Thus, the valves are integrated into the bus network.
- each valve has a bus interface.
- the (typically four) valves on the roller segment may have a common bus interface, with the common bus interface being analog or digitally connected to the valves.

- the displacement measuring system is usually installed directly in the cylinder, where it is the hydraulic fluid and thus unfavorable environmental conditions (high pressures, high temperatures and chemical influences by the hot hydraulic fluid) is exposed. This increases the demands on the position measuring system regarding robustness.
- distance measuring systems typically use analogue path measuring systems or measuring systems with digital interface (SSI, Gray Code). These position measuring systems are not able to store data / information in the position measuring system (eg calibration data). Calibration data can therefore not be stored directly on the component itself, but must be made available, for example, via a database system of the common control (the so-called control system). If a segment is replaced, the calibration data must be manually assigned to the hydraulic cylinder. This is complex and can lead to problems and incorrect calibration data, since the component is not permanently connected to its calibration data. In addition, each sensor must be individually cabled and connected to the controller (axis controller), resulting in a high cabling overhead.
- controller axis controller
- pressure sensors are also used, the cabling effort continues to increase (2 pressure sensors per cylinder). Sensors with the mentioned interfaces also do not have the possibility of error detection or correction, as is possible with bus-capable sensors. Finally, prior art pressure sensors typically use analog sensors (4-20 mA, 0-20 mA, 0-10 V).
- the wiring effort increases as previously mentioned. With the increased number of terminal points and the susceptibility to errors increases by mechanical release of the compound or corrosion. As the length of the wiring increases, so does the spread for any sources of electromagnetic interference that can adversely affect transmission.
- the distance measuring system 8 is easily accessible outside the cylinder chamber of the hydraulic cylinder 3 (and thus also outside the hot hydraulic fluid) installed. As a result, the displacement measuring system 8 need only be very robust; It is also easily accessible.
- the displacement measuring system 8 with an integrated non-volatile memory (eg for calibration data) and a bus interface 9 is bus-capable and can transmit data bidirectionally via a bus (eg CAN or professional bus).
- the hydraulic cylinder 3 has two pressure sensors 22 with a bus interface 9, so that the pressure signals for both chamber pressures of the hydraulic cylinder 3 (and thus the force ratios) can be transmitted to the axis controller 10 with minimal cabling.
- FIG. 3 shows a variant of FIG. 7. Since the pressure sensors 22 of FIG.
- bus-capable position measuring systems 8 of the hydraulic cylinder 3 have two analog inputs, conventional pressure sensors 22 with an analog interface can be connected to the bus-capable position measuring system 8 and the signals for position and chamber pressures can be transmitted via the bus. This cheap analogue pressure transducer can be used, while still the cabling and the Einstreuumble be minimized. Since the hydraulic cylinder typically applies a relatively high clamping force during operation, the displacement measuring system 8 can also have only one analog input. Also In this case, the axis controller 10, a printing or
- FIG. 8 shows a first variant of the control and / or regulating device according to the invention for a support roll stand of a continuous casting machine.
- the support roller frame comprises several successive roller segments 3.

- each hydraulic cylinder 7a... 7d has a position transmitter 8a... 8d with a bus interface 9a... 9d (here a CAN interface).
- the continuous casting machine 1 itself has a common control 13 in the form of a PC. All axis controllers 10 (only a single one is shown in FIG. 8 for reasons of clarity, but see FIGS. 1-2) of the roller segments 3 are connected to the common controller 13 via a star-shaped LAN network. Specifically, the axis controllers 10 and the common controller 13 are connected to a router or switch 27 via network cables 31, respectively.
- the bus networks for the roller segments 3 are separated from each other.
- the common control 13 in turn forms a separate LAN network 21 with the axis controllers 10.
- An advantage of the star-shaped LAN network is that a failure of a network cable 31 between an axis controller 10 and the common controller 13 affects only a single role segment; the other segments continue working undisturbed. Even in this case, however, the affected segment can continue to operate emergency, as only communication between the common control 13 and the axis controller 10, but not the communication from the axis controller 10 with the position encoders 8a ... 8d, is concerned.
- FIG. 9 shows a second variant of the control and / or regulating device according to the invention. In contrast to FIG. 8, in addition to the axis controller 10 and the position sensors 8a... 8d of the hydraulic cylinders 7a...
- the hydraulic valves 16a... 16d are part of the bus network 20.
- the connection of all axis controllers 10 to the common control 13 is carried out as in Fig 8 by a star-shaped network 21.
- Each roller segment 3 is also assigned a separate valve stand 17 on the technological support structure 11 of the continuous casting machine 1.
- the valves of the separate valve 17 are also controlled by the axis controller 10 via the bus network 20.
- the separate valve 17 switches the pump pressure P of a hydraulic supply, not shown, usually in a supply room within the techn. Supporting structure 11 or Kel-1er, located to the valves 16a ... l6d on the roller segment 3 by. Before a segment change, the valve state 17 is de-energized, so that the valves 16a ...

- the valves 16a... 16d on the roller segment 3 and the valves 17 on the separate valve stand 17 are connected analogously to the separate axle regulator 10.
- the bus cable 30, shown here thickly, which connects the position sensors 8a... 8d to the axis controller 10, is detachably connected to the separate axis controller 10 by the connector 40.
- the analog input 35 would be a digital input.
- Other electrical connections, e.g. for electrical supply, can be connected via the connector 40.
- the procedure is as follows: First, the bus network 20 between the separate axis controller 10, which is assigned to the roller segment 3, and the roller segment 3 and the hydraulic connections between the valve stand 17 and the roller segment 3 is separated. Most conveniently, this is done by unplugging a single connector 40 (see FIG. 10). Subsequently, the roller segment 3 is removed from the support roller frame 2 of the continuous casting machine 1. This is usually done by a crane, which extends the roller segment 3 on rails 115 (see Fig 1-2) from the support roller frame 2. The extended roll segment is typically repaired next to the continuous casting machine 1 again. An already repaired roller segment is referred to as a new roller segment 3 '.
- Calibration data each outputs a manipulated variable signal to a valve 16 on the new roller segment 3 ', so that the actual position of a position sensor 16a ... l6d of the hydraulic cylinder 7a ... 7d corresponds to the desired position as closely as possible.
- the invention has been further illustrated and described in detail by the preferred embodiments of slab continuous casting machines, the invention is not limited to the examples disclosed, and other variations can be derived therefrom by those skilled in the art without departing from the scope of the invention.
- the invention can also be applied to continuous casting machines for long products, eg billet, billet or Vorprofilstrfiten.
- the invention also simplifies cabling for continuous casting machines for long products and reduces the time needed to replace a segment of the strand guide. LIST OF REFERENCE NUMBERS
