Definitions

  • Continuous casting machines with moving molds can be used to manufacture metal strips (Dr. Herrmann, "Handbook of Continuous Casting”).
  • the casting machine now produces a strip thickness which is greater than the dimension permitted for coiling or uncoiling, the casting strip must be rolled in line and in synchronism with the casting machine.
  • 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 driven roller pairs arranged one behind the other, which hold the belt emerging from the casting machine and guide under relatively light roller pressure at a speed precisely matched to the casting machine and thus keep forces acting on the belt from the outside in the casting direction away from the casting machine.
  • the mentioned additional devices result in a relatively large distance between the casting machine and the first rolling mill. As a result, the cast strip cools down on the way due to radiation and contact with guide rollers. 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 machine or of the belt driver is used as Guide section provided, which determines the speed of the other drives.
  • Guide section provided, which determines the speed of the other drives.
  • the object of the invention is now to provide a method for speed control of the drive of the casting machine and, if appropriate, the rolling mill in such a way that the previously required devices such as belt drivers, belt guides for the belt loop and continuous furnace can be omitted, which leads to considerable savings in investment and operating costs Consequence.
  • the method according to the invention is characterized in that the speed of the cast strip produced by the first rolling mill arranged after the casting machine is measured, and this speed is used as a guide value for controlling the drive speed of the casting machine. This ensures that the speed of the mold adapts and optimizes the speed of the cast strip continuously, directly, without a belt loop. If necessary, it must be ensured that the cast strip between the casting machine and the first rolling mill is tension-free over support rollers.
  • One method is that the speed of a measuring roller lying on the cast belt is processed electronically to 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 machine 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 machine 3.
  • the casting machine is shown purely schematically and can have any known structure.
  • the cast strip 4 leaving the casting machine passes a temperature measuring device 5 and a speed measuring device 6 to the roll stand 7, from which it emerges as a rolled strip 8 of reduced thickness.
  • the drive of the casting machine 3 is designated 9 and the drive of the rolling mill 10.
  • the speed of the casting machine and thus the speed of the casting strip 4 emerging from it are regulated according to the invention.
  • the speed of the cast strip 4 is also from the speed of the rolling mill and how Proceeded above, depending on other factors.
  • bas speed measuring device b now serves to record the casting belt speed between the Unu Walserk and the corresponding control of the speed of the casting machine.
  • An additional advantage is that the space required for a production line is reduced to a minimum, which in turn has a favorable effect on the investment costs.
