Definitions

  • the present invention relates to a method for operating a continuous casting machine at casting start, at the end of casting and at a temporary slowing down of the casting operation.
  • US 4,169,498 A discloses a reduction of the casting speed, the amount of coolant per time in [l / min] and the amount of coolant per strand surface in [l / m 2 ] as a function of the time at casting start and casting end.
  • continuous casting machine covers all casting machines which are suitable for the continuous production of a strand with a long or flat product cross section from a molten steel.
  • the invention is based on the recognition that the strand ends, i. the strand beginning and strand end being colder than the intervening strand (hereinafter also referred to as strand main part) which is continuously cast at nominal casting conditions. This is mainly due to the reduced casting speed at the casting start and casting end.
  • heat is transferred via the cold strand or through the water, which in addition to the strand end or the strand board, i. the end face of the Strangendes, arrives, dissipated. Because of the lower temperature, the strand ends i.A. completely solidified.
  • roller forces can be far above the maximum permissible values of the roller bearings and thus lead to damage of the rollers or the roller position.
  • the pair After the strand beginning, or preferably the upper end of the strand beginning region having a length of length A, 0.5 ⁇ A ⁇ 5 m, has passed through a pair of engageable strand guide rolls, the pair is turned to the strand so that the pair touches the strand , Furthermore, the strand start region is cooled less by a cooling nozzle than the strand main part, which adjoins the strand start region; Specifically, the strand start region is cooled with a coolant quantity Q ⁇ Q nominal and the strand main part with a coolant quantity Q ⁇ Q nominal . Thus, the strand beginning is "softer cooled" in the language of the art as the strand main part.
  • the temperature of the strand start region corresponds more closely to the temperature of the strand main part, which is poured continuously at nominal casting conditions.
  • the pair of opposed strand guide rolls on the strand and the strand through at least one cooling nozzle in the region of the pair of employed strand guide roller with the nominal coolant quantity Q Nenn cooled.
  • a strand guide roller of a strand guide segment which is made by the inclination of the clamping cylinder of the segment, or a strand guide roller, which by a (see, eg WO01 / 94051 ) or two Anstellzylinder is hired to the strand understood.
  • the rated coolant quantity Q Nenn is preferably dependent on the casting speed, the strand age or particularly preferably on the location-dependent strand temperature.
  • Q rated is smaller at a low casting speed than at a higher casting speed.
  • the strand temperature can be determined either by measurement (eg by means of a pyrometer) or by online simulation of the strand temperature (eg by the software package Dynacs or Dynacs 3D).
  • the amount of coolant Q discharged from the cooling nozzle to the strand start region is increased as a function of a distance between the strand start and the cooling nozzle, where Q ⁇ Q nominal .
  • Increasing the amount of refrigerant causes the temperature of the strand start region to be adjusted reasonably evenly to the temperature of the strand main body continuously poured at nominal casting conditions.
  • the increase in the amount of coolant can be done either continuously or in discrete steps.
  • the distance should be understood as the difference between the so-called metallurgical lengths.
  • the strand is reduced by the employment of the pair of engagable strand guide rollers to the strand in its thickness.
  • the strand has a liquid core in the reduction of its thickness. This will cause u.A. also reduced the forces in the reduction.
  • a strand end is formed in the mold, followed by a strand region with a length B and a strand main part in the casting direction.
  • the position of the strand end in the strand guide is in turn detected.
  • the pair of engagable strand guide rollers are replaced by the strand end, Preferably, before a lower end of the strand area, the couple has passed, pulled back from the strand, so that the two strand guide rollers no longer touch the strand (positively formulated means that both strand guide rollers spaced from the surface of the strand).
  • the strand body is cooled substantially with the nominal coolant quantity Q nominal ; the line section is cooled with a coolant Q ⁇ Q Nenn and the end of the line is cooled with coolant Q ⁇ Q Nenn .
  • Weaker cooling of the strand area tends to adjust the temperature of this area to the temperature of the strand body, improving the quality.
  • the coolant quantity Q discharged from the cooling nozzle is reduced as a function of a distance between the strand end and the cooling nozzle, where 0 ⁇ Q ⁇ Q nominal .
  • transition piece By reducing the amount of liquid steel supplied and the reduction of the pullout pullout speed resulting from the continuity, a so-called transition piece is formed in the strand, which is considerably colder than the strand main part. Damage to the strand guide is prevented by retracting a pair of engageable strand guide rolls prior to passing the transition piece such that the strand guide rolls do not contact the transition piece. After passing the transition piece, the pair is put back on the strand so that the rolls of the pair touch the strand. Because the transition piece is less strong (“softer”) is cooled as the strand main parts, the temperatures of the transition piece and the strand main parts are at least partially adjusted. This increases the quality of the transition piece.
