Definitions
- the invention relates to a method and a roller segment for determining the core solidification and / or the sump tip in the continuous casting of metals, in particular of steel materials, within a roller segment of a support roller frame, the upper rollers supporting the upper frame via disposed in the corners of a polygon hydraulic piston-cylinder units be set against the sub-rolls of a sub-frame to the respective strand thickness drivingly.
- each segment frame is divided into two parts and the frame parts are clamped together by means of hydraulic piston-cylinder units.
- each roller segment has four hydraulic cylinders which clamp in pairs opposing rollers for supporting and promoting the solidifying casting strand. At least one of these rollers is pressed as a drive roller for transferring the strand conveying forces with a defined contact force against the cast strand.
- the roller gap between the roller conveyor of the fixed side and the roller conveyor of the loose side is detected by hydraulic cylinders with integrated electronic encoders or position sensors, measured and, if necessary, regulated.
- a determination of the position of the sump tip in the interior of the casting strand takes place via the movement of the entire upper frame and / or an evaluation of the four position values in conjunction with the resultant force values of the four hydraulic cylinders. It has been found that this method of determining the sump tip and the preceding regions is not sufficiently accurate. In addition, the cost of non-position-controlled roller segments is very high.
- the measured values for position or force rules for determining the position are determined by an independent pair of piston-cylinder units with external measuring device or internal measuring device for adjusting a rotationally driven, single top roller the core solidification and / or the sump tip are taken into account in the cast strand.
- the obtained measurement results are advantageously used as a basis for extended procedural processes and functions for the operation and optimization of the setting parameters of the continuous casting and the continuous casting plant.
- the specification of a position value with subsequent evaluation of the resulting force or specification of the force values with subsequent evaluation of the resulting position can be used as process-technical feedback of the strand properties or the position of the sump tip.
- the determination of the exact position of the sump tip here can be improved in accuracy in contrast to the previously known approach to use the entire upper frame for measurement.
- the application relates to position-controlled segments and independent installation for segments without position control. The equipment is made cheaper.
- a presetting of an increased accuracy can be carried out according to further features in that the measured values are measured simultaneously on several (selected) roller segments with at least one pair of independent piston-cylinder units and all measured data are processed to a mean value.
- the mechanical solution of the invention task is achieved in that in the upper frame an independent, for fastening an external Messeeinrich ⁇ device or at least a pair of hydraulic piston-cylinder units serving traverse is provided with a rotationally driven, individual upper roller for Mes ⁇ solution of the data for the cold strand or the hot extruding force.
- the traverse can be designed with one or two hydraulic piston-cylinder units.
- the piston-cylinder units are regulated in their position.
- position sensors are integrated into the cylinders or an external measuring device is attached to the crossbeam.
- a control system adopts the determined position values and regulates the desired cylinder position via a hydraulic valve.
- the individual role can be regulated in the contact force.
- pressure sensors are installed in the hydraulic cylinders (in both cylinder chambers) or in connecting lines (between control valve and cylinder). The cylinder set forces are controlled by the hydraulic control valve.
- One embodiment provides that with an overall odd number of upper rollers and lower rollers, at least one middle upper roller and the opposite lower roller are driven.
- roller segment with the features according to the invention in the casting direction as the last roller segment of the support roller frame.
- position-controlled traverses as the last framework of a support roll stand, an optimization of the casting speed with maximum utilization of the continuous casting plant and maximum throughput is possible.
- a risk due to bulging of the strand behind the continuous casting device at too high a set casting speed at which the liquid bottom leaves the strand guide is thereby avoided.
- FIG. 1 shows an upper roller segment in perspective in an exploded view
- FIG Fig. 2 is a perspective view of a unit of upper frame
- Subframe which forms a Stütz ⁇ roll stand in succession in a row.
- FIG. 1 and 2 show a roller segment 1 and Fig. 2, the roller segment 1 in the installed state in a part of the support roller frame 2.
- An upper frame 3 carries the upper rollers 4.
- In the corners 5a, 5b, 5c, 5d of a polygon are hyd ⁇ Raulische piston-cylinder units 6 mounted and connected to a sub-frame 7 via the piston.
- the subframe 7 carries the lower roller 8.
- the upper rollers 4 are in part lengths 4a, 4b and the lower rollers 8 in part lengths 8a, 8b executed and rotatably supported respectively by means of inner bearings 11 and outer bearings 12 and internally cooled.
- the method for determining the core solidification and / or the position of the sump tip in the continuous casting of metals, in particular Stahlwerkstof ⁇ fen, is exercised such that an independent of the top rollers 4 and lower rollers 8, external measuring device 13 or at least one of the übri ⁇
- an independent of the top rollers 4 and lower rollers 8 external measuring device 13 or at least one of the übri ⁇
- the measured values for position or force rules for determining the position of Core solidification and / or the position of the sump tip in the cast strand are taken into account.
- the f ⁇ driven single upper roller 4 has an upper stub shaft 15 and the opposite not engageable lower roller 8 a lower Wellen ⁇ stump 16, to the respective rotary actuators (not shown) are connected.
- the measured values at a plurality of roller segments 1 with at least one respective pair 14 of independent piston-cylinder units 14a, 14b can be measured simultaneously and all measured data can be processed to a mean value.
- the traverse 20 is equipped with lifting lugs 21, so that a structural unit consisting of the individual upper roller 4, the independent pair 14 of piston-cylinder units 6 and the measuring device 13 can be lifted or inserted by crane.
- the pair 14 of the two piston-cylinder units 6 is connected via joints 22.
