is equal to the entry speed into the first stand, would result in an exit speed of 2.67 m / s after the last stand in a tandem mill with seven stands.
  • the minimum exit speed at a final rolling thickness of 2 mm is approximately 10 m / s, because at lower speeds an excessive decrease in temperature makes rolling impossible. So far, two approaches have been taken to solve these problems.
  • a method known from German Offenlegungsschrift 32 41 745 provides for solving the problem that the band-shaped casting strand is wound up into a bundle and unwound after heating is fed to a rolling mill for rolling out to final cross sections.
  • the rolling mill is designed as a Steckel rolling mill or finishing stand group of a hot strip rolling mill.
  • the disadvantage of this known system is primarily the high investment for a multi-stand tandem line, the cost of which amount to 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 caster on the Konti-Strplie. However, this increases the total effort and the output of the entire system, which is not required in many applications.
  • the object is achieved for the method according to the invention in that the rolling out to finished strip is carried out continuously in a maximum of three or four roll stands with the highest possible pass reductions, without additional expenditure for other facilities being necessary, the same decrease as with the three to four stand streets is achieved with a conventional six- to seven-stand road.
  • the investment costs for the Kontistrasse can be significantly reduced, while at the same time adapting the technologically given rolling speed to the casting speed.
  • the first two stands work with approximately maximum rolling torque and a 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 increases with decreasing rolling speed.
  • the drive takes place via the support rollers. This is particularly the case with very small end cross sections of less than 2 mm Operation makes sense.
  • 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 rolling mill consists of three or four rolling stands. 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. It is particularly expedient for all work rolls of the rolling mill to have the same roll diameter. With this measure, the cost of warehousing can be minimized.
  • (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 belt (3) are then temporarily stored in a storage and heating device (4), for example a roller hearth furnace, and are stored in a homogeneous manner Hot rolling temperature brought from about 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 mill (6) consisting of three (or four) stands (6 ⁇ , 6 ⁇ , 6 ′′′) from the initial cross section to the final rolling thickness.
  • a rolling mill (6) consisting of three (or four) stands (6 ⁇ , 6 ⁇ , 6 ′′′) from the initial cross section to the final rolling thickness.
  • the finished strip (7) passes through the cooling section (8), in order to then be wound up by the underfloor reel (9) at a temperature of about 560 degrees Celsius to become.
  • Figures 2a to 2d schematically show the pass reductions and rolling parameters in four stands, the thickness decrease “ie” of the rolling stock in mm being shown on the abscissa and the sum of the effective rolling moment "Ma" in kNm on the ordinate.
  • 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 of 400 up to 800 mm.
  • the related thickness or stitch reduction reaches a value of 52%.
  • the reference numbers (23-27) in turn indicate increasing work roll diameters as a function of the rolling torque and reduction in thickness.
  • the maximum working area between lines (22) and (20) is limited by the line of the maximum gripping angle (29) at the highest stitch decreases to the right.
  • the reference numbers (33-37) in turn indicate increasing work roll diameters as a function of the rolling moment and the decrease in thickness.
  • the set thickness reduction is here for example at 6 mm with a remaining thickness of 6 mm, corresponding to a related decrease in height of 50%.
  • the selected working point (38) lies far below the maximum transferable rolling torque in the permissible range of the rolling torque line for backup roller drive (31), so that the work rollers can either be driven themselves (32) or indirectly via the backup rollers (31).
  • 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 permissible working field between lines (52) and (50) is not limited by the line of the maximum gripping angle (59).
  • the reference numerals (63-67) in turn indicate increasing work roll diameters as a function of the rolling moment and the decrease in thickness.
  • the permissible working area between lines (62) and (60) is limited by the line of the maximum gripping angle (69) for high stitch decreases to the right.
  • 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 reduction 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).
