Definitions

  • the invention relates to an adjustable mold divider for installation in a slab mold with narrow side parts designed for lateral adjustment optionally casting multiple strands with variable strand widths, comprising a housing that can be installed in a stationary manner for the mold on its broad side plates and on both sides in the width direction of the mold adjustable adjustment with their End existing support plates and on these 'arranged narrow-sided Heat exchanger plates.
  • Continuous casting molds for steel usually have during casting or in Pouring breaks adjustable narrow sides, the adjustment ranges on the one hand mechanical conditions such as the control range of the drives or spatial limitations and forces to be absorbed, and on the other hand by procedural requirements, e.g. B. the relationship between subsequent melt times, Casting speed and casting width are limited.
  • Mold dividers are usually made with a fixed geometry of the spacing Mold plates from each other, and their taper. If mold divider they have to be adapted to very different format areas either designed to be interchangeable as a whole, or by installing adapters or Fitting pieces changed. Such adjustments can only be made outside the Casting process are carried out and thus increase the costs due to downtimes the plant considerably. In addition, the interpretation of the narrow side taper on the mold divider, as well as the positioning of the immersion spout only for a medium casting width. Both settings result from an increase the strand shell stress and deterioration of the flow pattern negative metallurgical consequences in the liquid strand content.
  • GB-A-1 308 592 relates to a mold divider for installation in a conventional slab mold with lateral adjustment Narrow side parts for the optional casting of several strands with changeable Strand widths, comprising a stationary mold between the broad side plates built-in housing with adjustable width on both sides of the mold Adjustment elements with support plates provided at their ends and on this arranged narrow-side heat exchanger plates.
  • the task of the present document is based on the document mentioned above
  • the invention consists in avoiding the disadvantages mentioned creating an adjustable mold divider.
  • This measure according to the invention is an adjustment of the casting width achieved during casting by making all four drive axles independent each have their own drive trains and motors.
  • This version also requires the largest installation space. Therefore can - while accepting reduced flexibility of the movement process - e.g. the two spindles arranged one above the other by a common side Motor driven and mechanical - e.g. through suitably staggered gear ratios - Coupled so that one required for the casting process Inclination, the so-called shrink taper of the heat exchanger plates depending remains unchanged from the adjustment path.
  • a staggered reduction can also be achieved with different spindle pitches can be achieved.
  • This arrangement has the positive consequence that the casting performance of the entire mold always remains constant, because during on one side the casting format is enlarged, on the opposite Page this is reduced accordingly. But it is also a coupling conceivable in which both sides shifted in opposite directions but to the same extent become.
  • the attachment of the adjustable mold divider between the broad side plates the mold can also be made off-center. This allows the area of the same time pourable formats can be further enlarged for a given installation space, even if spare parts are to be kept ready for each individual strand.
  • twin strands can also be combined in one large range with variable casting width without interruptions and with optimal sump flow with symmetrical inflow of the melt be shed.
  • Figure 1 shows an adjustable mold divider for installation in a conventional Slab mold 1 with for lateral adjustment during a casting process trained narrow side parts 6.
  • the mold divider comprises a relative for the mold 1, a housing that can be installed between the broad side plates 2 of the mold 3, which can be adjusted in pairs on both sides in the width direction of the mold 1
  • Adjusting elements 4 has support plates arranged at their ends 5 and with narrow-side heat exchanger plates 6 arranged thereon.
  • the adjusting members 4 of the mold divider are preferably spindles 9, which by means of the housing 3 integrable drive means 10 via gears and shafts 13 by external motors 11, 12 according to FIG. 4 or 5 electrically, hydraulically or can be driven pneumatically.
  • the support plates 5 are for absorbing vertical loads or forces in the upper Area, as shown in Figures 3 and 6, with transverse guide bolts 7 equipped, which are guided engaging in guide grooves 8 and in the mold broadside plates 2 are embedded in the upper area.
  • the reference numerals 9 indicate those that can be seen in the sectional illustration in FIG. 3 Designated spindles.
  • Figure 4 shows the oil supply means provided for a hydraulic drive of the spindles 14 for hydraulic oil, the connections for the spindle drives 9 in Figure 3 are shown.
  • Figure 6 shows in a section perpendicular to the support plate 5 and the arranged on it Heat exchanger plate 6 that to expand the adjustment range Spindles 9, the support plate 5 is excluded up to the heat exchanger plate 6, preferably the recesses for the prevention of sealing problems to the support plate 5 are designed as deep holes.
