Definitions

  • the invention relates to a method for guiding a strand in a continuous caster with a soft reduction line, with the hydraulic servo units the jaw width of continuously set opposite strand guide rollers, as well as the corresponding one Strand guidance for this.
  • Continuous casting plants in particular steel continuous casting plants, use to guide the Strand rolls that limit the thickness of the strand that has not yet hardened and prevent bulging of the strand shell as a result of the ferrostatic internal pressure.
  • Such a strand guide is known from DE 40 22 871 C2, in which the scaffolding parts bear opposite strand guide rollers, by means of a Sliding device against each other up to a system of support devices
  • Counter supports can be tensioned with the different altitudes located support surfaces and are provided with counter support surfaces, the individual Support disks are adjustable by twisting.
  • DE-C-3822939 is a strand guide with hydraulically adjustable and regulated pairs of rollers known, these pairs of rollers of each pair of rollers assigned controllers and a higher-level controller can be controlled.
  • the single ones Regulators have valves.
  • the invention has therefore set itself the goal of a method and a corresponding Show device for guiding a strand of a continuous caster, in which the static caused by the four-point bearing of the strand segment Overdetermination avoided and the resulting strain of the Segment lot parts is reduced.
  • the invention achieves this goal by the characterizing features of Process claim 1 and device claim 4.
  • the pair of cylinders switched with only one servo valve has one for each cylinder Position encoder on. From the signals of the individual position sensors to each other linked servo piston cylinder units, an average is formed which is based on the common position controller acting as a position value is fed.
  • the servo piston cylinder units of the Inlet or the outlet of the strand guide segments linked together.
  • the strand guide segments will be linked in the same way, For example, connect all inlets to a position controller and all Control spouts independently.
  • a defined path value for example a specifiable one Distance when determining the mean value or other continuous casting data another pair of servo piston cylinder units can be linked together become.
  • Figures 1 and 2 show a strand guide segment 81 with the Strand guide rollers 82 to 85 or 87.
  • the strand guide direction is through a Arrow indicated.
  • the upper part and the lower part (not shown in the drawing) of the Strand guide frame 81 is formed by four servo piston cylinder units 11, 15, 21, 25 linked together.
  • the servo piston cylinder units 11, 15, 21, 25 have position sensors 12, 16, 22 and 26, which are connected to position controllers 71 to 74 via measuring lines 75 to 77 are.
  • the servo piston cylinder unit 11 with the servo valve 13 the servo piston cylinder unit 15 with the servo valve 17th each individually controllable, while the servo cylinder units 21 and 25 are in the outlet are linked together with the servo valve 27.
  • FIG. 2 shows only the servo piston cylinder units of the inlet 11, 15 or the outlet 23, 25 linked via hydraulic lines 31, 41 or 32, 42.
  • the servo valves 13, 17 with a servo piston cylinder unit 11 are in the inlet area or 15 or can be linked to both.
  • a single servo valve 24 is provided for the servo piston cylinder units 21 and 25 in FIG.
  • This servo valve 24 is linked to a position controller 72, which is connected to the position sensors 22 and 26 by measuring lines 77 and 78.
