Definitions
- the invention relates to a continuous casting device with a continuous casting mold Casting liquid metals, especially steel materials, with billets, Block, Vorblock-, Shin-Vorprofil-, Rund- or polygon strand format, one continuous, from the mold inlet to the mold outlet of the Shrinkage superimposed guide profile is cast outside the mold is deformed to a solidified end profile.
- DE 43 18 105 A1 discloses a mold for the continuous casting of metal, in particular of steel in billet and billet cross-sections known, with regularly distributed Cross-sectional enlargements in the form of bulges.
- the degree of bulges shrinks at least along a partial length in the direction of the strand such that the strand cross-sectional shape deforms as it passes through the partial length.
- this measure only aims at using water jackets as a tubular body to be able to use essentially parallel walls.
- DE 44 03 050 C1 discloses a continuous casting mold for guiding strands, however known with regard to slab and thin slab formats, with broad side plates and narrow side plates, the broad side plates being concave and the concavity extends up to and including the mold outlet opening and the crowning of the strand in the strand guide is withdrawn to a rectangular format becomes.
- the crowning extends over the full length between the Narrow side panels.
- such a design is based on slab and thin slab formats limited and the withdrawal of the crowning already in the Strand guidance is significantly dependent on the formation of the strand shell and the forces that can be applied in the strand guide.
- the invention is based, for so-called long products already within the task to create a guide for the continuous casting mold in combination with increasing quality requirements, that affect the core zones of the casting strand.
- the task is achieved by means of the continuous casting device described at the beginning solved with continuous casting mold according to the invention in that in the continuous casting mold two opposite sides are flat in cross section and approximately run parallel to each other and at least two other, opposite in cross section Sides are concave to the respective side edges, only one low symmetrical drop from the middle of the page to the respective side edge is that there is a concave surface on the mold outlet on the Support frame rolls lies and that the non-flat sides with or without liquid Swamp by means of deformation rollers in the soft reduction or hard reduction area are flat deformable.
- the first advantage is stable management of the long product through parallel surfaces, an even roller contact and a required Symmetrical position of the casting strand in the continuous casting mold and in the support roller frame.
- the Quality improvement can be achieved through the technological process of pressing together the strand shells in the area of final solidification (soft reduction) and thus over a due to the difference in density of the solid and the liquid phase Volume decrease and return to the flat shape can be achieved.
- a Another improvement in quality is the compression of the casting strand after complete solidification (hard reduction), in which compensated for the imperfections caused by the solidification process across the strand cross-section become.
- the concave, opposite Areas are formed by an arc with a large radius.
- An alternative solution based on the same continuous casting device cited at the beginning, according to the invention is that two in the continuous casting mold opposite sides are flat in cross section and approximately parallel to each other, that at least two others opposite in cross section Sides from the axis of symmetry of the center of the page to the outer Areas run flat and gently offset each to the side edge Form transition in the sense of a medium increase, the transition being a transition function follows and that the mean cant with or without liquid sump Formed flat using deformation rollers in the soft reduction or hard reduction area becomes.
- One embodiment provides for the gently stepped transition to appear in each case Curves is formed and that even the side edges with a smooth transition are provided.
- the advantage is later easier deformability in combination with a cheap production of the mold plates or used mold tubes.
- the continuous casting device consists in that in the continuous casting mold two opposite sides in cross section are flat and parallel run to each other and at least two others opposite in cross section flat sides in the corner areas (preferably square or rectangular ones or oval) have recesses that also extend into the flat sides and form opposite increases and that the increases with or without liquid sump by means of deformation rollers in the soft reduction or hard reduction area are flat deformable.
- corner areas preferably square or rectangular ones or oval
- the continuous casting device has a continuous casting mold 1 with a mold length 1a on and is to the lower level at a height 2, in which the fill level 3 lies above the neutral mold axis.
- the bath level fill level 4 is on the same level height 2. From the fixed side 5a, the horizontal length 6 is measured in the direction point and the total system length 7 extends to the end of a driving and straightening area 8th.
- the support roller stand 9 following the continuous casting mold 1 is in the exemplary embodiment from a first segment 10, a subsequent second segment 11, composed of a third segment 12 and a fourth segment 13.
- a billet strand format 14 with a greatest strand thickness 15 is shown and has a difference in thickness 17 over a large radius 16, wherein from the mold inlet opening 18 to the mold outlet opening 19 under consideration the shrinkage creates a guide profile 20.
- the guide profile 20 allows a mold shape for increasing quality requirements.
- the sides 21a opposite in cross section 21 and 21b are flat and run largely parallel to one another.
- the two other sides 22a and 22b, which face each other, extend to the side edges 23 and 24, with only a slight symmetrical drop 25 from the side center 26, such as 2w. 3-4 mm, up to the respective side edge 23, 24 is specified.
- Fig. 3 are in the continuous casting mold 1 two opposite in cross section 21 Sides 21a, 21b are flat and parallel to each other. At least two others (with a polygonal strand format) in cross-section v21 opposite Sides 22a, 22b each extend from the axis of symmetry of the center of the page 26 in the outer areas 30, 31 still flat up to the side edges 23, 24, where a gently stepped transition 32 takes place and thereby against a medium increase 33 is achieved.
- the transition 32 follows a mathematical transition function.
- the smoothly offset transition 32 is formed from curves 34, the side edges also 23, 24 are provided with a soft transition 32.
