Definitions

  • the invention relates to a slitting device for slabs on a continuous casting installation with at least one flame cutting device arranged above a roller table or the like receiving the slab to be cut, which has a burner carriage with a burner that can be moved on rails in the transport direction of the slab, and with a device for relative alignment between the slab and a Brenner career.
  • the burner is mounted in a stationary manner on a portal construction, and the slab must be hydraulically displaced in the transverse direction by so-called aligners and thereby be aligned with the fixed, predetermined burner track.
  • the invention is therefore based on the object of making a slitting device of the type mentioned available, which is characterized by a design characterized by simple, less wear-sensitive training and ensures accurate and safe alignment and guidance of the burner.
  • the invention consists in that, in a slitting device of the type mentioned at the outset, the burner is held displaceably on a boom arranged perpendicular to the direction of transport of the slab and is guided relative to the slab by scanning a device which adjusts the burner track.
  • the device for setting the burner track consists of two movable alignment carriages on which the burner track is fixed.
  • the alignment carriages have a scanning device which, depending on the position of the side edge of the slab, position the alignment carriages on their rails.
  • the device for adjusting the burner career consists of two movable alignment car, which with a ruler are connected, and that a scanning roller is in contact with the ruler, which carries alignment carriages seated on the cantilever, which are connected to the burner carriage.
  • the alignment carriages advantageously have scanning devices that position the alignment carriages on their rails depending on the position of the side edge of the slab.
  • the interconnected carriages are expediently pressed against the ruler by a hydraulic or spring-elastic drive device.
  • a slitting device for a slab 1 to be cut, which rests on a roller table 2 formed by disc-shaped rollers and can be moved in Fig. 1 perpendicular to the plane of the drawing.
  • a burner carriage 10 of the device has wheels 12 which run parallel to the direction of conveyance of the slab on burner tracks 14 and rest on brackets 16 of an alignment carriage 35.
  • the free end of the burner carriage 10 carries a bracket 20 which bridges the slab 1 like a portal and which forms a path for setting a burner 24 transversely to the transport direction of the slab 1.
  • the burner 24 is fastened to a carriage 21 which is guided on the boom 20 by means of guide rollers 23.
  • the burner 24 emits a burner jet 26 from a nozzle located below, through which a longitudinal separation joint 27 is burned into the slab 1.
  • the alignment carriage 35 is guided by means of wheels 48 on rails 37, which are laid below the slab 1 and perpendicular to its direction of transport.
  • a button 42 with a probe 42a is guided horizontally in rolls 43 in the direction of the slab 1.
  • a rack 44 on the button 42 is in engagement with a pinion 45 of a gear motor 46, which is coupled to an electrical displacement sensor is.
  • the probe 42a can be an optically, acoustically or inductively acting probe with a downstream measured value transmitter.
  • the position of the slab can be determined contactlessly, ie avoiding harmful heat transfer, and transferred to a hydraulically or pneumatically actuated actuating cylinder 38 in order to bring the alignment carriage 35 into the position which corresponds to the longitudinal separation joint 27 provided in the slab 1.
  • the burner track is defined by the alignment carriage 35 and transferred to the burner 24 in a simple and exact manner via the scanning roller 42a and the slide 21.
  • a thermal insulation device which is formed by water plates 56 through which a coolant such as water flows.
  • the cutting area of the burner 24 is covered on both sides by a soundproof hood 50.
  • the walls of the noise protection hood are filled with and / or coated with a sound-absorbing material.
  • the soundproofing hood 50 is suspended on a lifting frame 52 which is supported relative to the carriage 21 by a hydraulically or pneumatically actuated lifting cylinder 53.
  • FIG. 3 shows a slitting device, with the aid of which a slab 1 is also slit longitudinally by moving a burner carriage 10 running on the rails 14, which carries the burner 24 on its arm 20.
  • the carriage 21 is coupled via a coupling rod 28 to a second carriage 22, which is likewise guided on the arm 20 by means of guide rollers 23 and on which in turn a coupling rod 29 of a hydraulic or pneumatic actuating cylinder 30 is attached.
  • the movements of both carriages 21 and 22 on the boom 20 are synchronized by the coupling rod 28.
  • a cantilever with a freely rotatably mounted feeler roller 32 which bears against a ruler 33 with a contact pressure predetermined by the actuating cylinder 30, which is held according to FIG. 4 by two alignment carriages 35, of which in the Only one drawing is shown.
  • the alignment carriage 35 ' is guided by means of wheels 48 on rails 49, which are laid below the slab 1 and perpendicular to its direction of transport.
  • a button 42 with a probe head 42a is guided horizontally in rolls 43 in the direction of the slab 1.
  • the alignment carriages 35 ' are brought with the ruler 33 into the position which corresponds to the longitudinal separation joint 27 provided in the slab 1.
  • the ruler 33 displaceable via the alignment carriage 35 ′ is defined, and a transmission via the scanning roller 32 and the two slides 21, 22 to the burner 24 takes place.
  • the heavy boom 20 determining the path of movement of the burner 22 is not touched by this tracking movement, the two alignment carriages 35 'being positioned in the same way at the two ends of the ruler 33.
  • a thermal insulation device 56 and one with a. Lifting frame 52 connected protective hood 50 may be provided.
