Definitions
- the present invention relates to an adjustment method for a roller segment of a continuous casting installation, which has a segment input side and a segment output side and a pair of roller carriers, each of which carries at least two rollers extending over a support area, the roller carriers having one arranged on the segment input side and one on the segment output side Adjusting unit can be adjusted against each other, each adjusting unit having two hydraulic cylinder units arranged on both sides of the support area.
- Such an adjustment method is known, for example, from DE 196 27 336 Cl.
- the solidifying strand is drawn off and supported via a roller conveyor with a large number of support rollers.
- the roller conveyor according to DE 196 27 336 Cl is divided into several segments, which can be set up separately.
- the metal strands which are still hot, and which have not yet solidified in a core area, can bulge.
- a greater force is exerted on the segment than usual. Under certain circumstances, this can lead to damage to the roller segment.
- the bulge must be compensated for in the further processing of the metal strand.
- the object of the present invention is to provide an adjustment method by means of which damage to the roller segment due to excessive forces can be avoided in any case and, furthermore, bulges can be eliminated as far as possible.
- the object is achieved in that the hydraulic cylinder units can be adjusted both in a position-controlled and pressure-controlled manner, that the rollers are position-controlled placed on a metal strand supported by them and that the hydraulic cylinder units are switched from position-controlled to pressure-controlled operation when the pressure is in of the respective hydraulic cylinder unit reaches a hydraulic cylinder limit.
- a hydraulic cylinder unit is preferably also switched from position-controlled to pressure-controlled operation when the pressure in the other hydraulic cylinder unit of the same actuating unit reaches the hydraulic cylinder limit value. In particular, this essentially causes the two hydraulic cylinder units of each adjusting unit to synchronize.
- the adjustment unit after switching from the position control to the pressure or force control a permanent positive connection between the metal strand and the rollers.
- This measure avoids bulging of the metal strand and, if necessary, its breakthrough.
- the positive connection between the metal strand and the rollers ensures the roller rotation and thus its optimized cooling. Furthermore, the positive connection causes the continuous conveyance of the metal strand between the rollers.
- the hydraulic cylinder limit value, the adjusting unit limit value and the segment limit value can preferably be parameterized in order to be able to adapt them to the structural conditions of the roller segment.
- Figure 1 is a roller segment of a continuous caster
- Figure 2 shows a control circuit for controlling the roller segment.
- a roller segment of a continuous caster has two roller carriers 1, 2 with six rollers 3 each.
- the rollers 3 extend over a support area 4.
- the roller supports 1, 2 are set with their rollers 3 in the support area 4 against a metal strand 5, here a steel strip 5.
- the metal strand 5 enters the roller segment on a segment input side 6 and exits the roller segment on a segment output side 7.
- the roller carriers 1, 2 are connected to one another via two adjusting units.
- One adjusting unit has two hydraulic cylinder units 8, 9, which are arranged on the segment input side 6 on both sides of the support region 4.
- the other adjusting unit has two hydraulic cylinder units 10, 11, which are arranged on the segment output side 7 on both sides of the support area 4.
- Each of the hydraulic cylinder units 8 to 11 can be position and pressure controlled. Each of the hydraulic cylinder units 8 to 11 are therefore assigned pressure sensors 12, 13 and position sensors 14 according to FIG. Their output signals are transmitted to a computing unit 15. The computing unit 15 then determines control signals for the hydraulic cylinder units 8 to 11 and outputs them to control valves 16, so that the hydraulic cylinder units 8 to 11 are moved to positions.
- all hydraulic cylinder units 8 to 11 are moved such that the rollers 3 of the roller carriers 1, 2 are positioned on the metal strand 5 in a position-controlled manner.
- the hydraulic cylinder units 8 to 11 are controlled synchronously per adjusting unit.
- the positions to which the hydraulic cylinder units 8 to 11 are set are determined independently of one another by the computing unit 15.
- the positions are determined by the computing unit 15 and given to the hydraulic cylinder units 8 to 11 in such a way that spring deflections caused by force (for example the roller carrier 1, 2) are compensated for.
- the position-controlled employment of the rollers 3 on the metal strand 5 remains until - z. B. due to a bulge in the metal strand 5 - the pressure in one of the hydraulic cylinder units 8 to 11, for. B. the hydraulic cylinder unit 8, a hydraulic cylinder limit value is reached.
- this hydraulic cylinder unit 8 is switched to pressure-controlled operation.
- the hydraulic cylinder unit 8 then maintains the pressure at the hydraulic cylinder limit and thus evades.
- each of the hydraulic cylinder units 8 to 11 independently of one another in this way.
- the hydraulic cylinder units 8 and 9 are switched from position-controlled to pressure-controlled operation when the sum of the pressures in the hydraulic cylinder units 8 and 9 reaches a setting unit limit.
- the hydraulic cylinders 10 and 11 are switched from position-controlled to pressure-controlled operation when the total of the pressures in the hydraulic cylinder units 10 and 11 reaches the adjusting unit limit.
- all 4 hydraulic cylinder units 8 to 11 are simultaneously switched from position-controlled to pressure-controlled operation when the sum of the pressures in hydraulic cylinder units 8 to 11 reaches a segment limit.
- the hydraulic cylinder limit value, the adjusting unit limit value and / or the segment limit value can preferably be parameterized in order to be able to adapt them to the specific circumstances of the roller segment.
- the limit values can be parameterized in such a way that overloading of the roller carriers 1, 2, the rollers 3 and the roller journals of the rollers 3, not shown, and the bearings for the roller journals, also not shown, are avoided.
