Definitions

  • the present invention relates to an oscillation device for oscillating a continuous casting mold in the oscillation direction.
  • Oscillation devices for continuous casting molds are known in principle to the person skilled in the art.
  • the mold is oscillated by means of an oscillation device with respect to a stationary support structure, so that adherence of the casting strand of liquid metal, preferably of steel, formed in the mold to the mold is prevented.
  • an oscillation device for oscillation of a continuous casting mold in the oscillation direction comprising a stationary support structure for supporting the continuous casting mold and a first pair of springs, consisting of an annular first spring and an annular second spring, wherein each of the first spring and the second spring the Continuous casting mold surrounds, and the second spring one having first distance in the direction of oscillation to the first spring.
  • the object of the invention is to overcome the disadvantages of the prior art and to provide an oscillation device for oscillation of a continuous casting mold, with which an exact guidance of the mold can be realized even with a very compact design of the oscillation device.
  • a device wherein the first spring is attached to the continuous casting mold in a first quadrant and to the support structure in a third quadrant, and the other quadrants are free, and wherein the second spring is secured in a first quadrant to the support structure and in a third quadrant to the continuous casting mold, and the other quadrants are free.
  • the continuous casting mold is supported by at least one first pair of springs, consisting of a first and a second annular spring, with respect to the stationary support structure, wherein the mold is enclosed in each case by the first spring and the second spring.
  • the first spring is attached to the continuous casting mold in a first quadrant and a third quadrant to the support structure, the other quadrant of the first spring are free.
  • the second spring is arranged rotated by 180 ° with respect to the first spring, so that the second spring is attached in a first quadrant to the support structure and in a third quadrant to the continuous casting mold, the other quadrants are free again.
  • this construction has a high rigidity transversely to the direction of oscillation, so that a high guiding accuracy of the mold is achieved.
  • an annular spring does not have to be round in this case. Circular or oval springs are advantageous for round or n-sided casting formats, but other shapes would be conceivable.
  • the mounts of the first spring on the continuous casting mold and the support structure are diametrically opposed to each other; the same applies to the second spring.
  • the second spring is aligned parallel to the first spring.
  • the first spring and the second spring lie on radius rays which have a common center, preferably the center of the installation or the center of the radius of curvature of the mold.
  • the oscillation device has a second pair of springs, consisting of an annular third spring and an annular fourth spring, wherein in each case the third spring and the fourth Spring surrounds the continuous casting mold at least partially, and the first spring pair has a second distance to the second spring pair, wherein the third spring is secured to the continuous casting mold in a first quadrant and to the support structure in a third quadrant, and the other quadrants are free, wherein the fourth spring is secured in a first quadrant to the support structure and in a third quadrant to the continuous casting mold, and the other quadrants are free.
  • the oscillation device has a second pair of springs, consisting of an annular third spring and an annular fourth spring, wherein each of the third spring and the fourth spring at least partially surrounds the continuous casting mold, and the first pair of springs to the second pair of springs has a second distance, wherein the third spring is secured in a first quadrant to the support structure and in a third quadrant to the continuous casting mold, and the other quadrants are free, and wherein the fourth spring is secured in a first quadrant to the continuous casting mold and in a third quadrant to the support structure, and the other quadrants are free.
  • the latter embodiment has a particularly high guide accuracy transversely to the direction of oscillation.
  • an oscillation drive for initiating or maintaining the oscillation between the first and the second spring pair is arranged.
  • an electromagnetic stirring device in the casting direction below the first or second pair of springs.
  • a particularly compact design can be achieved if the mold is designed for casting billets or billet cross-sections.
  • first and the second spring have a closed cross-section in a normal plane to the oscillation direction.
  • at least one of the group of first spring and second spring has an open cross-section, e.g. as a spring slotted transversely to the oscillation device, in a normal plane to the oscillation direction.
  • the second distance is greater than the first distance, preferably that the second distance is 5 to 20 times the first distance.
  • the bending stresses in the springs can be kept particularly low, if at least one of the group first spring, second spring, third spring and fourth spring, laminated lamellar structure.
  • a lamellar layered structure is understood when a spring of several, arranged one above the other in the direction of oscillation, a distance from one another, individual springs is formed.
  • first embodiment of an oscillation device for oscillation of the continuous casting mold 1 in the direction of oscillation 2 has a first pair of springs 3, consisting of a first spring 4 and a second spring 5, and a second pair of springs 7, consisting of a third spring 8 and a fourth spring 9, on , All springs 4, 5, 8, 9 are each formed annularly, each enclosing the mold 1, and are arranged in a normal plane to the oscillation direction 2.
  • the first spring 4 has the second spring 5 and the third spring 8 to the fourth spring 9 in each case the distance 6 to each other.
  • the first spring 4 is connected in a first quadrant by means of a first spring holder 11 with the continuous casting mold and diametrically opposite, in a third quadrant by means of a second spring holder 12 with the support structure 14; the other quadrants are free.
  • the second spring 5, which is arranged below and parallel to the first spring 4 is in a first quadrant with the support structure and attached to the continuous casting mold in a third quadrant; the other quadrants are free again.
  • a second spring pair 7 is arranged at a second distance 10, wherein the second distance is 10 times the first distance 6, which consists of a third spring 8 and a fourth spring 9.
  • the third spring 8 as well as the first spring 4
  • the fourth spring 9 as well as the second spring 5 with the mold 1 and the support structure is connected.
  • FIGS. 6 to 11 show a second embodiment of an oscillation device for oscillation of the continuous casting mold 1, which has a first spring pair 3, a second pair of springs 7 and each offset at a third distance 15, a third pair of springs and a fourth pair of springs.
  • the first pair of springs 3 consists of a first spring 4, which is connected via a first spring holder 11 with the continuous casting mold 1 and diametrically opposite via a second spring holder 12 with the support structure 14.
  • the second spring 5 is arranged rotated by 180 ° with respect to the first spring 4.
  • the second spring pair 7 consists of a third spring 8 and a fourth spring 9, wherein the third spring 8 is arranged rotated by 90 ° relative to the first spring.
  • the fourth spring 9 is arranged rotated by 180 ° with respect to the third spring 8. Below the first and second spring pair 3, 7, a third and fourth spring pair is arranged at a distance 15, wherein the arrangement of the third spring pair corresponds to the first spring pair and the arrangement of the fourth spring pair to the second spring pair.
  • FIG. 12 shows an alternative to Fig. 3 with a slotted first spring 4.
  • the annular first Spring 4 in the region of the attachment to the support structure 14 executed radially slotted, wherein the second spring holder is also formed in two parts, as a left spring holder 12a and as a right spring holder 12b.
  • the rigidity of the oscillator in the oscillation direction can be further reduced.
  • the execution of open cross sections in the springs by no means limited to the first spring 4, but each spring could be formed, for example, slotted.
