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 computer program and a strand guiding device for carrying out this method.
- All four adjusting elements of the roller segment are synchronously, ie controlled at the same time, and the values for the positions to which hydraulic cylinder units are adjusted are determined independently of one another by a control device. So it is possible that each hydraulic cylinder is basically controlled independently.
- positions are initially specified, ie they are always position-controlled and only when the pressure in the respective hydraulic cylinders is predetermined Pressure point value has been reached or exceeded, is switched to a pressure-controlled operation for controlling the hydraulic cylinder.
- the present invention seeks to develop a known method for hiring a roller segment in a strand guide device to a strand to the fact that the strand guide device downstream rolling stands in view of the tasks imposed on them and with regard to their mechanical load during their operations and that the quality of the strand is improved.
- This object is achieved by the method claimed in claim 1.
- This method is characterized in that the individual Anstellelemente the role segment are individually controlled so that the heights of the right and left side edge of the strand are the same size.
- 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 elimination of the eventual wedging in the strand guiding device takes place at a position or at roller segments in which the strand has not yet solidified. This has the advantage that much lower forces must then be exerted on the strand from the rolls of the roll segments to eliminate the wedging, as if the strand were already solidified, as is usually the case when entering the downstream roll stands.
- the individual adjustment of the adjusting elements for the purpose of eliminating the wedging can take place either only in individual, in several or even in all roller segments of the strand guiding device.
- employment of the adjusting elements in several roller segments requires a technically greater effort, but has the advantage that then only smaller forces must be expended at the individual Anstellelementen; This is especially true because then a large number of Anstellelementen in several roles segments are available to compensate for the wedging in total.
- the hiring of the Anstellelemente to compensate for the wedging can be done either in the form of a controller or a scheme.
- a control only an equal desired height for the right and left side boundary of the strand is specified and the Anstellelemente on the right and left side of the roller segment (as seen in the material flow direction) are driven accordingly.
- the heights of the right and left side edges of the strand are detected and compared to determine a corresponding deviation in each case with a predetermined same nominal height 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.
- the actual profile of the strand is first detected and compared with a predetermined desired profile for the purpose of determining a profile control deviation. Also in this case, then the hiring the individual Anstellelemente of the roller segment in accordance with the previously determined profile deviation for the purpose of approximation of the actual profile to the predetermined target profile.
- this profile approximation also includes, in the context of the present invention, absolutely necessary compensation of the right and left lateral edges of the strand.
- the detection of the heights of the side edges of the strand or the detection of the actual profile of the strand can be carried out at different locations within the strand guiding device.
- the detection preferably takes place at the exit of such a roller segment, which has controllable setting elements.
- the measured value is recorded at the output of the last roll segment of the strand guiding device, d. H. shortly before entering the rolling stand. Because with each regulation according to the invention, a reduction of the above-mentioned control deviations is aimed at zero, it is then ensured in this way that actually only one strand is supplied with the same high side edges of the downstream rolling mill.
- any differences in the heights of the side edges of the cast strand are calculated on the basis of measured force and / or pressure conditions, preferably in the area of engagement of the setting elements.
- the actual profile of the strand z. B. using suitable profile detection devices z. B. be detected optically.
- the above object is further achieved by a computer program and a strand guiding device for carrying out said method solved.
- the advantages of the computer program and the strand guiding device essentially correspond to the advantages mentioned above with reference to the claimed method.
- Figure 1 shows a new strand guiding device according to the invention
- Figure 2 is an elevational view of a roller segment
- Figure 3 shows a cross section through the roller segment
- Figure 4a shows a strand with wedging in the roll segment
- 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 roller segment, in FIG. 1 it is three, has a plurality of positioning elements 121-124 for positioning the upper and lower roller carriers 112, 114 relative to each other; See also Figure 2.
- the strand guide device 100 comprises means 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.
- the device 130 may be designed either as a control device or as a control device. If it is merely designed as a control device, it gives each z. B. position values for the individual Anstell- elements before so that the right and left side edge of the strand is rolled in each case to the same height. The specification of the positions is then preferably in each case such that the right and left side edges of the strand are each rolled to an identical predetermined desired height.
- the device 130 When the device 130 is designed as a control device, it receives either measured heights 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.
- the detection of the profile of the strand can, for. B. by a suitable optical profile detection device 140; this is preferably, as shown in Figure 1, 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 control deviation with correspondingly predetermined desired variables, ie either a uniform predetermined for the right and left side edge of the strand predetermined height H SO ⁇ or with a desired profile to compare.
- the control device then controls the individual setting elements of the RoI lensegmentes in accordance with the determined control deviation so that the control deviation is as possible to zero. 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 rolling stand.
- FIG. 2 shows an elevational view of the roll segment typically used to implement the invention.
- the same elements as in Figure 1 are designated by the same reference numerals.
- 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.
- the Anstellelemente 121 - 124 shown in Figure 2 are designed as hydraulic cylinders.
- the reference numeral 150 indicates measuring devices in the individual setting elements, which are used for detecting the above-mentioned embodiment. Force or pressure conditions between the roller carriers 112, 114 serve the roller segment.
- FIG. 3 shows a cross section of the roller segment known from FIG. 2, wherein in turn identical elements are designated by the same reference numerals.
- the heights Hr and Hl of the right and left side edges of the strand 200 that are significant for the invention can be seen particularly well.
- the strand has not yet completely cured when passing through the roll segment 110, which is indicated by the still liquid part of the strand, which is designated 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 Hl 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. 4 a shows an example of a detected unwanted wedging in a strand 200, ie that in this strand 200 the heights Hr and Hl of the right and left side edges are of unequal height. According to the invention, the detection of such a situation would trigger a control or regulation to compensate for the heights on the left and right sides of the strand.
- FIG. 4b shows the same strand as FIG. 4a, but according to the invention, compensation for the heights of the right and left side edges of the strand.
