Definitions

  • the invention relates to a method and Plant for the production of hot-rolled steel strip from a strip-shaped continuous cast Primary material in successive steps, the band-shaped primary material after solidification brought to hot rolling temperature and for rolling into finished strip in a multi-stand Rolling mill is introduced.
  • the strip-shaped primary material cast as a strand generally has a thickness in the range between 25 to 60 mm. For example, if you go from a casting speed of about 0.13 m / s with an average strip thickness of 40 mm and assumes that the strip is rolled down to 2 mm is to be twenty times Change. In continuous operation, provided that the casting speed is the same the speed of entry into the first stand, would look at a tandem mill with seven scaffolds an exit speed after the last one Scaffolding at a height of 2.67 m / s. The minimum exit speed with a final rolling thickness of 2 mm is approximately 10 m / s, too big at lower speeds Temperature decrease rolling impossible makes. So far, to solve these problems followed two paths.
  • the object of the present invention is therefore a process for producing hot rolled Steel belt and a belt caster with to present downstream hot strip mill, which avoids the disadvantages mentioned and the Difficulties can be overcome and which is economical even with smaller production quantities, i.e. worked at high capacity can be and especially low investment costs required are.
  • the task is solved for the method according to the invention by the features of claim 1.
  • the investment costs for the Contistrasse can even be considerable in this way be lowered while adjusting the technologically given rolling speed the casting speed.
  • the invention it is provided that in the first two stands with approximately maximum rolling moment and large work roll diameter is worked.
  • the work rolls driven.
  • the increase in the gripping angle as a result The decrease is greater due to the enlargement of the work roll diameter and through compensates for the reduction in rolling speed, since it is known to have a grip decreasing rolling speed increases.
  • the primary material cached before introduction to the rolling mill becomes.
  • the strip caster and the hot strip mill be optimally adjusted.
  • Such a Buffer can be used both as a storage heater with transverse displacement of the part lengths or as a continuous furnace and correspondingly longer be trained.
  • Figure 1 with (1) is a strip or continuous caster referred to, the cross-dividing device (2), for example a flame cutting machine or scissors, to separate the cast and the strip caster (1) leaving the strip (3) in Sections of the same length is connected.
  • the individual partial lengths of the tape (3) are then in a storage and heating device (4), for example, a roller hearth furnace, cached and to a homogeneous hot rolling temperature brought from about 1050 to 1100 degrees Celsius.
  • a partial length leaving the oven (4) (5) is descaled in a known manner and if necessary also brought to a new opening length (not shown).
  • the sub-band (5) in a rolling mill (6) consisting of three (or four) scaffolds (6 ', 6' ', 6' '') from the initial cross section Rolled to final roll thickness.
  • a rolling mill (6) consisting of three (or four) scaffolds (6 ', 6' ', 6' '') from the initial cross section Rolled to final roll thickness.
  • the finished belt (7) passes through degrees Celsius Cooling section (8), then from the underfloor reel (9) at a temperature of about 560 degrees Celsius to be wound up.
  • the stitch decreases are shown in FIGS. 2a to 2d and rolling parameters in four stands schematically shown, each on the abscissa the decrease in thickness "ie" of the rolling stock in mm and on the ordinate the sum of the effective Rolling moment "Ma” is specified in kNm.
  • FIG. 2a there is an initial thickness for the first framework of the strip material of 50 mm.
  • the lines of the same work roll diameter (13-17) rise, for example, from below upwards in the range from 400 to 800 mm.
  • the related Thickness or stitch reduction achieved a value of 52%.
  • the set thickness reduction is, for example, 6 mm with a remaining thickness of 6 mm, corresponding to a related Height decrease of 50%.
  • the selected working point (38) is far below the maximum transferable Rolling moment in the permissible range the rolling torque line for backup roller drive (31). so that the work rolls optionally themselves (32) or driven indirectly via the support rollers (31) can be.
  • the reference numbers (43 - 47) also the same increasing work roll diameter depending on the rolling moment and decrease in thickness.
  • the desired The decrease in thickness is, for example, 3 mm with a final thickness of 3 mm, corresponding to one 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 roller drive, so that the work rolls here, as already in third scaffold, optionally own drive (42) or driven by the support rollers (41) will.
  • the reference numbers (63-67) again increasing work roll diameter in Dependence on rolling torque and thickness reduction featured.
  • the permissible working area between the lines (62) and (60) is followed by high stitch decreases right through the line of the maximum gripping angle (69) limited.
  • the numbers (73-77) denote the Lines increasing work roll diameter from 400 to 800 mm.
  • the set thickness reduction is, for example, 4 mm to achieve this a remaining thickness of 4 mm, corresponding to one related decrease in height of 50%.
  • the chosen one Working point (78) is 900 mm at 4 mm Thickness decrease far below the maximum transferable Rolling moment in the permissible range the rolling torque line for backup roller drive (not shown) and work roll drive (72).
