Definitions

  • the invention relates to a method for the continuous casting of steel according to the preamble of claim 1.
  • the invention has for its object to avoid the existing difficulties and to provide measures with which a trouble-free operation of a continuous caster for flat slabs is possible.
  • a distribution channel with immersion spouts and a height adjustment by a lifting device is known, the lifting device being program-controlled.
  • the adjustability serves to determine a specific predetermined pouring position of the distributor or the immersion spout.
  • the system described there is operated with a mold level control.
  • the lifting device and the mold level control work independently of each other.
  • Stahl und Eisen (1988), pages 284 to 285, describes a control device for distributors with immersion spouts in the case of small billet formats, the pouring and height adjustment of the distributor being included in the control during the casting.
  • the height adjustment of the distributor is used to influence the wear of the immersion spout in the slag zone.
  • the steel flows out of a distributor 1, which is mounted for height adjustment on hydraulic cylinders 2, through the immersion nozzle 3 into a mold 4.
  • the immersion nozzle 3 protrudes into the mold 4 during casting to below the bath level 5.
  • the mold is provided with a bath level measuring device 8 consisting of transmitters 6 and receivers 7, which is also able to monitor the start-up process, ie the filling of the mold with melt.
  • the filling and further pouring process can be controlled by a slide closure 9 arranged below the distributor 1, which is adjusted to a specific flow rate by means of a hydraulic cylinder 10 is adjustable.
  • the control is carried out via a slide control 11.
  • the height of the distributor 1 can be regulated by influencing the hydraulic cylinders 2 by means of a position controller 12.
  • the height controller 12 cooperates with a measuring device 13 which determines the height of the distributor 1.
  • the strand withdrawal speed is also measured at 14.
  • the measured values about the position of the slide, the bath level in the mold and the transport rollers are fed to a bath level controller 15 and controlled by this controller 15 according to predetermined values.
  • the bath level controller 15, the position controller 12 of the distributor and the measuring device 13 for the height of the distributor are connected to a superordinate guide controller 16, into which data on the temperature of the steel and the steel quality are also fed.
  • the factor K takes into account the temperature and quality of the steel, as well as the strand withdrawal speed and the position of the casting level.
  • the invention is of course also applicable to distributors without stopper or slide control of the outflow.
