Definitions

  • the present invention relates to an adjustment method for a Roller segment of a continuous caster, the one segment entry side and a segment exit side and a pair of roller supports has at least two each over a support area extend extending roles, with the role carrier on a the segment input side and one on the segment output side arranged adjusting unit can be adjusted against each other, whereby each adjusting unit has two arranged on both sides of the support area Has hydraulic cylinder units.
  • Such an adjustment method is, for example, from DE 196 27 336 C1 known.
  • the freezing strand becomes a roller conveyor pulled and supported with a variety of support rollers.
  • the roller conveyor according to DE 196 27 336 C1 in several Divided segments that can be set up separately.
  • the object of the present invention is a pitching method to make available by means of its damage of the roller segment due to excessive force in be avoided in any case and also bulges can be eliminated as far as possible.
  • the object is achieved in that the hydraulic cylinder units both position and pressure controlled are adjustable that The rollers are position-controlled via the hydraulic cylinder units be attached to a metal strand supported by them and that the hydraulic cylinder units from position to pressure controlled Operation can be switched when the pressure in the respective Hydraulic cylinder unit a hydraulic cylinder limit reached.
  • a hydraulic cylinder unit is then preferably also from position-switched to pressure-controlled operation when the Pressure in the other hydraulic cylinder unit of the same actuator reached the hydraulic cylinder limit. This causes in particular essentially a synchronism of the two hydraulic cylinder units every actuator.
  • the adjusting unit has the following effect Changeover from position control to pressure or force control a permanent positive connection between the metal strand and the roles. This measure will bulge the metal strand and possibly avoided its breakthrough.
  • the form fit between the metal strand and the rollers ensures the roller rotation and thus their optimized cooling.
  • the positive locking effect the continuous promotion of the metal strand between the Roll.
  • the hydraulic cylinder limit, the actuator limit, and the segment limit value can preferably be parameterized by the to be able to adapt the structural conditions of the role segment.
  • a roller segment of a continuous caster has two Roller carrier 1,2 with six rollers 3 each.
  • the rollers 3 extend itself over a support area 4.
  • the roller supports 1,2 are with their rollers 3 in the support area 4 to a metal strand 5, here a steel strip 5, employed.
  • the metal strand 5 occurs a segment input side 6 in and on the role segment a segment exit side 7 again from the roll segment.
  • the roller carriers 1, 2 are connected to one another via two adjusting units connected.
  • One adjusting unit has two hydraulic cylinder units 8.9 on that on the segment input side 6 on both sides of the support area 4 are arranged.
  • the other job unit has two hydraulic cylinder units 10, 11 on the Segment output side 7 arranged on both sides of the support area 4 are.
  • Each of the hydraulic cylinder units 8 to 11 is both positionally as well as adjustable pressure. Each of the hydraulic cylinder units 8 to 11 are therefore, according to FIG. 2, pressure sensors 12, 13 and Position encoder 14 assigned. Their output signals are on a computing unit 15 transmits. The computing unit 15 determines then control signals for the hydraulic cylinder units 8 to 11 and outputs this to control valves 16, so that the hydraulic cylinder units 8 to 11 can be moved to employment.
  • all hydraulic cylinder units 8 to 11 move so that the rollers 3 of the roller carrier 1,2 can be adjusted to position the metal strand 5.
  • the hydraulic cylinder units 8 to 11 are per adjusting unit controlled synchronously.
  • the jobs that the Hydraulic cylinder units 8 to 11 can be set determined independently of one another by the computing unit 15.
  • the computing unit 15 does this determined and given to the hydraulic cylinder units 8 to 11, that force-related suspensions (e.g. the roller carrier 1, 2) be compensated.
  • the position-controlled employment of the roles 3 to the metal strand 5 remains until - z. B. due a bulge in the metal strand 5 - the pressure in one of the Hydraulic cylinder units 8 to 11, e.g. B. the hydraulic cylinder unit 8, reached a hydraulic cylinder limit. If the Pressure in this hydraulic cylinder unit 8 a hydraulic cylinder limit reached, this hydraulic cylinder unit 8 is on pressure-controlled operation switched.
  • the hydraulic cylinder unit 8 then maintains the pressure at the hydraulic cylinder limit and so dodges.
  • any of the hydraulic cylinder units 8 to 11 to be regulated independently of each other.
  • the hydraulic cylinder units 8 to 11 of the adjusting units however switched in groups.
  • With the hydraulic cylinder unit 8 is also used as the hydraulic cylinder unit 9 switched from position to pressure-controlled operation.
  • the hydraulic cylinder units 8 and 9 switched from position to pressure-controlled operation, when the sum of the pressures in the hydraulic cylinder units 8 and 9 reaches a decimal unit limit.
  • the Hydraulic cylinders 10 and 11 from position to pressure controlled Operation switched when the sum of the pressures in the hydraulic cylinder units 10 and 11 reached the decimal unit limit.
  • all 4 hydraulic cylinder units 8 to 11 simultaneously switched from position to pressure-controlled operation, if the sum of the pressures in the hydraulic cylinder units 8 to 11 reached a segment limit.
  • the hydraulic cylinder limit, the actuating unit limit and / or the segment limit value can preferably be parameterized, to adapt it to the specific circumstances of the role segment to be able to.
  • the limit values can be parameterized in such a way that overloads of the roller carrier 1,2, the rollers 3 and the Not shown roller journal of the rollers 3 and also bearings for the roller journals, not shown, can be avoided.
