Definitions
- the invention relates to a control and / or regulating device for a continuous casting mold carrying a lifting table of a continuous casting machine for liquid metals, in particular for liquid steel material, with an oscillating drive, the up and down movements on the lifting table and the continuous casting transfers, by means of several stationary and on Lifting table hinged piston-cylinder units are generated, with field measuring devices attached to the hydraulic cylinder, a valve block with a control valve and a plurality of pressure transducers and integrated in the hydraulic cylinder, a position sensor and the signals of the field measuring devices via electrical connections to the control and / or control station routed and routed back to the associated actuators.
- An oscillating drive for a continuous casting mold on a lifting table is known, for example, from DE-A1-198 45 357. Oscillation forces are measured for a basic setting of amplitude and frequency. Quadratic, double-acting independent hydraulic cylinders are metrologically recorded and the measurement data used to diagnose the casting machine and / or the casting process.
- the field measurement devices valve block, control valves, pressure sensor and position sensor
- the underlying central processing of the measured data is therefore a disadvantage of such controls.
- the invention has for its object to propose a control or regulation of the decentralized type, in which, taking into account the large distances to the control station and despite the high number of signal lines, a lower cabling effort is required.
- the object is achieved in the above-mentioned control and / or regulating device according to the invention that the electrical connections are performed in the vicinity of the lifting table as a cable package each to an axis controller, via a field bus with a remote in the control and / or Regulating state lying programmable logic controller is connected.
- the cabling effort is significantly reduced by the short distance between the field devices and the axis controller.
- the application software in the axis controllers can be standardized.
- the transfer of data between the programmable controller and the axis controller is time-critical and safe.
- the axis controllers are of particular importance.
- Axis controllers are special microprocessor-based circuits used to control servo axes.
- the standard software in motion control adds a real-time control for axis adjustment.
- the motion control has u. a. Interfaces for machine or step position transducers, digital or analog inputs or outputs, a Profibus and a network, for example based on Ethernet.
- the motion controller used for the application of an axis controller includes a remote control and a display device.
- the application software is standard and stored in a recallable memory.
- the motion control is able to control multiple axes (hydraulic piston-cylinder units). Based on a graphical menu, the motion control is adjusted via parameters to the axis type and to the type of position feedback. A program It is not necessary to massage.
- the motion control receives the required setpoints and the start movement via the fieldbus line connection and links these back to the higher-level system with the position and a status display. Further advantages result from the fact that the transmission of the data between the programmable logic controller and the respective axis controller is uncritical and safe over time.
- Application software modules can be standardized. Material costs and installation and time wiring costs can be reduced. The electrical susceptibility is reduced. Likewise, the maintenance is reduced. Times for installation and commissioning are reduced.
- One embodiment provides that the field measuring devices can be disconnected or reconnected from the lifting table via a plug connection. As a result, a quick removal or replacement of the continuous casting mold can be carried out advantageously.
- lifting modules are each formed with two position sensors and two control valves and four pressure transducers. As a result, only two SSI and six analog signals and a few digital signals need to be processed by the control and / or regulating device.
- the axis controllers have a special meaning. According to further features, it is provided that the axis controllers are arranged within a protective terminal box.
- the axis controllers are used for signal processing in the hydraulic circuit of the lifting table, the continuous casting mold and the hydraulic piston-cylinder units for detecting, transmitting, processing and outputting the signals. Further advantages result from the fact that the axis controller is connected with a cable for the power supply, with a cable for the power supply of a fieldbus module and with a cable for the data of the fieldbus module.
- the axis controller with standard software in the motion control for the axis adjustment of the hydraulic cylinder with interfaces for absolute or Incremental position encoder, digital or analog on or Outputs, the fieldbus and in a network.
- Fig. 1 is a side view of any continuous casting machine with hall frame
- Fig. 2 is a vertical section through a lifting table with continuous casting mold
- Fig. 3 is a simplified representation of a block diagram of the supported on several hydraulic piston-cylinder units lifting table.
- the continuous casting machine 1 - Fig. 1 - is operated from a ladle 2 with liquid steel material 3, which is cooled from the ladle 2 in a distribution vessel 4 and further by a continuous casting mold 5, in the edge region with a strand shell, while a steam chamber 6 passes and is guided and moved in the increasingly solid state by means of support roller pairs 7.
- Support roller pairs 7 form support roller segments 8.
- the inside partially still liquid and externally solidified cast strand 9 continues to cool and is bent back during cooling or solidification in the horizontal direction, ie directed.
- the continuous casting mold 5 - FIG. 2 - is mounted on a lifting table 10 of the continuous casting machine 1.
- the lifting table 10 is provided with an oscillating drive 11 of at least two, in the embodiment of four piston-cylinder units 12 together with leaf spring pairs 13.
- the piston-cylinder units 12 are fixed in each case with the hydraulic cylinder 12a, articulated in the embodiment of the upper transverse legs 14 and connected to the piston head 12b via additional lower transverse legs 14 with the lifting table 10.
- the upper transverse legs 14 form a rigid structural unit with U-legs 15a with a U-shaped support frame 15.
- field measuring devices 16 consist of a valve block 17, with a control valve 18 and pressure transducers 19 and from a position sensor 20 integrated in the hydraulic cylinder 12a.
- the electrical connections 21 for the field measuring devices 16 consist of the signals leading BUS lines 22, wherein the signals of the field measurement devices 16 in cable packages 23, provided with connectors 24 to a control and / or control station 25 - Fig. 1 - passed and after processing the signals in the associated actuators, eg. A valve 26, are returned.
- control and / or regulating station 25 Other signal lines 27 of the support roller segments 8 and / or the continuous casting mold 5 are connected via a terminal box 28 in the control and / or regulating station 25.
- the control and / or regulating station 25 is arranged on a protected, but from there clearly arranged area of a hall scaffold 29.
- the electrical connections 21 are connected in the vicinity 30 of the lifting table 10 in the cable packages 23 each to an axis controller 31, which is provided via the BUS lines 22 of a fieldbus with a programmable controller 32 provided in the control and / or regulating station 25. 3 - communicates.
- the field measuring devices 16 are each connected via the plug connection 24 - Fig. 3 - with the lifting table 10 and can be easily disconnected, disconnected or reconnected.
