Definitions

  • the invention relates to a strand guide segment of a continuous casting installation, comprising an upper frame and a lower frame, hydraulic cylinder units for adjusting the distance between the upper frame and the lower frame being arranged between the upper frame and the lower frame, part of the hydraulic cylinder unit being connected to the upper frame via a first bearing point and part of the hydraulic cylinder unit is connected to the subframe via a second bearing point.
  • the housing element is preferably attached to the upper frame by means of the flange.
  • the housing element with the bearing rings located therein is preferably designed as an encapsulated unit.
  • a sensor for detecting the displacement between the piston and cylinder of the hydraulic cylinder unit is preferably arranged on or in the housing element.
  • a preferred embodiment of the invention provides that the sensor is arranged on or in the housing element in the region of the longitudinal axis of the hydraulic cylinder unit. It is particularly preferably provided that the sensor is designed to detect the movement of a rigid measuring rod which is connected to the piston of the hydraulic cylinder unit.
  • the present invention is based on the arrangement of the axial bearings in an encapsulated bearing block which has a base plate (flange) with which the low-play connection of the cylinder unit in the upper frame of the segment is possible.
  • the senor for position measurement above the cylinder unit is mounted centrally in the pull rod of the hydraulic cylinder unit.
  • a segment for the strand guidance in a continuous casting installation is made available, which is characterized by a low-play connection of the upper frame to the lower frame of the segment.
  • the hydraulic cylinder units 4 are position-controlled so that a precise distance between the upper frame 2 and the lower frame 3 can be set and maintained.
  • Hydraulic cylinder unit 4 is connected to the subframe 3 at a second bearing point 6.
  • the first bearing 5, with which the hydraulic cylinder unit 4 is fixed to the upper frame 2 is designed in a special way:
  • Said bearing point 5 comprises a bearing 7, which in the exemplary embodiment has two inner rings 8 and 9 and two outer rings 10 and 11.
  • the bearing 7 is designed in the manner of an axial sliding bearing.
  • a part of the hydraulic cylinder unit 4 is connected to the two inner rings 8 and 9 such that a radially widened section 14 of a part of the hydraulic cylinder unit 4 is axially enclosed by the two inner rings 8, 9 (see Figure 2 ).
  • the two outer rings 10 and 11 are, however, arranged in a hollow cylindrical housing element 12 with an axial spacing and fixed therein, the housing element 12 forming a closed position unit which supports the axial end of the pull rod 21 of the hydraulic cylinder unit 4.
  • a flange 13 is fixedly connected to the housing element 12 and is secured with a number of screws 24 (see also Figure 1 ) is attached to the upper frame 2.
  • the piston 22 of the hydraulic cylinder unit 4 is connected to a piston rod 23 which is connected to the lower tie rod 18 by means of a flange device 19.
  • a sensor 15 is provided, which is arranged centrally above the pull rod 21 and thus centrally on or in the housing element 12. This sensor 15 is designed to detect the displacement of a rigid measuring rod 16 and thus the current deflection of the hydraulic cylinder unit 4.
