Definitions

  • the invention relates to a continuous casting mold for casting relatively thin strands made of metal, especially steel with comparatively high casting speeds and a method for producing thin metal strips with the same Continuous casting.
  • the advantage of the casting and rolling process is that the strip is for one row of applications is already operational.
  • the hot rolling of the strip can omitted.
  • the structure of the tape ensures for a number of applications the required mechanical properties. They are of further advantage small dimensions of the casting machine and the ability to wind up the tape to be able to.
  • Rapid wear of the side seals is particularly disadvantageous and the difficulty, the required geometric accuracy of the tape to be observed because the rollers deform due to the high thermal load.
  • the main feature is the mold with funnel-shaped pouring area, which on the sides towards the format of the cast Stranges is reduced. In the casting direction, the pouring area can at least extend to the lower edge of the mold.
  • pinch rollers in the Strand guidance can reduce the strand thickness, for example, to 40 mm and less become.
  • the aim of the present invention is now to provide a continuous casting mold and a Name procedures that allow steel strips with a thickness to cast between about 5 and about 40 mm directly in the continuous casting process.
  • this object is achieved by two forming the cast strand, coolable broadside plates in vertical position with a coolable, bottom-side End plate and at least one of the shaping cavity final side plate and one from above into the cavity of the mold protruding immersion pouring tube as well as with one of the side plates arranged outlet gap for the cast strand and means to this sideways pull out of the mold.
  • Figure 1 shows that the mold cavity 5 of the mold 10 by two cooled broad side plates 1, 1 ', a cooled end plate 2 and an optionally heated side plate 3 is formed.
  • the broad sides 1, 1 'and the end plate 2 consist of one of the known mold materials such as Copper with alloy additives such as Silver, chrome, zirconium, beryllium.
  • the Side plate 3 consists of a material with a comparatively low thermal conductivity, such as. Ceramics.
  • the broad side plates 1, 1 ' have in the upper lateral, facing the side plate 3 a funnel-shaped extension 18 on.
  • This extension 18 can both by in any contour vertical and horizontal direction can be specified.
  • the outer contour lines 8, 9 of the extension 18 can have any course.
  • the Expansion can extend to the end of the mold, which is the exit gap 12 forms.
  • the continuous casting process with the mold according to the invention provides that the Melt over that arranged at the starting point 15 perpendicular to the casting direction Immersion pouring tube 4 is inserted into the mold.
  • Immersion pouring tube 4 is inserted into the mold.
  • On the broad side walls 1, 1 'and on the end plate 2 forms a due to the high heat dissipation Strand shell, which determines the shape of the casting strand at the mold outlet 12.
  • This strand is laterally removed from the mold by a suitable device 13, e.g. a pair of driven rollers pulled out.
  • the width of the casting strand is determined by the position of the bath level and in it Height adjustable position of the end plate 2 determined. Height and slope of the End plate 2 can be changed both before and during the casting process can be set.
  • the broad side plates 1, 1 Due to the funnel-shaped expansion 18 of the cavity 5, the broad side plates 1, 1 'over the height a variable length of the horizontal inner contour on. For a fault-free formation of the strand shell, one must over the Height of the mold ensures constant length of the horizontal inner contour his.
  • the essential feature of the invention is therefore the inclination of the edges 6, 6 'in the casting direction in at least one height region of the mold, as shown in FIG. 2 is shown. The inclination can vary both over the height of the mold be unchangeable as well.
  • the end plate 2 In order to adapt to the shrinkage of the casting strand, the end plate 2 have a taper from the starting point 15 in the casting direction 16. At the same The vertical contours of the broad sides 1, 1 'from the vertical can be used for this purpose be inclined.
  • a lubricant preferably Mineral oil, graphite or wax or a mixture of these constantly on this edge fed. This is done through holes 7 in the broad side plates 1, 1 'and / or in the side plate 3.
  • the Bath level 17 is given a conventional mold powder at regular intervals become.
  • the slag that forms is with the strand in the casting direction transported and can be outside the mold by an air or water jet to be blown away.
  • this is before and optionally also heated during the casting process, e.g. electrical or by a gas or oil powered burner.
  • the side plate 3 can consist of different layers or areas with different Composition and different properties exist.
  • An embodiment of the invention according to FIG. 2 provides that above the bathroom mirror at least one further narrow side part 14 is placed, that for clamping the broadside plates 1, 1 'is used.
  • the length of this as a component a narrow side parts 14 used is less than that End plate 2. Since the narrow side parts 14 do not come into contact with the melt, The invention provides that these are preferably not provided with cooling be made of an inexpensive material with sufficient strength are made.
