Definitions
- the invention relates to a device for hydraulic hiring of components, in particular the roles of strand guide segments of a continuous casting, with hydraulic cylinders, which are divided by a respective piston with piston rod in a cylinder chamber and a ring cylinder space, wherein the cylinder chambers are connected by control members with a pressure source.
- the invention is based on a device as known from EP 1 105 235 B1.
- Be continuous casting begins the casting process in the mold. From this emerges the superficial solidified strand and is then passed through strand guide segments to a horizontally arranged straightening driver. The leadership of the strand is done by guide rollers, which are adjustable by hydraulic cylinders against the strand.
- the object of the invention is to achieve a reduction of hydraulic connection lines, or a reduction of components used, for. B. pressure sensors to achieve.
- the loading of the piston takes place in the annular cylinder space via a einkantenschreib.es control valve.
- a pressure sensor is provided between the control valve and cylinder or there is a position sensor on the cylinder for the position control.
- the invention thus represents a novel hydraulic control concept for strand guides of continuous casting.
- Einkantenregelung for the positioning or force setting of Strand guiding elements (adjustment of the mouth widths of strand guiding elements for an LCR method, soft reduction hard reduction, thickness adjustment or the adjustment of a required setting force) are used.
- FIG. 1 schematically the valve and cylinder arrangement
- FIG. 2 schematically the regulation of the annular cylinder space
- FIG. 3 schematically the position regulation
- FIG. 4 schematically the pressure regulation.
- the cylinder chamber to be controlled - in the illustrated embodiment 5 - (rod side or piston side or rod cylinder side used in the case of synchronous cylinders) is freely determinable according to the process requirements (or safety concepts).
- a presettable fixed pressure for the annular cylinder space 4 is also to be defined according to the process requirements. In the regulation of the position of a hydraulic cylinder or the control of a cylinder force only a pressure on the control valve 6 or 7 used is varied.
- the acting on the opposite (complementary) space 4 constant (but variably adjustable pressure) generates the force required for a reset (Stellraumsan- change) of the cylinder piston 3.
- the used control valve 6 or 7 is loaded according to the invention only on a control edge. The second control edge of the control valve remains unused.
- each position transmitter 9 cooperating with the cylinder piston is provided on the cylinders. These are omitted in the pressure control of Figure 4, d. H. There pressure sensors 8 are inserted into the lines between the valves and the hydraulic cylinders.
- the constant second pressure is known as the default value and can be used to calculate the resulting total force (taking into account the effective piston area).
- the single-edge controls for position or / and pressure control can also be carried out with switching valves.
