Definitions

  • the invention relates to a device for adjusting the width of segments for continuous casters, at least with a position and pressure transducer are formed, in particular on segments for slab and thin slab continuous casting, comprising a strand guide with a control and segments for an intended guidance of a cast strand using measuring and control signals.
  • the invention also relates to the use of the device.
  • the state of the art includes position- and pressure-controlled segments (Segment cylinder) in continuous casting plants.
  • Segments via hydraulic cylinders and assignable measuring and control devices employed in the mouth.
  • SR Purpose of Softreduction
  • LCR Liquid Core Reduction
  • the necessary control and control elements are located in remote switching facilities of the continuous casting plants.
  • Document DE 100 28 304 A1 discloses a method and a device for decentralized casting data processing on a continuous casting mold Sensors obtained measurement data in a process computer of a continuous casting.
  • This known development was based on the task of electronic Way u. a. the casting data measured by sensors on more efficient Because of processing, and thereby also the facilities provided for this purpose to simplify.
  • the measuring and control data are cooled Fieldbus modules collected directly on the continuous casting mold and in bus signals transferred to a bus line and at least in the control of Continuous casting plant stored and / or processed. This will be the data path considerably shortened and simplified, and also simplifies the device.
  • thermo-sensors and / or the resistance thermosensors and the maintenance cycles are stored retrievably.
  • the document WO-99/46071-A discloses a setting method for a roll segment a continuous caster, which has a segment input side, a segment output side and a pair of roller carriers each having at least two carrying over a support area extending rollers.
  • the role carriers become via one at the segment input side and one at the segment output side arranged adjusting unit against each other employed. Every hiring unit has two on both sides of the support area arranged hydraulic cylinder units on.
  • the Anstell compiler known from this is that the hydraulic cylinder units can be adjusted both position and pressure-controlled, that via the hydraulic cylinder units, the rollers are position-controlled to one of the rollers run metal strand are hired, and that the hydraulic cylinder units be switched from position to pressure-controlled operation, when the pressure in the respective hydraulic cylinder unit is a limit reached.
  • the invention has the object underlying, a decentralized control and regulation with appropriate Modules directly on a segment or directly on a hydraulic cylinder to install, so as to create an "intelligent segment", which also secures further operation in the event of a failure of communication data.
  • each segment has at least one own decentralized control system unit, which via a field bus or Profibus with a higher-level control system and a power supply communicates.
  • the measurement and control signals in at least one system unit directly processed on the respective segment and the nominal value specifications of one higher-level control system via a fieldbus, e.g. Profibus, and a power supply fed to the segment, as well as actual value data also via the fieldbus to the control system as a control result or process state to be led back.
  • a fieldbus e.g. Profibus
  • the decentralized System unit next to the required task (s) for segment placement further decentralized, segment-specific tasks as recording and processing of other measurement data, z. B. bearing force monitoring, Temperature measurements and controls, associated with calibration data become.
  • the segment is enabled even if communication with the control system fails or stored in the rule module data z. B. for the desired position or the set SOLLkraftwert independently too active.
  • the required battery unit to bypass the communication failure is also located on the segment.
  • strand guide 1 shows a known construction of a strand guide 1, comprising a number of strand guide segments 2, which comprise the strand 3, emerging from the mold, with increasing solidification through the areas of Safely pass on soft reduction or liquid core reduction.
  • the segments 2 are with hydraulic actuators provided, in turn, with a position sensor 7 and preferably a Pressure transmitter 8 are equipped. These are position and pressure controlled Segments 2, which are controlled by hydraulic cylinders and assigned measuring / control and control organs in the mouth as well as in the position accordingly predetermined SOLLWerte be made.
  • the existing for this Control technology is located in remote facilities or switching stations 4 of the continuous casting.
  • each segment. 2 has an autonomous, decentralized controller 14, the at least one independent position and pressure transducer 7, 8 equipped and preferably via a bus connection 11 or a Profibus with a superordinate one Control system 10 and a power supply 12 is in communication.
  • the existing lines with connectors 13 require only one Fraction of the conduit system 5 with connectors 6 in the state of Technique according to FIG. 1.
  • Another serious advantage results from this that in case of failure of the transmission lines or connecting elements the regulation or control because of their self-sufficient position on the segments does not collapse.
  • the control and control units on The segment 2 can be called an intelligent Aftemativates so-called intelligent Terminals are provided.
