Definitions

  • the invention relates to a continuous casting device, in particular for the continuous casting of steel, with a mold support device and a mold that is oscillating with respect to said mold, wherein the mold is supported on the mold support device via guide elements extending approximately transversely to the oscillation direction and forces in the elastic region, wherein the guide elements are arranged approximately parallel to one another and in the oscillation direction at a distance one above the other, wherein the guide elements are arranged approximately parallel to each other and in the oscillation direction at a distance one above the other and wherein each guide member is attached on the one hand to the mold support means and on the other hand to the mold, wherein at a A pair of adjacently arranged guide elements respectively the attachment of a first guide element to the mold and the attachment of a second guide element to the mold support means in we are arranged one above the other, wherein at least a first guide element extending from the mold support means to the mold in a first direction and at least a second guide member extending from the mold support means to the mold in a direction opposite to the first
  • a continuous casting device of this kind is known from US 5 219 029 A known. From the DE 22 48 066 A1 a continuous casting is known in which the mold is guided laterally over two parallel to each other and one above the other arranged spring assemblies, which are formed by band springs. The oscillation is accomplished by a hydraulic cylinder, which acts on the one hand on the scaffold and on the other hand on a console of the mold.
  • the two spring assemblies which are each arranged on a Kokillenseite and are firmly clamped on the one hand on the scaffold and on the other hand on the mold, in this case have to absorb the executives, ie they are charged to train or pressure. You must be dimensioned because of the pressure load on buckling, resulting in a large thickness of the spring assemblies, namely a much greater thickness than is required for the maximum tensile forces occurring.
  • a strand guide for a continuous casting mold is known in which the leadership of the mold is accomplished by means of a leaf spring, the both ends in a spring carrier is clamped bridge-like and wherein the leaf spring engages the center of the leaf spring.
  • a guide device requires a very large amount of space in the direction of the leaf spring axis.
  • Such a guide can only be provided where the side of the mold enough space is available. This is usually not the case with bloom or billet plants, so that no use can be made of this type of guide for such plants.
  • the invention aims to avoid these disadvantages and difficulties and has set itself the task of creating a continuous casting of the type described above, which requires only a small space requirement and low driving forces for the oscillation drive in addition to a high guidance accuracy for the mold.
  • the space requirement should be so low that an application for Bloom and stick plants in a simple manner possible.
  • a tilt-proof support of the mold should be realized.
  • At least one to the mold support means and the mold support means each at least one to the mold extending support arm 5 are provided on the mold, which are arranged approximately overlapping each other and seen in the oscillation direction approximately overlapping, and extends at least one guide member is fixed from the end portion of the one support arm to the end portion of the other support arm and is itself fixed thereto.
  • the continuous casting device is advantageously characterized in that a first Guiding element and a second guide element arranged approximately parallel thereto are provided at an angle to a further first guide element and the second guide element arranged approximately parallel thereto, wherein the longitudinal axes of the guide elements are advantageously oriented approximately to radius rays of the arc defined by the arcuate mold for a curved mold.
  • the first and the second guide element, each with a support arm 5 form a structural unit.
  • This embodiment allows a simple construction and a simple installation of the guide elements or a simple replacement of the same.
  • the guide elements can be constructively provided in a particularly simple manner where they can be accommodated most easily in terms of space.
  • the guide elements of spring bands in particular each formed by spring band packages, but it is also possible to use ropes, rods and / or membranes as guide elements.
  • the guide members are made of steel or plastic, e.g. Carbon fiber or glass fiber, formed.
  • Fig. 1 a section through a billet mold and Fig. 2 To illustrate a plan of this mold.
  • the Fig. 3 and 4 show embodiments for Bogenkokillen also in section.
  • the Fig. 5, 6 and FIGS. 7, 8 show further embodiments of a continuous casting device not according to the invention, wherein the Fig. 5 and 7 Cuts analogous to Fig. 1 and the Fig. 6 and 8th Partial sections according to the lines VI / VI and VIII / VIII of Fig. 5 or 7 illustrate.
