Definitions
- the invention relates to a continuous casting plant with a device for determining solidification states of a cast strand and a method for this.
- Continuous casting plants are well known in the art. Such continuous casting plants for casting liquid metal have, after the mold, typically a support roll stand with strand guide segments for the cast strand.
- the knowledge of the solidification length of the cast strand is of particular importance.
- the solidification length or the point of complete solidification of the strand is a parameter for operating the continuous casting plant.
- the point of solidification or the solidification length corresponds to a point with a fixed portion of the cast strand of 100%, which means that in the core of the casting strand no liquid or doughy material is no longer present.
- the knowledge about the degree of solidification of the strand is less than 100% of interest for strand guidance and strand cooling.
- Continuous casting plants are known in the prior art in which the solidification length is achieved by measuring the displaceable amount of the core liquid volume per unit length and building on these measured values Model calculation is performed for the instantaneous length of the sump tip.
- Such a continuous casting plant is known from WO 2005/068109 A1.
- EP 1 193 007 A1 discloses a method for determining the position of the final solidification in the casting strand, wherein support segments are provided and for determining the position of the final solidification at least in one of the support segments, the pullout pull-out force of the tension rollers and / or the locking force of the hydraulic piston-cylinder Units of the support segments is measured and determined from the measurements of the area of the sump tip.
- the object is achieved with respect to the continuous casting, by the features of claim 1 with a continuous casting with a device for determining solidification states of the casting strand with a strand guide with Strangg screenssegmenten with roles, in which at least
- one of the Strangg cashsegmente is designed as a measuring segment, wherein at least one or more measuring points for direct or indirect determination of the force acting on one or more rollers is provided, further arranged the at least one measuring point on a bearing block preferably between a bearing and the segment frame of the continuous casting segment is 0 and a data processing unit is provided which determines the solidification states of the cast strand based on the data of the at least one measuring point.
- the at least one measuring point is provided on at least one bearing block of a center bearing or several center bearings. As a result, the force acting on the roller through the cast strand force can be reliably detected.
- the measuring point is provided on a bearing block on the fixed side and / or on the loose side of a roller. As a result, an uneven force distribution on a roll can advantageously be detected.
- connection may be useful via a data line or data lines or cable. be made bellos. Also, the connection can be made via the data processing unit. It is expedient if the connection is made by the data processing unit to a measuring system or several measuring systems.
- center bearings of single or multiple split rollers are designed as measuring points or provided with measuring points.
- a determination of a solidification state can be carried out by assigning a solidification state to a characteristic measured variable.
- a characteristic parameter is the bearing deformation or the deformation of a bearing element, such as a slot of the bearing.
- a determination of the solidification state can be carried out by assigning a solidification state to a scattering of a characteristic measured variable.
- a scattering of a characteristic measured variable is the scattering of a bearing deformation or the scattering of the deformation of a bearing element.
- a measured variable can be evaluated by the data processing unit by means of fast Fourier analysis or other statistical evaluation methods, and thus instrumental influences on the measured variable can be determined.
- the object with regard to the method is achieved with the features of claim 13 with a method for determining solidification states of a cast strand in continuous casting plants with a strand guide with continuous casting segments with rollers, in which at least one of the continuous casting segments is designed as a measuring segment, wherein at least one measuring point or more Furthermore, the at least one measuring point is preferably arranged on a bearing block between a bearing and the segment frame of the continuous casting segment which detects a variable representing a force and a data processing unit is provided which determines the solidification states of the casting strand on the basis of the data of the at least one measuring point.
- the measuring point is provided on at least one bearing block of a center bearing or more central bearings. It is also expedient if the measuring point is provided on a bearing block on the fixed side and / or on the loose side of a roller. Also advantageously, a plurality of measuring points are provided within the strand guide, which are interconnected. In this case, the connection can advantageously be made by the data processing unit to a measuring system.
- center bearings are designed by single or multiple shared roles as measuring points.
- the data processing unit determines differences in level of the measured variable by means of analytical, statistical evaluation methods and derives therefrom a solidification state.
- the determination of the solidification state takes place by assigning a solidification state to a characteristic measured variable. It is useful if a characteristic
- Measured variable is a bearing force or a bearing deformation. Furthermore, it is Partially, if the determination of the solidification state takes place by assigning a solidification state to a scattering of a characteristic measured variable.
- a scattering of a characteristic measured variable is the scattering of a bearing force or a bearing deformation.
- the data processing unit evaluates the measured variable by means of fast Fourier analysis or other statistical evaluation methods and thus determines the apparatus influences on the measured variable.
- FIG. 1 shows schematically a representation of a cast strand 10 with different solidification states.
- the casting strand 10 is guided by a plurality of strand guiding elements 1.
- the strand guiding elements 1 have rollers 2 which are mounted by means of roller bearings 3.
- the embodiment of Figure 1 schematically four segments 1 are shown, each having five pairs of rollers 2.
- the cast strand 10 is guided by the rollers.
