Definitions

  • the invention relates to a method for hiring at least one roller segment of a strand guiding device of a slab plant to a strand and a strand guiding device for performing this method.
  • EP 1 475 169 A1 is a support roll stand for continuous casting with roll segments known.
  • the roller segments each consist of a subframe and an upper frame, which are individually adjustable by means of pairs of piston-cylinder units.
  • the piston-cylinder units associated sensors, position sensor, pressure transducer, control valve blocks and the like are connected to a remote control of the continuous casting.
  • a field bus system or a transmitting and receiving module for a bidirectional data transfer of the sensors with the control of the continuous casting is provided on the upper frame.
  • the Japanese publication JP 111 29003 discloses a method and associated apparatus for easily rolling steel bar stock of wedge-shaped section.
  • WO 99/46071 discloses a method and apparatus for employing at least one roller segment a strand guiding device to a strand, wherein the roller segment comprises an upper and a lower roller carrier, each carrying at least one roller for guiding the strand between the rollers.
  • the roller segment has in its four corner regions each have a positioning element for hiring the upper and lower roller carrier relative to each other.
  • the trained hydraulic cylinder units positioning elements are both position and pressure adjustable.
  • All four adjusting elements of the roller segment are synchronously, ie driven at the same time and the values for the jobs to be adjusted to the hydraulic cylinder units are determined by a control device independently. So it is possible that each hydraulic cylinder is basically controlled independently. For the hydraulic cylinder positions are initially given, ie they are basically position-controlled and only when the pressure in the respective hydraulic cylinders has reached or exceeded a predetermined pressure threshold is switched to a pressure-controlled operation for controlling the hydraulic cylinder.
  • the item "Auto control of beach taper and thickness during casting" by Federspiel C. et al., Millennium Steel, May 2001 discloses a continuous casting machine having a strand guide for guiding a cast strand cast in a mold.
  • the strand guide consists of a plurality of segments. Each segment has four adjusting elements in the form of hydraulic cylinders associated with it for setting a top frame of the segment with respect to a subframe of the segment. Each of the hydraulic cylinders can be controlled individually. Target position values are typically predefined for the hydraulic cylinders, which must be maintained during the casting operation, except for predetermined tolerances.
  • the hydraulic cylinders on the segments serve primarily to adjust the so-called “taper" of the cast strand, ie its thickness reduction in the casting direction in the desired manner.
  • the European patent application EP 1 504 832 A1 discloses a method and a device for the contactless measurement of the profile thickness and / or the profile shape on casting strands of a multi-line casting plant for liquid metals, in particular for steel.
  • profile thickness measurements on continuous casting plants based on laser or isotope radiation systems respectively.
  • the present invention seeks to further develop a known method for hiring a roll segment in a strand guiding device to a strand and a corresponding strand guiding device to the fact that the roll guide downstream of the strand guiding device with respect to the tasks imposed on them and with regard to their mechanical load during their operation are relieved and that the quality of the strand is improved.
  • the invention ensures in an advantageous manner that any existing wedging of the profile of the cast strand, even in the strand guide device, ie even before entering the downstream rolling stands is compensated. Ideally, it is thus ensured by the present invention that the rolling stands only one strand is supplied without wedging. The rolling stands are relieved in this way, both mechanically and in view of the task which you have previously to do to remedy any possible wedging of the strand; In addition, the quality of the strand is ultimately improved.
  • the actual profile of the strand including the heights of the right and left side edge is detected and compared to determine a corresponding deviation with a desired profile containing a predetermined same desired height (H set ) for the right and left side edge.
  • the individual adjusting elements of the roller segment are then individually controlled in accordance with the deviation so that the heights of the right and left side edge of the strand are each rolled to the predetermined same desired height.
  • a profile control for the profile, d. H. to provide the cross-section of the strand In regulating the heights on the right and left side edges of the strand is a profile control for the profile, d. H. to provide the cross-section of the strand.
  • the actual profile of the strand is detected and compared with a predetermined desired profile for the purpose of determining a profile deviation.
