Definitions

  • the invention relates to a mold for the continuous casting of steel strip or thin slabs with cooled broad side walls and narrow side walls, the wide side walls forming a funnel-shaped pouring area, which is reduced to the narrow side walls and in the casting direction to the format of the cast strip and on each broad side wall the curvature of the pouring area by lateral Circular arcs and central arcs connected to them at tangent points are determined, the radii of which gradually increase with their distance from the upper edge of the mold.
  • the curvature of the broad side walls forming the pouring area is designed in the form of an arc of a circle such that both the radii of the lateral arcs and the radii of the central arcs gradually increase in the direction of the strand.
  • the strand shell that forms immediately below the casting level is continuously deformed up to the end of the pouring area due to the change in radius of the arcs. The deformation increases the friction between the strand shell and the broad side wall and thus the tensile stress on the strand shell.
  • EP-B1 02 68 910 discloses a mold with an enlarged pouring area, a first section of the pouring area being used to reduce the strain on the strand shell the broad side wall is parallel-walled, resulting in opposite deformations.
  • the object of the invention is to provide a mold of the type specified, the curvature of the broad side walls determined by an arc being designed in such a way that friction and wear on the broad side walls are reduced and the tensile and bending stress on the strand shell is reduced in such a way that the operational reliability of the casting process is increased and a flawless steel strip is produced.
  • the invention is based on the idea of creating deformation-free arch areas on the broad side walls.
  • the radii of the lateral arcs from the upper mold edge are constant in a portion of the pouring area which extends at least 100 mm down from the upper mold edge.
  • a further enlargement of the deformation-free curvature areas is achieved in that the radii of the lateral arcs are the same over the entire height of the pouring area.
  • a steel strip casting mold consists of two broad side walls 1, 2 and two narrow side walls 3, 4 arranged laterally between the broad side walls 1, 2.
  • the wide side walls 1, 2 each form a pouring area 5 through an upper bulge, which leads to the narrow side walls 3 , 4 and in the casting direction to the thickness of the cast steel strip 6 is reduced.
  • the shape of the pouring area 5 is determined by lateral arches and middle arches, the radii of curvature R s and R m of which increase uniformly in the casting direction.
  • the tangent points T of successive arcs R s and R m form straight lines 7. Due to the successive enlargement of the radii R s and R m , the strand shell of the cast steel strip 6 is deformed on the entire surface of the pouring area 5.
  • FIG 3 shows a side of a pouring area 8 shaped according to the invention with lateral and inner arches in the levels I, II, III.
  • the radii R mI , R mII , R mIII of the middle arcs are evenly larger from top to bottom.
  • the radii R sI and R sII of the lateral arches remain the same up to level II and increase evenly from level II to the end of the pouring area 8. This results in a lateral displacement of the tangent points T I , T II up to level II .
  • kinked lines 9 are shown as the geometric location of the tangent points T I , T II , T III . In this way, a zone 10 is formed in which the strand shell of the cast steel strip 6 is advantageously not deformed.
  • Fig. 5 shows a side of an alternatively shaped pouring area 11 with side and middle arches in the levels IV, V, VI.
  • the radii R mIV , R mV , R mVI of the middle arches are evenly enlarged from top to bottom.
  • the radii R sIV , R sV , R sVI of the side arches are the same across all levels IV, V, VI. This results in a lateral displacement of the tangent points T IV , T V , T VI over the entire height of the pouring area 11.
  • lines 12 are shown as geometric locations of the tangent points T IV , T V T VI .
  • the strand shell of the cast steel strip 6 is advantageously not deformed.
