Definitions

  • the invention relates to a mold for the continuous casting of metals, preferably of steel, according to the preamble of claim 1 or claim 2nd
  • a mold for the continuous casting of is known from US Pat. No. 4,207,941 Steel strands with polygonal, especially with square Cross sections, known.
  • the cross section of the open on both sides The mold cavity is a square with corner fillets on the pouring side and an irregular one on the strand exit side Twelve corner. In the corner areas, the corner fillet becomes The pouring cone is continuously enlarged in the direction of the strand, and it is in the area of the fillet over a partial length of the mold twice as large as in the central area of the mold wall. At the Pouring with such molds can jam the strand occur within the mold leading to strand breaks and Lead breakthroughs. Also, instead of a square Cast a dodecagon. In particular, it is difficult to use such molds for different casting speeds during one dimensioning the current casting, as in long sequence castings with many pan changes are inevitable.
  • DE-A-3 907 351 discloses a mold with a pouring funnel for a Thin slab described.
  • the two broad sides are on the Pouring side of the mold with bulges that run along a partial height of the mold are continuously reshaped.
  • On the The strand exit side of the mold is the cross section of the mold cavity rectangular and to the desired thin slab cross section aligned.
  • the sole purpose of the two opposite Bulges is the space required to create for a dip tube. Are on the two narrow sides no bulges and no deformation of the strand shell provided by the mold walls.
  • the narrow sides of these Thin slab mold run, in contrast to the two broad sides, the narrow side walls diverging in the direction of the strand.
  • These narrow sides diverging in the direction of the strand are for Solving the task set there, particularly thin strands using one to under the Pouring pouring pipe reaching the pouring level, necessary to bruises and Prevent wrinkles on the broad sides.
  • the invention has for its object the disadvantages mentioned to overcome.
  • deforming the strand cross section within the mold one that can be measured over the entire circumference Cooling of the strand crust can be achieved on the one hand to improve the strand quality and on the other hand the casting speed to increase.
  • there should also be differences in casting speed during a running cast without the above Disadvantages such as strand break and breakthrough are made possible.
  • each mold represents curved lines, compared to classic tubular molds a higher dimensional stability of the mold tube, in particular in the highly heat-exposed bathroom mirror area. This higher dimensional stability improves with tube and other molds on the one hand, the dimensional accuracy of the mold cavity during the Tool life and on the other hand the strand quality.
  • the bulge is usually along the pouring side of the mold cavity over a partial length or over the entire length the mold diminished.
  • At the mold exit for example there is still a curved line in each circumferential section.
  • Cross section of the mold cavity on the mold exit side is additionally proposed to be provided in a straight line on all sides between corners.
  • the mold can also be round or a preliminary profile, e.g. the Form of a double-T beam.
  • the difference between the arc length at the level of the bath level and at the mold exit or tendon length determined at the mold exit and with the shrinkage of the Strand crust compared to the strand running direction compared.
  • the said Difference can be due to the size of the bulge or the arch height be chosen so that they essentially with the shrinkage mentioned is in agreement.
  • According to an embodiment can measure the light between opposite circumferential sections of the mold cavity on the pouring side, in the area measured at the largest bulge, about 5-15%, preferably at least 5% or 8%, greater than the light dimension between opposite ones Circumferential sections on the strand exit side to get voted.
  • the measure of the arc height can be degressive or in the pouring direction possibly shorten progressively and head towards zero.
  • the measure of the arc height can be in Advantageously, continuously decrease the cross-section of the following cross-sections.
  • the change in the bow height in the direction of the strand can according to a further embodiment also as a degree of taper be determined.
  • the shape and the size of the bulge are in all sections the same. Change the conicity of the bulge along the circumferential section in size.
  • An embodiment can at the two ends of each peripheral section a taper between 0 and 1% / m and in the middle the circumferential section is provided between 10 and 35% / m become.
  • Another variation is the choice of length or Partial length of the mold cavity with bulges. It is fundamental possible that the arc height of the bulge over the total mold cavity length reduced. But they are also only partial lengths conceivable. An advantageous embodiment sees one Partial length of at least 50% of the mold length. With today The usual molds of 800 mm in length are at least part of the length 400 mm.
  • the Diagonal measured taper on the partial length with bulges in an order of magnitude between 0 - 1% / m, or between 0 - 0.5% / m to be provided.
  • polygonal Strand cross-sections rounded the corners of the mold cavity. It has proven to be particularly advantageous when the corners of the Mold cavity fillet with a radius of 3 - 8% of the side length of the cross section.