  • the hiring of the individual adjusting elements of the roller segment is carried out in accordance with the previously determined profile deviation for the purpose of approximation of the actual profile to the predetermined desired profile.
  • this profile approximation also includes a compensation of the heights of the right and left side edges of the strand which is absolutely necessary in the context of the present invention.
  • the measured value acquisition of the actual profile takes place at the output of the last roll segment of the strand guiding device, i. H. shortly before entering the rolling stand. Because with the regulation according to the invention, a reduction of the abovementioned control deviations is aimed at zero, it is ensured in this way that actually only one strand with equal side edges is fed to the downstream rolling stand.
  • the individual adjustment of the adjusting elements for the purpose of eliminating the wedging in the case of several roller segments of the strand guiding device can take place.
  • Each roller carrier serves to carry at least one roller for guiding the strand after leaving the casting device between the roles.
  • At least one role segment in FIG. 1 if there are three, has a plurality of Anstellelemente 121 - 124 for hiring the upper and lower roller carrier 112, 114 relative to each other; see also FIG. 2 .
  • the strand guide device 100 comprises a device 130 for driving the individual Anstellelemente the roller carrier so that the right and left side edge of the strand 200 are the same height.
  • means 130 receives either measured elevations for the right and left side edges of the strand, or data representing an actual profile, ie, an actual cross section of the strand.
  • the heights of the right and left side edge of the strand can z. B. are provided by suitable measuring devices, which, for. B. are integrated into the Anstellelemente and determine there given force or pressure conditions between the two roller carriers 112, 114 of the roller segment and infer therefrom to the heights of the right and left side edge of the strand.
  • the detection of the profile of the strand can, for. B. by a suitable optical profile detection device 140; this is preferably as in FIG. 1 shown, arranged at the end of the strand guide device 100.
  • the device 130 embodied as a regulating device is capable of receiving the received measurement data, be it the current heights of the lateral edges or the current actual profile of the strand, and respectively this data for the purpose of determining a system deviation with correspondingly predetermined desired variables, ie either a predetermined for the right and left side edge of the strand predetermined height H should or to compare with a desired profile.
  • the control device then controls the individual Anstellelemente of the roller segment in accordance with the determined control deviation so that the control deviation becomes as zero as possible. In this way it is then ensured that any wedging previously present in the transverse direction of the strand, ie in the direction of its width, is compensated before entry of the strand into a downstream roll stand.
  • FIG. 2 shows an elevational view of the roll segment typically used to implement the invention.
  • the strand 200 in the direction of material flow is guided between the rollers 116, 118 of the roller segment.
  • the roller segment in its four corner regions each having a positioning element, each of these Anstellelemente equally attacks on both roller carriers and thus causes a movement of the upper and lower roller carrier 114, 112 relative to each other.
  • Anstellelemente 121 - 124 are formed as hydraulic cylinders.
  • FIG. 2 indicated by reference numeral 150 measuring devices in the individual Anstellelementen, which serve to detect the above-mentioned force or pressure conditions between the roller carriers 112, 114 of the roller segment.
  • FIG. 3 shows a cross section of the FIG. 2 known role segment, again with the same elements are designated by the same reference numerals. Especially good are in FIG. 3 to detect the significant heights Hr and HI the right and left side edge of the strand 200 for the invention. Furthermore, in FIG. 3 to recognize that the strand is not completely cured when passing through the roller segment 110, which is indicated by the still liquid part of the strand, which is denoted by the reference numeral 210. This provides for the present invention has the advantage that the applied forces to compensate for the heights Hr and HI of the right and left side edge of the strand are still relatively low, ie are less than if the strand 200 would be completely solidified.
  • FIG. 4a shows an example of a detected unwanted wedging in a strand 200, that is, that in this strand 200, the heights Hr and HI of the right and left side edges are formed unequal high. According to the invention, the detection of such a situation would trigger a control to compensate for the heights on the left and right sides of the strand.
  • FIG. 4b finally shows the same strand as FIG. 4a ,
  • the invention done balancing the heights of the right and left side edge of the strand.
