Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • a mold is understood to be any element used to form a casting space, such as circumferential metal strips, successive blocks consisting of one piece or of several composite details, and also so-called casting wheels.
  • the casting device now produces a strip thickness which is greater than the dimension permissible for coiling or uncoiling, the casting strip must be rolled in line and in synchronism with the casting device.
  • the speed of the rolling stock can fluctuate as a function of time by several%, even if the peripheral speed or the speed of the rolls remains constant.
  • the belt driver consists of one or more pairs of driven rollers arranged one behind the other, which grip the belt emerging from the casting device and guide it under relatively light roller pressure at a speed which is precisely matched to the casting device and thus keep forces acting on the belt from the outside in the casting direction away from the casting device.
  • the mentioned additional devices result in a relatively large distance between the casting device and the first rolling mill.
  • the result of this is that the cast strip cools down as a result of radiation and contact with guide rollers.
  • a continuous furnace In order to achieve the required rolling temperature, a continuous furnace must usually be provided in front of the rolling mill to compensate for the heat losses.
  • the drive of the casting device or of the belt driver is provided as a guiding section which determines the speed of the other drives.
  • the drive of the casting device or of the belt driver is provided as a guiding section which determines the speed of the other drives.
  • a method for speed control of a casting device is also known, the speed of the moving molds of the casting device being regulated as a function of the detected speed of the cast strand.
  • the casting device is used to produce a strand of considerable thickness, which runs through an arc below the oscillating mold and then emerges horizontally from the casting device through a straightening unit.
  • a rolling mill is not mentioned, and it is therefore not recognizable that there could be a connection between the influence of the rolling mill on the strand speed and the detection of the strand speed. Rather, it can be assumed that the casting device is not followed by a rolling mill, but the strand is cut into billets without changing the cross-section.
  • One method is that the speed of a measuring roller resting on the casting belt is electronically processed into a control signal in a known manner. It is also possible to use contactless measuring and control devices on the market. ("Swiss machine market", No. 18/1974, pages 42/43).
  • the belt speed is preferably measured at the outlet of the casting device and used as a guide value for controlling the drive.
  • the drawing shows the casting trough 1 and the casting trough 2 from which the molten metal is fed to the casting device 3.
  • the casting device is shown purely schematically and can have any known structure.
  • the casting belt 4 leaving the casting device passes a temperature measuring device 5 and a speed measuring device 6 to the rolling stand 7, from which it emerges as a rolling belt 8 of reduced thickness.
  • the drive of the casting device 3 is designated 9 and the drive of the rolling mill 10.
  • the speed of the casting device and thus the speed of the cast strip 4 emerging from it are regulated according to the invention.
  • the speed of the cast belt 4 is also dependent on the speed of the rolling mill and, as mentioned above, on other factors.
  • the speed measuring device 6 is now used to record the speed of the casting belt between the casting device and the rolling mill and to regulate the speed of the casting device accordingly.
  • the temperature of the casting belt 4 determined by the temperature measuring device 5 at the outlet of the casting device 3 can serve to control the speed of the rolling mill 7, which speed in turn influences the speed of the casting belt 4, which is detected by the speed measuring device 6 and controls the speed of the casting device accordingly.
  • measuring and control devices include the controls 11 and 12 shown schematically in the drawing, which receive the signals from the speed measuring device 6 and the temperature measuring device 5 at the inputs A and B, respectively. As the drawing shows, the controller 11 regulates the drive 9 of the casting device. In the drawing, a cooling system is also indicated, which allows parts 13 of this system to supply cooling water to the coolers 15 of the pouring device via control valves 14.
  • the cooling water supply is regulated as a function of the temperature determined by the temperature measuring device via the controller 12, specifically in the sense that cooling is higher at a higher temperature than at a lower one.
  • the controller 12 also regulates the drive 10 for the rolling mill as a function of the temperature determined. The following options are available:
  • the belt speed is regulated by special measuring results
  • An additional advantage is that the space requirement for a production line is reduced to a minimum, which in turn has a favorable effect on the investment costs.
