Definitions

  • the invention relates to a method for producing steel strip, wherein a continuously cast steel strip, which consists of a solidified strand shell and a liquid core, is reduced in thickness in a roll deformation and then rolled.
  • the thickness of the strand shell formed essentially depends on the casting speed.
  • the rolling force must be adapted to the current strand shell thicknesses. If the casting speed is too low, the available rolling force is no longer sufficient, so that the target thickness of the steel strip produced is exceeded. If the casting speeds are too high, welding of the strand shells can only be achieved by falling below the target thickness of the steel strip produced.
  • the object of the invention is to provide a method and a system for carrying out the method, undesired thickness deviations of the steel strip produced being avoided and a good structure being achieved.
  • the aim is to simplify the deformation unit and to reduce its energy consumption.
  • the object is achieved according to the invention in that a steel strip strand of 40-80 mm thickness is cast, the steel strip strand is roll-deformed to a maximum of 15-40 mm thickness and 2-15 mm residual liquid core in a maximum of three stages, and then the steel strip strand is solidified is guided without deformation.
  • casting speed and strip thickness can be freely assigned to each other to achieve high production performance.
  • a core-tight and segregation-free structure is achieved.
  • the reduction in the contact force of the deformation unit results in a structural simplification and an energy saving.
  • the thickness of the strand shell is advantageously 6-19 mm before the roll deformation.
  • the degree of roll deformation is 10-60% and can be changed during the casting.
  • the roll-formed strand is guided in parallel over a length of 1 - 5 m.
  • the steel strip After solidification, the steel strip is set to the rolling temperature and rolled.
  • a maximum of three pairs of deforming rollers are arranged downstream of a solidification section consisting of support rollers and a drive device.
  • the shaping rollers and / or support rollers are provided with a mechanical positioning device and a hydraulic pressing device.
  • the steel strip 1 consists of a mold 1 for casting a steel strip strand 2 of 40-80 mm thickness, a pair of deforming rollers 5, guide rollers 7 and drive rollers 8.
  • a bending roller 9 is provided for deflecting the steel strip.
  • the steel strip 2 'then passes into a driving straightening device 10 and can be divided by scissors 11. To adjust the temperature, the steel strip sections then pass through a furnace 12, which is followed by a further pair of scissors 13 and a descaling device 14.
  • a Steckel rolling mill arranged in the material flow consists of a roll stand 15 with upstream or downstream reel furnaces 16, 17.
  • the rolling strip 2 ′′ leaving the Steckel rolling mill passes through a laminar cooling section 18 and is then wound up on a reel 19.
  • Figures 2-4 of the drawing show the manufacturing steps of the steel strip 2, 2 'in the continuous casting plant.
  • a cast strand 2 with a liquid core 4 is formed in the mold 1 by cooling and solidifying the strand shell 3 from the cast steel melt.
  • the strand shells 3 located on the broad broad sides are reduced in their mutual spacing by the deforming rollers 5 (6) provided with internal cooling 35. In this way, a strand of 15-40 mm thickness with 2-15 mm residual liquid core 4 is produced.
  • the roll-shaped casting strand 2 is guided between the roller tracks formed from guide rollers 7 without deformation, which leads to solidification.
  • the strand conveyance is effected by the drive rollers 8.
  • the casting strand 2 is roll-formed in one step between a pair of shaping rollers 5.
  • a two-stage roll deformation takes place between the deforming roller pairs 5 and 6.
  • a two- or three-stage roll deformation is advantageous for steels that do not allow a high deformation rate or a high deformation level.
  • the casting strand below the mold is first guided without deformation between support rollers 21 to set a quality-specific temperature.
  • the support rollers 21 and the guide rollers 7 have internal cooling 22 and 23, respectively.
  • the deforming rollers 5 are interposed several times, the bearings 24, 25 being fastened to cross members 27, 28 which are guided on stands 26 on opposite sides.
  • spindle gear 29 are attached to the stands.
  • the spindle gears 29 connected to a motor 30 each have a threaded spindle 31 in the direction of the cross members 27, 28.
  • a spacer nut 32 screwed onto a threaded spindle 31 is secured against rotation by a feather key 33.
  • Each spacer nut 32 is assigned a stop plate 34 on the cross members 27, 28.
  • the crossbeams 27, 28 are pulled towards one another by adjusting cylinders 36, each with a pull rod 36a, their mutual spacing and thus the spacing of the deforming rollers 5 being determined by the spacer nuts 32 set by the spindle gear 29. In this way it is achieved that the pair of deforming rollers 5 with a distance adjustment to the mold space of the mold 1st stays centered. Appropriate storage and adjustment is provided for further pairs of deforming rollers 6 (FIG. 3).
  • the guide rollers 7 are also temporarily stored several times, the bearings 37, 38 being mounted on frames 39, 40.
  • the frames 39, 40 are guided on stands 41 on both sides.
  • spindle gear 42 As a positioning device for the frames 39, 40 and guide rollers 7 41 spindle gear 42 are attached to the stands.
  • the spindle gears 42 connected to a motor 43 each have a threaded spindle 44 in the direction of the frames 39, 40.
  • Each spacer nut 45 screwed onto a threaded spindle 44 is secured against rotation by a feather key 46.
  • Each spacer nut 45 is assigned a stop plate 47 on the frames 39, 40.
  • the frames 39, 40 are pulled towards one another by adjusting cylinders 48, each with a pull rod 48a, their mutual spacing and thus the spacing of the guide rollers 7 being determined by the spacer nuts 45 set by the spindle gear 42. In this way it is achieved that the guide rollers 7 remain aligned with the corresponding deforming rollers 5 when the distance is adjusted.
