Definitions

  • the invention relates to a liquid-cooled, width-adjustable plate mold for the continuous casting of steel strands in slab format, in particular with a slab thickness of less than 100 mm.
  • molds are usually used, the free cross-sectional area at the mold exit of which corresponds to the desired strand format.
  • DE 35 01 422 C2 also includes a mold of the prior art, the narrow walls of which can be adjusted to different strand dimensions and the pouring opening has an oval cross-sectional area. At the outlet end, the mold tapers in such a way that the slab broad sides are formed with parallel walls, while the narrow side walls diverge from the pouring side to the pouring side. but keep their concave shape.
  • a mold is also known from EP 0 249 146 or US Pat. No. 4,716,955.
  • molds are known, with flat surfaces of the narrow sides of the mold and broad sides that bulge outwards over the entire height of the mold.
  • the present invention has for its object to improve the cooling conditions within the continuous casting mold and to avoid blocking the movement of the strand in the width direction when the strand passes through the mold, so that the risk of longitudinal cracks and breakthroughs is largely excluded.
  • Part of the invention is that the reduction in the apex height can be done both linearly and after an e-function.
  • the crowning provided according to the invention can also differ from the circular shape in a polygon or from the combination of Polygonal trains and floor elements. Overall, it is provided that at the bottom of the mold, that is to say at the end of the strand exit, there is still the optimum crowning of, for example, 1 mm per side for a rolling process. Accordingly, the following roller strand guide is designed in accordance with the crowning of the strand. This results in the advantage, among other things, that all rolls of the same diameter can be freely converted in their position and no deformation work with regard to changing the crowning has to be carried out.
  • the broad side plates 1 are processed in the area 3 'in such a way that the surface enclosed by the broad sides in plan view, starting from side lines of the inscribed rectangle, form an isosceles trapezoid in such a way that the larger base line of the trapezoid coincides with the side lines of the inscribed rectangle.
  • the base line of the trapezoid is 0.4 mm longer than the opposite side.
  • the contact pressure of the broad side plates on the narrow side plates is first reduced when the width is adjusted, the narrow side plates are then moved and then the broad side plates are then pressed again.
  • the described design of the broadside plates 1 can be used with straight and circular molds and also with curved molds with several different radii of curvature, as shown in FIG. 3 and designated R1-R4.
  • a mold is shown, the pouring side of a straight section 6 with a subsequent arcuate part consists.
  • the immersion spout 7 which is elongate in cross section, for supplying the melt.
  • the broad side plates 1 are cooled by means of water which is passed through channels 8 in the rear of the shaping wall consisting of copper.
  • the copper walls are fastened in the usual way to a plate, not shown, which at the same time covers the channels, via bolts which engage in recesses 9.
  • the cooling channels 8 have a depth, at least in the upper mold half, such that the distance of the channel base 8 ', seen in plan view, increases from the mold center 10 to the narrow side walls 2 in relation to the surface of the broad side plate 1 facing the melt.
  • the mold consists of three areas with different crown heights 13 of the arc.
  • the area 6, here also designated L1 corresponds to that as described in FIG. 5.
  • the apex height 13 decreases linearly to an amount 14 which corresponds to the mold exit 5.
  • the lower mold section 12 thus has a constant apex height 13.
