Definitions
- n N denotes a rated speed and I N denotes a rated current of the drive. Due to the simple relationship and the variables contained therein for calculating the additional speed setpoint, the additional speed setpoint can be determined in real time and the control device can set an additional speed setpoint determined for a specific drive.
- a nominal rotational speed of the drive, which is acted upon by a nominal current, is a characteristic of a drive, which in this way of determining the rotational speed additional value is a basis for determining the rotational speed additional value.
- the arranged above the strand 2 leading roller 4 is pressed with a pressing force A on the foundry. This ensures contact with the strand.
- the drive 8 of the roller 4, 6, 7 of this first reduction stand 13-0 is not controlled like the drives 8 of the rolling rollers 5.
- the drive 8 of this leading role 4 of the first reduction stand 13-0 is a Load setpoint given to set a desired casting speed v.
- This desired casting speed v can, for example, be supplied to the control device 10 on the user side, which then controls the drive 8 of the speed setting roller 6 of the reduction stand 13-0 accordingly.
- a method step 101 it is first determined in a method step 101 which roles are to be used as rolling rollers i or can be used due to a defect.
- the controller adjusts a rolling force F 1 for the respective i-th rolling roller in a method step 102, wherein the respective rolling force F 1 is dynamically predetermined by the above-mentioned model.
- the rolling force F 1 is detected, the actual value of the rolling force of the ith roller in a step 103.
- the detection and adjustment of the rolling force F 1 can be done substantially simultaneously.
