Definitions

  • the invention relates to a continuous casting method according to the preamble of claim 1.
  • Slabs are the starting material for the production of sheets and strips. If slabs with a thickness of> 100 mm are produced in continuous casting plants, segregation problems arise. According to DE-OS 24 44 443, the problem is to be solved in that a deformation is exerted with a degree of reduction of 0.1 to 2% on the strand within the solidification section, as shortly as possible before the solidification point, within the continuous casting installation.
  • the invention is based on the object of specifying a method with which a product with a high proportion ( ⁇ 80%) of roll structure is already made available with the continuous casting installation and which is capable of being coiled with the thickness dimension leaving the casting installation.
  • the invention is based on a continuous casting process for the production of slabs with a reduced thickness compared to the cast state.
  • Steel is poured into a continuous mold and a strand that has partially solidified in cross-section is drawn off from it.
  • the strand is guided between pairs of rollers. Some pairs of roles can be combined into segments.
  • Some of the rollers can be driven for the strand transport of the strand.
  • the rollers or the segments can be hydraulically adjusted against the strand.
  • the rollers or some of the rollers or roller segments, both within the solidification section and in the area of the solidified strand, have a deforming effect on the strand.
  • the degree of deformation is either adjustable via the hydraulic pressure of the adjusting device or limited by stops (spacers) on the rollers.
  • each adjustable, driven roller is now assigned a controller which detects the speed and the contact pressure of the rollers and the current consumption of the roller drives and controls them according to predetermined setpoints; Furthermore, each controller is connected to a higher-level controller, the position of the bottom of the sump (end of the solidification section) being known as the actual value.
  • This controller adjusts the individually adjustable roller pairs and the strand speed in such a way that the bottom of the sump lies in or just before a pair of rollers, which can be adjusted against its stops against stops and thus the final dimension and the pull-off speed of the strand, as well as the degree of deformation in the solidified state Area.
  • the location of the sump tip can be determined by the different speeds, the current consumption of the drives two Adjacent pairs of rollers and the reaction forces of the strand can be found, since the speed of the strand changes between the solidification section and the solidified area during strand deformation.
  • the reaction force of the strand can be determined from the differences between the deformation force - for example by measuring the pressure of the hydraulic medium or via pressure transducers on the roller journal - and the deformation work performed (adjustment of the rollers).
  • the superordinate controller also receives information about the steel temperature, quality, take-off speed of the strand and the position of the rollers from the machine data of the continuous casting installation due to the freely occurring stick removal in the respective roller pairs. This data is also incorporated into the setpoints of the individual controllers.
  • the speed of each roller was increased or decreased until the current consumption of all drives is the same. This is achieved by the higher-level controller, which forms the average current value from the sum of the motor currents of the individual drives. Deviations in the motor currents of the drives from the mean value are compensated for by correcting the speed setpoint of each controller.
  • the speed of the rolls can be checked and corrected on the basis of an average value which is formed from the speed of a first and third roll of Triplets combined, driven, immediately successive roles, the speed of the middle role corresponding to this mean within a tolerance range that is not greater than the difference in speed of the first and third roles.
  • Liquid steel is poured into a mold 1 with a thickness of approx. 60 mm (distance of the broad sides of the mold from one another).
  • the mold 1 is followed by rollers 2 for supporting the still thin strand shell of the partially solidified strand 3.
  • the rollers 2 are followed by a section in which the rollers are combined to form a segment 4.
  • Individual rollers 5 of the segment 4 are driven.
  • the rollers 5 can be adjusted against each other individually or as a segment by means of hydraulic cylinders 6. Even under the resulting deformation of the strand, the sump tip is held in the area of segment 4 by influencing the speed of the rollers.
  • This section of the roller guide (segment 4) is followed by a section 7 in which rollers 8 are driven and can be adjusted against one another to a certain extent against stops, not shown, in order to achieve a certain reduction in the thickness of the strand and a certain final thickness of the strand.
  • the speeds of the rollers change in accordance with the embroidery acceptance carried out between the individual pairs of rollers. Since the rollers are only spaced to the final dimension of approx. 20 to 15 mm, the speed must be able to be varied over a wide range.
  • the speeds of the individual rollers are determined and set from the current consumption of the drives of the respective roller, the hydraulic pressure and the distance between the rollers.
  • the strand 3 emerging from the mold reaches a first pair of rollers 9, 9 '.
  • the roller 9 can be adjusted by means of a hydraulic cylinder 11.
  • a roller 10 is assigned to the roller 9, which detects the pressure of the hydraulic medium and compares it with a predetermined target value and adjusts the contact pressure of the roller 9 to the strand 3 in accordance with a target value 1. From the role 9 ' Speed determined and fed to a controller 10 ', which controls the speed according to a setpoint.
