Definitions

  • the invention relates to a finishing train for continuous casting Tape material to prevent the reduction in tape thickness at the band edges occurring band material cracks this upstream Compression scaffolding, its adjusting device, position control loops are upstream.
  • the invention further relates to a method to operate the edger and finishing train.
  • the invention is based on the task, an arrangement and a Process for operating the upset upstream of the finishing train to create, on the one hand, an acquisition and introduction of the Secure the opening strip in the first scaffolding of the finishing train and on the other hand sufficient deformation of the band edge areas under all circumstances achieve which the required structural transformation to back up. Furthermore, the tape should also run in properly if disturbance factors occur, as well as overloads are secured of the upstream edger, from its adjusting devices and its drive motors must be prevented should.
  • the invention is explained in more detail with reference to a drawing.
  • a compression frame 1 in which the continuously cast Volume 2 can be compressed in its edge areas.
  • the Compression stand 1 has two caliber rolls 3, 4, which are connected by adjusting cylinders 5, 6 can be positioned.
  • the pitch cylinders 5, 6 are Position actual value transmitter 7, 8 and pressure actual value transmitter 9, 10 assigned.
  • the actual position sensors 7, 8 deliver the actual position values for position control loops 11, 12, whose outputs 13, 14 on valves 15, 16 act, which pressurizing the adjusting cylinder 5, 6 control.
  • the position specification for the gap width i.e. the position setpoints for the position control loops 11, 12 takes place via a model calculation in the computer 18.
  • a Manual additional adjustment can be specified.
  • the computer 18 from the material-specific values of the material to be rolled, the planned acceptance in the first scaffolding of the finishing train, the casting range and / or the finished bandwidth in connection with the Returning a position setpoint determined, which the position control loops 11, 12 is activated.
  • the expected compressive force is compared to the actual one via the pressure actual value transmitter 9, 10 determined total compressive force compared. If there are deviations here, the position control loops 11, 12 of the adjusting cylinders 5, 6 with the correspondingly calculated Position correction value as long as an adjustment of the Actual force is applied to the expected force until the differences are balanced.
  • controllers that have a predefinable dead band. Only when the force deviations the specifiable maximum or minimum values of this dead band exceeding / falling below is affected on the position control loops.
  • the overload limitation controller receives 20 maximum current values specified in the course of a dead band, so that the overload limitation only after exceeding the specified pressure or current values begins to work.
  • the pressure values measured by the actual pressure sensors 9, 10 are subtracted from each other to obtain a differential compressive force. If a differential compressive force occurs, this is an indication that that one of the caliber rollers 3 or 4 is loaded more than that other. Since the caliber rolls 3, 4 work against each other, is in usually the pressure at the actual pressure sensor 9 is the same as that Pressure on the actual pressure sensor 10. If there are any differences, so this can only be done by the one in a laterally fixed Guide device and on the other hand clamped in the finishing train Volume 2 have been effected. If the tape 2 runs e.g. saber-shaped into the compression frame 1, one of the caliber rollers 3 or 4 more stressed.
  • the differential compressive force becomes a differential load monitoring circuit 21 activated, which if exceeded specifiable differential compressive forces in the sense of a reduction in Differential compression force, the position control loops 11 and 12 such controls that the positioning cylinders in the same direction and by the same Amounts in the sense of a gap shift are applied.
