Definitions

  • Another and more specific object of the present invention relates to a new and improved construction of apparatus which allows oscillating or reciprocating a continuous casing mold by means of short levers without having to take into account any appreciable disadvantages with respect to the quality of the cast product.
  • the invention contemplates that the paths of movement of the hinges or pivot points at the mold are curved opposite to the axis of the path of travel of the strand.
  • intersection points are located at the end or terminal points of the oscillation path of the mold along a tangent taken with respect to the axis of the strand path of travel and the point at the lower end point at the same time constitutes the contact point of the tangent with the strand path of travel axis.
  • the deviations of the paths of movement of the hinges or pivot points at the mold from the strand axis to both sides of such strand axis are uniformly divided. Consequently, the relative error, that is to say, the deviation from the desired axis of the path of travel of the strand, can be reduced by one-half.
  • FIG. 1 is a partial sectional view through the uppermost portion of a continuous casting installation or plant having a curved axis of the strand path of travel, and also depicting the mold, the oscillation mechanism and the uppermost guide region for the strand;
  • FIG. 2 schematically illustrates the course of movement for the point of intersection of the moldingand guide hollow cavity axis with the lower end surface of such oscillating moldingand guide hollow cavity
  • FIG. 3 illustrates a modified form of guide mechanism with a lever replaced by a guide track.
  • FIG. 1 there will be recognized a continuous casting mold arrangement which comprises the open-end continuous casting mold l and in certain cases also an extension 1 thereof.
  • This mold l encloses a hollow mold cavity or compartment 3 which at its end region also can constitute a hollow guide cavity or compartment.
  • Means defining a first guide zone 2 is connected with the mold 3, this guide zone-defining means 2 enclosing a hollow guide compartment 4 and following which there is arranged a strand guide arrangement or mechanism, the uppermost segment of which has been conveniently designated by reference character 22.
  • the mold l, the means defining the first guide zone 2 and the strand guide mechanism 22 are components of a curved strand path of travel with associated strand path of travel axis 15.
  • Two guide levers or links 8 and 9 are coupled for instance with the mold l and its extension 1 via the hinges or pivot points 11 and 12. Of course, if the mold l is of the type not having a mold extension, these two levers can be directly coupled with the mold itself.
  • These guide levers 8 and 9 are also mounted at the bearing or support locations 10.
  • bearing locations 10 are secured to a stationary frame 7, and wherein at such stationary frame 7 there is also arranged in known manner an oscillating drive as well as transmission devices which, however, for the purpose of preserving clarity in illustration have not been particularly shown, especially since such constitute standard structure in this particular art. It is of course possible where necessary to duplicate the arrangement of such links or levers at the opposite side of the mold, so that the latter is straddled by two pairs of such levers.
  • the levers or links 8 and 9 coupled with the mold 1 at the hinge or pivot points 11 and 12 oscillate about the bearing or support locations 10.
  • Both of the bearing locations 10, the levers 8 and 9, and both of the hinge points 11 and 12 as well as the continuous casting mold arrangement thereby form a four-element hinge or linkage mechanism.
  • the ends of the levers 8 and 9 which are connected with the mold arrangement at the points 11 and 12 move along circular paths of travel 17 and I8 and specifically having the radii 34 and 35.
  • the circular paths of travel 17 and 18 are curved opposite to the axis of the path of travel of the strand.
  • levers or links 8 and 9 are arranged in pairs in order to be able to also laterally guide the mold I; it is however also possible to employ only one respective lever 8 and 9 and to support the mold l by means of gliding surfaces or rollers against deviations perpendicular to the levers 8 and 9.
  • the mold 1 and the means defining the first guide zone 2 which forms the oscillating region do not exceed a certain permissible deviation from the strand path of travel axis 15. This deviation amounts up to about 0.2 mm., wherein the maximum deviation is dependent upon the metallurgical quality of the cast steel. The deviation must be least at the lowermost point of the oscillatory movement, since at that location the distance between an imaginary end surface 26 of the oscillating region and the next fixed guide portion of the strand 3 guide segment 22 is also least.
  • the lower end surface of the oscillating region coincides with the end surface of the hollow mold cavity 3. If, however, the guide element 2 arranged following the mold 1 is likewise oscillated, then, the oscillatory region first terminates at a surface of the hollow guide compartment 4 and which is disposed perpendicular to the strand path of travel axis 15, and which surface directly merges at the lowermost oscillating guide means 5.
  • the end surface 26 has shifted by an amount corresponding to the oscillation stroke into the position depicted by reference character 26. If the points 28 and 28' are located at tha tangent 32, then there is realized a particularly uniform transition of the oscillating components with respect to the stationary strand guide.
  • the displacement of the point 28 into the position 28 occurs along the periphery of a circular are 18 having the radius 35, wherein the are 18 is curved opposite to the arc of the strand path of travel axis 15 having the radius 33.
  • the radii 35 and 33 and the associated centers are chosen such that the point 28 is deflected uniformly to both sides of the strand path of travel axis 15, so that the deviations 38 or 39 from the strand path of travel axis 15 are reduced by one-half.
  • the entire deviation or deflection is located at the same side of the strand path of travel axis 15.
  • said hinge mechanism further including hinges provided for said frame and two guide levers providing connection element means between the hinges of the mold arrangement and the hinges of the frame, both of said guide levers extending in substantial parallelism with respect to one another.
  • said hinge mechanism further including a first and second connection element provided between said mold arrangement and the frame, one said connection element being formed by a guide lever and the other connection element being formed by a guide track.
  • the cast strand has an inner curved surface and an outer curved surface, the curved axis of the path of travel of the cast strand having its radius of curvature located at the side of the inner curved surface of the cast strand, and said radii of curvature of the pivot points being located at the side of the outer curved surface of the cast strand.
  • An apparatus for guiding an oscillatory continuous casting mold arrangement of a continuous casting installation having a curved axis of the path of travel of the cast strand comprising a hinge mechanism composed of a plurality of elements, one of said elements being formed by said mold arrangement, said mold arrangement being provided with hinge means at said mold arrangement, another of said elements serving as a frame constituting a part of the structure of the continuous casting installation, said hinge means of said mold arrangement having a pivot point located at the mold arrangement, said pivot point moving through a path of travel possessing a curvature which is opposite to the curvature of the curved axis of the path of travel of the strand.
