Definitions

  • the invention relates to a device for adjusting opposite guide segments of a continuous casting or Casting mill in preferably three different Positions, each with a leadership segment with a Hydraulic cylinder and the opposite guide segment are connected to the piston rod, the piston double acting and at least one of the three Positions through a stop surface inside the cylinder is set.
  • EP 0 545 104 B1 describes a device and a method for continuous casting of slabs or blocks in one Continuous caster with a soft reduction line described individually or as a segment Hydraulic cylinders interchangeable and by means of Spindles in their clear distance (mouth width) to each other has continuously adjustable rollers. This facility allows by relieving the pressure of the spindles by means of suitable Hydraulic systems a stepless adjustment of the distance of the Roll, but it is complex and prone to failure.
  • DE 195 11 113.2 describes a strand guide Continuous caster for thin slabs, with guide rollers on opposite frames are stored by tie rods are braced against stop surfaces.
  • tie rods are braced against stop surfaces.
  • the distance is infinitely variable the frame, but only in a small area through which the Use of this solution is restricted.
  • DE 43 06 853 A1 proposes a strand guide Continuous casting plants for the production of slabs, especially after described the casting and rolling process, with different Strand thicknesses adjustable, in pairs opposite rollers, the frame or scaffold parts connected by tie rods the strand guide and their tie rods from piston-cylinder units are educated and in the power flow the piston-cylinder unit between the upper and lower Frame parts spacers are inserted.
  • the strand so that especially when Casting rolls of thin slabs in the partially solidified area Setting leadership roles in three defined positions is possible, it is suggested that between spacers and the cylinder of the piston-cylinder unit Hydraulic ring cylinder is arranged on the piston rod surrounds and the annular piston the spacer non-positively wearing.
  • the invention has for its object a generic To create device with which the distance from opposite guide segments of continuous casting or Casting and rolling systems is easily adjustable.
  • the task is solved by old three positions different positions of the piston correspond and by Stop surfaces of the hydraulic cylinder are set, and that at least one of the stop surfaces outside the Hydraulic cylinder is arranged.
  • the summary of the Stopping surfaces on the hydraulic cylinder offer structural advantages and the location of stop surfaces or stops outside the Hydraulic cylinders facilitate their accessibility and possible adjustment.
  • An advantageous embodiment of the invention is that the hydraulic cylinder is arranged on the outside of one of the opposite guide segments and is attached to it at the cylinder end from which the first piston rod protrudes, which is fastened to the opposite guide segment. In this way, the hydraulic cylinder is easily accessible. At its free end, it also offers space for external stop surfaces and stops.
  • the hydraulic cylinder is a first End wall and a second end wall, which as serve first and second inner stop surfaces for the piston, the first end wall additionally having a flange or a pivot pin to attach the hydraulic cylinder one of the opposite guide segments.
  • Attaching the hydraulic cylinder to the side of the Projecting the first piston rod allows that on the free side of the piston attached to a second piston rod can be in a second central pilot hole the second end wall is guided and at its free end has a first outer stop. This makes room for an easily accessible outer stop.
  • An advantageous development of the invention consists in that an annular piston that has a first outer stop surface for has the first outer stop, in one Cylinder extension of the hydraulic cylinder and on the second piston rod sealingly and axially displaceable is.
  • the displaceability of the ring piston makes it suitable this as the first outer stop surface for the middle one Position of the piston, since the ring piston lacks oil pressure can be pushed over to reach the inner position of the piston is.
  • the working position of the ring piston is determined by that a collar on the inner circumference of the cylinder extension is provided, which together with one on the outer circumference of the Piston arranged shoulder as its outer Stroke limitation is used.
  • the three positions of the piston of the invention Device are adjusted by both sides of the Piston and one side of the ring piston separated are pressurizable.
  • An advantageous embodiment of the invention is that instead of the second, inner stop surface, a second one outer stop surface for the second outer stop trained free end of the second piston rod provided is preferably formed as a pot and with the free End of the cylinder extension is detachably connected. To this There are two stops or stop faces of the piston externally accessible and influenceable. This fact is particularly interesting if at least the first outer Stop, and the second outer stop surface adjustable are.
  • a hydraulic cylinder 1 is shown in FIGS. 1a, 1b, 1c a first end wall 2 and a second end wall 3 and a cylinder tube 4, which is a Cylinder extension 4a connects.
  • the first end wall 2 carries a flange 5, which is used to attach the Hydraulic cylinder 1 on the outside of a first Guide segment of a continuous casting or casting rolling plant is used.
  • the first has inside the hydraulic cylinder 1 End wall 2, a first, inner stop surface 6 and the second end wall 3 a second, inner stop surface 7 for a double-acting piston 8 in the hydraulic cylinder 1 is sealed.
  • the piston 8 is on its first side 9 with a first Piston rod 10 and on its second side 11 with a second piston rod 12 firmly connected.
  • the first piston rod 10 is in a first central guide bore 13 of the first End wall 2 and the second piston rod 12 in one second central guide bore 14 of the second end wall 3 sealing led.
  • the first piston rod 10 carries one at its free end Rod end 15, which is articulated with a second guide segment connected is.
  • the second piston rod 12 carries on free end a first outer stop 16 through which the Piston 8 can be fixed in a middle position.
  • the to the first outer stop 16 belonging to the first outer Stop surface 17 is part of an annular piston 18 which in one Cylinder cover 4b and sealing on the second piston rod 12 is led.
  • the annular piston 18 is axially displaceable educated. Its inner stroke is through the second end wall 3 limited. Its outer stroke and thus the location of the first outer stop surface 17, is by a collar 19 on Inner circumference of the cylinder cover 4b together with a shoulder 20 set on its outer circumference.
  • the first, outer stop 16 is adjustable Execution shown, with an adjusting nut 21, one Stop ring 22 and a washer 23 together screwable against a shoulder of the second piston rod 12 are. Due to washers 23 of different thicknesses first outer stop 16 adjustable.
  • the second outer stop surface 25 is also by changing others of different thicknesses Washers 23 'adjustable.
  • the device according to the invention functions as follows:
  • the outer position of the piston 8 shown in Fig. 1a on the first inner stop surface 6 is caused by the oil pressure causes that prevails only in a second oil pressure chamber 28.
  • This position of the piston 8 corresponds to the largest distance Guide segments or roles.
  • the inner position of the piston 8 shown in Fig. 1c on the second inner stop surface 7 is caused by oil pressure, which only exists in a first oil pressure chamber 27. This location of the piston 8 corresponds to the minimum distance Guide segments or roles.
  • the setting of the three positions of the guide segments happens purely hydraulically.
  • a possible setting of the first outer stop 16 or the second outer stop Stop surface 25 (Fig. 2) can without intervention in the hydraulic system can be realized.
