Definitions

  • the invention relates to a control and / or regulating device for a support roller stand of a continuous casting apparatus for metals, in particular steel materials, which consists of several successive roller segments, each controlled via the support rollers supporting subframe and an opposite upper frame by means of paired piston-cylinder units against each other can be adjusted, for conveying, straightening and / or improving the internal quality and the thickness change, the measurement data of field devices are detected and processed decentralized.
  • each roller segment has 4 position sensors, 4 sets of control valves (servo and switching valves) and in some cases eight pressure transducers / pressure transducers, four synchronous-serial interfaces and 12 analogue or digital signals must be processed per segment.
  • control valves servo and switching valves
  • eight pressure transducers / pressure transducers four synchronous-serial interfaces and 12 analogue or digital signals must be processed per segment.
  • In a continuous caster there are often more than 15 staffed roller segments: in these 60 synchronous serial interfaces and 180 analog or 240 digital signals are to be processed by a control valve. With this large number of signals to be processed, the cost of a central control circuit is too high and the central control circuit reaches its limits of performance.
  • the European patent application EP 1475 169 A1 discloses a control or regulating device for a support roll stand of a continuous casting apparatus for metals, in particular for steel materials.
  • the support roll stand consists of several successive in strand guide direction roller segments, each having a support rollers supporting sub-frame and a support rollers supporting upper frame.
  • the subframe and the opposite upper frame are adjusted by means of paired piston-cylinder units against each other regulated for conveying, straightening and / or improving the internal quality and changing the thicknesses of the metals.
  • the signals from position sensors of the hydraulic cylinder units are each guided to a terminal box and of the terminal box a cable package is guided via a detachable media coupling on a stationary hall scaffold.
  • the invention has the object to improve the field wiring and the control concept for a support roll stand a continuous casting.
  • a separate axis controller is arranged with a connected valve stand on the stationary hall frame for each roller segment and in that signals from all the axis controllers are each guided via a fieldbus module to a common programmable logic controller in a control space of the continuous casting apparatus.
  • the axis controller stores the stored signals for positioning the support rollers, synchronizing the driven support rollers of adjacent roller segments, for left or right hydraulic cylinders or for the inlet side or outlet side, monitoring the state of the sensors, a Rollensegment- Coding, for maintenance cycles u. Like. Processed.
  • terminal boxes are cooled by means of existing on the upper frame of the roller segment machine cooling water.
  • fieldbus modules can be physically connected by means of electrical metal lines, optical waveguides or wireless transmission technology or infrared signals.
  • cables of the cable package for the power supply, the axis controller and the field bus modules are connected by means of a common plug connection.
  • the cable for the signals of the position sensor is formed by the terminal box on the roller segment by means of a media coupling as a detachable plug connection to the axis controller.
  • the integrated in the hydraulic cylinders position sensor of each roller segment must be connected via the connector to the valve from the hall scaffold and from there with all other signals with the installed on-site axis controller.
  • the continuous casting apparatus 1 has a support roller frame 2, in which the flowed from liquid steel material 3 from a ladle 4 via a manifold 5 and a continuous casting mold 6 and partially cooled cast strand 7 is supported and further cooled.
  • the support roller frame 2 consists of several, often up to 15 roller segments 8, of which the first roller segment 8a is surrounded by a steam chamber 9.
  • Each of the successive roller segments 8 is formed of a support rollers 10 supporting subframe 11 and an opposite upper frame 12.
  • the subframe 11 and the upper frame 12 are each by means of paired piston-cylinder units 13, see. Fig. 2 , regulated against each other, of which in Fig. 2 two pairs with their hydraulic cylinders 13a are visible.
  • the measurement of the hydraulic pressures, positions of the pistons, etc. with the result of measurement data is by means of sensors, position sensors, pressure sensors, control valves u. Like. Get summarized under the concept of field devices 14 to understand. In addition, switching valves 15 and control valve blocks 16 are used. The thereby controlled and / or regulated piston-cylinder units 13 promote, direct and / or improve the internal quality of the casting strand 7 and take into account via the support rollers 10 local changes in thickness.
  • the field devices 14 may replace a central control system by a respective decentralized:
  • the field devices 14 are on or on the roller segment 8 or in the vicinity of the roller segment 8 on the stationary hall scaffold 17, which also as so-called. "venue” is arranged, with their measurement signals are processed and stored via axis controller 18 and the axis controllers 18 communicating with a programmable logic controller 19 and with a fieldbus module 20.
  • the type of assignment of measuring elements and assemblies according to Fig. 3 is that on the roller segment upper frame 12, the signals of the position sensor from the hydraulic cylinders 13 a are guided in each case to the terminal box 21.
  • a cable package 23 formed by means of a detachable media coupling 22 is guided by its roller segment 8 onto the stationary hall scaffold 17 or onto the continuous casting apparatus 1 and the axis controller 18.
  • a valve stand 26 is connected to the stationary stand 17.
  • the signals from the axis controller 18 are fed via the field bus module 20 to a programmable logic controller 19 in the control chamber 25 of the continuous casting apparatus 1.
  • the axis controller 18 processes the stored signals for positioning, synchronizing, for left or right hydraulic cylinders 13a or for activating the inlet or outlet side of the casting strand 7, the state of the sensors, a role segment coding, for maintenance cycles or similar functions.
  • the terminal boxes 21 on the upper frame 12 of a roller segment 8 are cooled with the machine cooling water otherwise available there.
  • the field bus modules 20 are physically connected and connected by means of electrical metal lines, or optical fibers or wireless transmission technology or infrared signals.
  • the cables of the cable package 23 for the power supply transport the energy for the axis controller 18 and the field bus modules 20 and form a common connector 22 a.