  • a deformation of the strand 3 can be controlled via the contact pressure of the roller 9. After a first slight deformation, the strand 3 reaches a next pair of rollers 12, 12 '.
  • This pair of rollers 12, 12 ' has according to the pair of rollers 9, 9' on adjusting means 11 and their own controller 13, 13 '.
  • the pairs of rollers 9, 9 'and 12, 12' are in the area of the solidification section, ie before the solidification point (sump tip) 14, so that the rollers 9, 9 'and 12, 12' are operated at the same speed.
  • the deformation takes place in the solidified part of the strand 3.
  • the deformation work performed is determined via a displacement transducer 16 and fed to the controller 17.
  • the deformation work is also controlled here via the contact pressure of the hydraulic cylinder 11.
  • the deformation that occurred in the solidified area of the strand 3 is noticeable in an extension of the strand and thus an increase in the strand speed in the further pair of rollers 18, 18 '.
  • the final thickness of the strand 3 leaving the system is determined at the same time.
  • the final thickness can be done both with the help of the hydraulic cylinder 11 and a controller 19 and by spacers, not shown, which define the distance of the rollers 18, 18 'from each other.
  • a controller 19 ' provides the necessary speed of the pair of rollers 18, 18'.
  • All controllers 10, 10 ', 13, 13', 17 and 19, 19 ' are connected to a higher-level controller 20. All relevant data of the respective casting, such as steel analysis, steel temperature and casting speed, as well as the data recorded via the individual controllers, such as contact pressure of the rolls, speed of the rolls and current consumption of the roll drives, are recorded in the controller 20 and returned to the respective individual controllers as setpoints.
  • the the Specified target values for individual controllers can be modified in such a way that with a given final thickness of the strand, the deformation work is distributed as evenly as possible with the least possible load on the individual rollers, and the higher-level controller adjusts the speeds depending on the degree of deformation and the size of the solidified area and deformation in the area of the solidification section. It is possible to keep the bottom of the sump in a certain area of the system depending on the final thickness and the starting dimension of the strand. This makes it possible to produce a strand that has a high degree of roll structure.
  • the specified regulation also makes it possible to divide the deformation work within the guide path in which the rollers can be set against stops and extend over a solidified area of the strand.
  • the final dimension of the strand can already be achieved with a first pair of rollers. Roller pairs following in the strand withdrawal direction are then regulated in the sense of an agreement of the rotational speed with this roller pair determining the final dimension, that is to say kept constant. If, due to an increased resistance to deformation of the strand, e.g.
  • Figure 3 shows a schematic diagram for the control device according to claim 5, which has the advantage that slipping of a driven roller on the strand is avoided and the roller is kept in its intended use by the control loop.
  • the system is also able to compensate for deviations in the roll diameter and to automatically adjust to a new nominal speed.
  • rollers n, n + 1, n + 2 of a group of three are each driven by motors M, the speed being determined by the tachometer TD.
  • a role that is not in contact with the slab, that is to say has slip can run into the limit speed.
  • a slipping roll can on the one hand cause surface damage, and on the other hand it is possible that the re-engaging roll briefly accelerates the strand so that the strand is torn from the mold.
  • the middle roll can assume the speed of the first or last roll depending on the degree of deformation. The speed can never, given contact with the slab, be faster than the last roll of the triple and never slower than the first roll of the triple.
  • a blocking role will run into the current limit and will be reported as faulty.
  • the slipping roll is not recognized by the individual controller as involved in the transport, but if the speed of the middle roll is greater than that of the last roll of the group of three, it can only have lost contact with the slab, it has slippage.
  • a slipping role which is recognized by the speed comparison, can therefore be reported as faulty, it can also be reduced to the average speed of the group of three by intervening in the controller, so that, when contact is restored, can take part in the transport again.
  • the rollers are adjusted or the roller spacing is adjusted using hydraulic cylinders.
  • the necessary pressure is generated in a pressure-controlled hydraulic station.
  • the maximum pressure is only determined by the strength of the mechanical part of the system.
  • a path measurement must be installed on each hydraulic cylinder. Only with the help of distance measurements can jamming of the employment and other errors be recognized.
  • the adjustment is controlled by servo valves.
  • the distance measurement serves as an actual value transmitter.
  • each driven roller is driven by a controller acting as a speed controller.
  • the higher-level controller assigned to several roles has the task of compensating for minor disturbances.
  • the mean value is formed from the sum of the motor currents of each drive.
  • the deviation of the motor current of each roll from the mean value is applied to the setpoint as a correction variable.
  • the correction controller has to calculate a considerably larger correction range.
  • each run is recalculated based on the last correction value. Since the correction of the speed can be very large depending on the difference between the individual current and the mean current value, the motor can go into the limit speed when the roll is slipping (not in contact with the line). These slipping roles are then recognized by the monitoring.
