Definitions

  • the invention relates to a method and a device for the continuous casting of slabs or blocks in a continuous casting installation with a soft reduction path, which can be adjusted individually or as a segment by means of hydraulic cylinders against one another and can be infinitely adjusted with respect to one another by means of spindles.
  • Continuous casting plants in which a plurality of opposing pairs of rollers are combined into one unit in a strand guide segment, have become known from GB-A-1 166 044 and EP-A-0 194 656.
  • the strand guide segments are assigned several hydraulic cylinders with which, for example, the rollers above the strand can be adjusted against the lower rollers.
  • fine adjustments can be made, namely in the event of deviations from the desired thickness of the cast strand.
  • the slabs or blocks produced in such continuous casting plants serve as the starting material for rolling mill products, such as in particular slabs or thin slabs for the production of sheets or strips.
  • a thickness reduction between 0.5 mm per meter and 3 mm per meter is carried out in a soft reduction section of the continuous casting plant in the area of final solidification.
  • the width of the mouth is adjusted according to the shrinking behavior of the strand over the length of the machine.
  • the pairs of rolls, individually or combined into segments, are adjusted more closely beyond the shrinking behavior of the strand in order to (The page 2 of the original documents remains unchanged.)
  • Truss and roll deflections e.g. through the use of split continuous casters, can be kept small across the width of the strand.
  • the upper yoke is inclined from the inlet towards the outlet so that there is a smaller mouth width on the outlet side than on the inlet side.
  • the soft reduction no longer leads to an improvement in the internal structure of the cast strand if the strand has already solidified before entering the soft reduction path or if it has not solidified at the end of the soft reduction path.
  • the strand should therefore run into this stretch with a targeted reduction in thickness with a residual sump and be solidified at the end of the soft reduction stretch.
  • the invention has for its object to provide a method and an apparatus that with simple means a dynamic distance or mouth width adjustment even during the casting operation, i.e. enable under load, especially in adaptation to the changing position of the soft reduction section due to changing casting parameters.
  • This object is achieved in that the contact force is reduced during the casting and the spindles are moved to a desired width-reduced dimension.
  • the desired jaw width can thus be adjusted continuously using the reduced-load spindles.
  • pressure transducers which enable continuous force measurement, can be arranged between the spindles in the upper part of the segment and the lower part of the segment. Due to this astonishingly simple measure of pressure relief, an essentially load-free, inexpensive and reliable adjustment of the spindles inside and outside the cooling chamber of the continuous casting plant can be achieved.
  • the length of the soft reduction section and the reduction in thickness can be adapted to the casting speed, ie at a lower casting speed the length of the soft reduction section is shortened and the thickness decrease in mm per meter; at higher speeds, however, the length of the soft reduction section is increased.
  • Thickness reduction can be set differently within the soft reduction range and thus support the improvement of the internal quality.
  • the hydraulic pressure of the adjusting cylinders can be reduced during casting so that the force acting on the spindle can only be a fraction of the operating force - the maximum force that occurs during operation up to 100 t, if, for example the strand is solidified - corresponds, for example, to just 2 to 3 t, so that an opening width adjustment is possible in a simple manner, for which only a low drive power is required.
  • an excess of force can be determined and, from the forces which occur, it can be concluded where the strand still has a residual sump or where it has solidified and thus determine the position of the soft reduction path. This enables rapid process optimization in the sense that the exact position of the soft reduction section and the decrease in thickness can be determined as a function of essentially the casting speed, the secondary cooling and the steel quality.
  • the spindles can be based on a load cell according to a proposal of the invention. These show both the excess force from the segment or roller locking force that enables the determination of the soft reduction path and the relieved hydraulic pressure, which enables the spindles to be moved with reduced load during casting.
  • the spindles can be driven against a hydraulic stop which is subjected to a force which exceeds the locking or setting force is.
  • the hydraulics need to be depressurized to adjust the rollers to a new internal width dimension or a new clearance dimension, and the spindles can then be moved to the new dimension with reduced load.
  • a plunger is arranged between a spindle and a support of the lower yoke, which has a fixed stop in its cylinder space.
  • the plungers can be driven against their fixed stops with an excess of force, which support the spindles with a pressure exceeding the starting pressure.
  • the plungers are pressurized again until they come into contact with the pistons against the fixed stops; in this position the rollers then take the desired distance from each other.
  • rollers 2 In a continuous caster, not shown, for casting slabs or blocks, numerous rollers 2, either arranged individually or in strand guide segments 1, form a guide, which may have a thickness reduction on an extruded strand 3 (see FIG. 3).
  • the rollers 2 can be adjusted to one another to the desired thickness 4 by means of hydraulic cylinders 5, the cylinder tubes 6 of which are fastened to the lower yoke 7 and the piston rods 8 of which engage the upper yoke 9 of the strand guide segment 1, as is shown in FIGS. 1 and 2.
  • Each at the inlet and outlet 11 or 12 (see FIG. 3) of the strand guide segment 1 are paired, adjustable by a motor 13, a gear 14 and drive shafts 15 (see FIG.
  • adjustable or adjusting spindles 16 which are based on pressure transducers 17 in the embodiment according to FIG. 1 and on plungers 18 in the embodiment according to FIG. 2, which are arranged on a support 19 of the lower yoke 7.
  • the cylinder housings 21 of the plungers 18 have a fixed stop 23 in their cylinder space 22, against which the plungers 24 bear.
  • the thus reduced-load adjustment of the pressure spindles 16 makes it possible to adapt the rolls to be moved closer to one another in this zone than required as a result of the shrinkage of the strand, even during operation, to changing casting parameters in a continuous casting installation.
  • the soft reduction section is located where there is still a residual sump 27 in the section 3, but after the exit from the soft reduction section the section is completely solidified (cf. FIG. 3); it shifts - in relation to the strand running direction - with changing casting parameters such as, in particular, different casting speeds up or down.
  • the forces are measured continuously by means of the pressure load cells 17 and can be inferred from measured values which differ from one another, where the strand 3 still has a residual sump 27 or where it has already solidified.
  • the upper yoke 9 is inclined towards the outlet 12 on the basis of the measured values, so that the mouth width 25 is greater at the inlet 11 than at the outlet 12 (cf. Mouth width 26 in Fig. 3) results.
  • the wedge can be adjusted in accordance with the residual sump 27 so that the strand 3 within the solidification section is as short as possible before the solidification point - cf. in Fig. 3 the sump tip numbered 28 - a deformation with a decrease in thickness of e.g. 0.5 mm to 3 mm per meter.
  • the strand guide rollers 2 - regardless of whether they can be adjusted individually or as a segment - can always be adjusted to changing casting parameters and / or one correspondingly Adapt the changing position of the sump tip 28.
  • position adjusters 29 are also assigned to the spindle adjustments, which - starting from a calibration value which can be e.g. can be reached by lowering the upper yoke 9 to fixed stops - allow a more or less wide opening at the inlet and outlet 11, 12.