- a first region I the cast strand 10 is in a solidification state which has a degree of solidification of less than 20 to 30%. This means that a liquid or doughy fraction 6 of 80 to 70% is present.
- the casting strand 10 is in a solidification state which has a solidification degree with a solids content of 20 to 80%.
- the cast strand 10 is in a solidification state which has a solidification degree with a solids content of 70 to 80% to less than 100%.
- a solidification state there is correspondingly a solidification state of 100%.
- the sump tip 4 is thus in the last area IV.
- the measured variable representing the roller force lies in a central region in the first region.
- the spread of this measure is at a low level.
- both the measured variable and its scattering are at a high level.
- the measured value is at a low level, but the spread of the measured variable is at a medium level.
- Region I corresponds to the liquid phase of the strand with a liquid core.
- the liquid phase which is in part at a potentially higher level, is burdened by upstream parts of the strand on the strand shell and pushes them from the inside to the outside.
- This ferrostatic must therefore be absorbed by the bearing forces.
- the force is increased in comparison to the solidified state, which means that the measured value representing the force is at an average level.
- the soft strand cushions well so that the stan- dardabwe / chung of the force representing measure is small.
- This first region I ends depending on the steel grade in the range of 20 to 30% solids.
- the region II represents a transition region in which the force level or the level of the measured variable representing the force is at a higher level than in the region I.
- This area has a solidification state of 30 to 70%.
- the strand 10 also has a liquid core with a solid outer region. In addition to the ferrostatic, a proportion of the strand deformation is added. The attenuation of the strand is lower, so that the variance of the force or the force representing the measured variable than in the area I is.
- the region III represents a virtually solidified region in which the force level or the level of the force representing the measured variable perpendicular to the casting direction is low. In this area III only parts of the weight and pull-out force act. The scattering or the standard deviation is high due to the low attenuation of the quasi-solidified strand. In this state, although there is still melt, but separated by bridges and so there is no continuous steel column.
- Region IV is the solidified region in which there are substantially the same force and variance ratios as in region III.
- FIG. 2 shows a diagram in which measurement results are shown, which were obtained at a measuring point which is arranged on a segment of a continuous casting plant.
- different measuring points are not arranged at different segments in this example, but measuring points are used on a segment and the solidification ranges move through the measuring points.
- two measuring points are arranged on a fixed and a floating bearing of a roller bearing.
- FIG. 2 shows in the lower area with the lower two curves the measured values of a a measuring gap representing a force. In this case, a change in the signal representing the force can be detected, and as a result an assignment to the status areas I to III can be made, as explained above.
- the top curve shows the casting speed as a function of time.
- the position of the sump tip or the boundaries between the state regions shifts.
- the state area I with a high liquid content is located at the measuring point.
- the status area II with a medium liquid content is located at the measuring point.
- the state area III is located at the measuring point.
- FIG. 3 schematically shows a continuous casting plant 20 with a cast strand 21 and with six segments 22 to 27.
- the sump tip would be found in the region of the last or possibly also penultimate segment when the casting speed is high. So it may well happen that at high casting speeds of greater than 6 m / min, such as 7 m / min, the sump tip in the last, sixth segment 27 is located. Therefore, it is particularly advantageous to measure the solidification conditions as permanently as possible and to be able to determine their distribution or the position of the sump tip.
- measuring points for example, rollers or roller bearings can be selected, with quite a measuring point on a floating bearing and / or on a fixed bearing a role is selectable. By arranging different measuring points on different rollers, preferably in different segments, an advantageous distribution of the solidification states can be detected.
- the solidification states can be detected.
- the swamp tip is then found, for example, in the sixth segment 26, the hitherto last segment.
- a bearing force measurement is performed.
- the bearing force measurement takes place via an inductive distance measurement, for example in bearing blocks 30, see FIG. 4.
- the measuring bearing blocks 30 are slotted horizontally below the bearing shells 33 by means of slot 32 and equipped with an inductive distance sensor 34.
- the change in the slot height of the slot 34 behaves approximately proportional to the applied force.
- the measuring bearings 30 are installed, for example, in the center bearings of long part rollers 2 and 7 of the segments 24 and 25 on the fixed side and / or on the loose side. In this way, the bearing force is determined at 2 x 4 points distributed over the system length.
- the bearing block 30 of a split center bearing is slotted below the bearing shell, which causes a defined bearing weakening.
- the position and the geometry of the gap are preferably designed so that at maximum load, an advantageous maximum deflection of the gap top side and no plastic deformation occurs.
- the distance sensor 34 is inserted centrally from the bearing foot 35 through a bore 36 into the bearing block 30 and protrudes advantageously into the measuring gap 32.
- the slot 32 is thus designed such that due to the applied force through the cast strand, a local deformation occurs that can be detected.
- the data processing unit 38 can be seen, which receives data from the sensors (34) of the measuring points and determines the solidification states. LIST OF REFERENCE NUMBERS
