Definitions
- the invention relates to a method for regulating the width of the mouth on segments for continuous casting plants, in particular on position-controlled segments for slab and thin slab continuous casting plants, comprising a strand guide with segments for the intended guidance of a cast strand using measurement and control signals.
- the invention also relates to an apparatus for performing the method.
- the state of the art includes position and pressure-controlled segments (segment cylinders) in continuous casting plants.
- segments are set up in the jaw width via hydraulic cylinders and assignable measuring / regulating and control elements.
- control and control elements required for this are located in remote switching devices of the continuous casting plants.
- Document DE 100 28 304 A1 discloses a method and a device for decentralized casting data processing of the measurement data obtained on sensors in a continuous casting mold in a process computer of a continuous casting plant.
- This known development is based on the task of electronically processing, among other things, the casting data measured by sensors in a more efficient way, and thereby also simplifying the devices provided for this purpose.
- the measurement and control data are cooled Fieldbus modules are collected directly on the continuous casting mold and converted into bus signals in a bus line and at least stored and / or processed in the control of the continuous casting system. This significantly shortens and simplifies the data path and also simplifies the setup.
- mold-specific information e.g. B. on the thickness of the copper plates, the degree of wear, the state of the thermal sensors and / or the resistance thermal sensors and the maintenance cycles are stored.
- the document WO 99/46071 discloses an adjustment method for a roller segment of a continuous caster, which has a segment entrance side, a segment exit side and a pair of roller carriers, each of which carries at least two rollers extending over a support area.
- the roller carriers are set against each other via a positioning unit arranged on the segment entrance side and on the segment exit side.
- Each adjusting unit has two hydraulic cylinder units arranged on both sides of the support area.
- the adjustment method known from this consists in that the hydraulic cylinder units can be adjusted both in a position-controlled and pressure-controlled manner, that the rollers are adjusted in a position-controlled manner on a metal strand guided by the rollers, and that the hydraulic cylinder units are switched over from position-controlled to pressure-controlled operation when the pressure in the respective hydraulic cylinder unit reaches a limit value.
- the object of the invention is a decentralized control and regulation with corresponding modules directly on a segment or directly on a hydraulic cylinder to be installed in order to create an "intelligent segment" which ensures further operation even in the event of communication data failure.
- measurement and control signals are processed in at least one system unit directly on the respective segment and the setpoint values are transmitted by a higher-level control system via a fieldbus, eg. B. Profibus, are fed to the segment and (STvalue data are also returned to the control system as a control result or as a process state via the fieldbus.
- a fieldbus eg. B. Profibus
- STvalue data are also returned to the control system as a control result or as a process state via the fieldbus.
- the system units located on the segment are segment-specific information such as stiffness coefficients, roller diameter, controller parameters, Basic width settings and employment rates supplied.
- the decentralized system unit in addition to the task (s) required for segment operation further decentralized segment-specific tasks such as acquisition and processing of further measurement data, eg. B. Bearing force monitoring, temperature measurements and controls, calibration data can be assigned.
- the segment is enabled, even if the communication to the control system fails, the data set or stored in the control module, for. B. for the TARGET position or the set TARGET force value independently.
- the battery unit required to bridge the communication failure is also located on the segment.
- each segment has at least one decentralized system unit which is designed with at least one position and pressure sensor and is preferably connected to a higher-level control system and a voltage supply via a fieldbus or Profibus.
- strand guide 1 shows a construction of a strand guide 1 known per se, comprising a number of strand guide segments 2, which, with increasing solidification, guide the strand 3, emerging from the mold, safely through the areas of soft reduction or liquid core reduction.
- the segments 2 (shown enlarged) are provided with hydraulic adjusting devices, which in turn are equipped with a position transmitter 7 and preferably a pressure transmitter 8. These are position- and pressure-controlled segments 2, which are adjusted by means of hydraulic cylinders and assigned measuring / regulating and control elements in the jaw width and in the position according to predefined target values.
- the existing regulation and control technology is located in remote facilities or switching stations 4 of the continuous casting plant.
- each segment 2 has an autonomous, decentralized controller 14, which has at least one independent position and pressure transmitter 7, 8 and is preferably connected via a bus connection 11 or a Profibus to a higher-level control system 10 and a voltage supply 12.
- the existing lines with plug connections 13 require only a fraction of the line system 5 with plug connections 6 in the state of the art according to FIG does not collapse on the segments.
- so-called intelligent terminals can be provided as an advantageous alternative solution.
