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.
