Definitions
- the invention relates to a method and an apparatus for Continuous caster for the production of strands, their cross section is reduced during solidification.
- the strands are on high speed equipment generally with a solidification thickness between 18 and 450 mm and casting speeds up to a maximum of 12 m / min e.g. on plants for casting slabs, blooms and sticks with a square or round profile, one of which Reduction of the strand cross-section, preferably in the thickness direction made after it emerged from the mold during solidification becomes.
- So z. B a thin slab with a thickness of, for example, 65 to 40 mm in segment 0, which is located directly under the mold, reduced.
- This strand thickness reduction by 25 mm or 38.5% can qualitatively disadvantageous for certain steel grades sensitive to internal cracks his.
- the inner strand deformation can be caused by the Strand thickness reduction or also called casting rolls, for the trigger of internal cracks because of the critical deformation of the material liquid / solid on the inner strand shell, but also on the outer Strand shell is exceeded.
- This example is based on a 2 m long circular arc segment 0, which is none Introduces bending work or bending deformation into the strand shell.
- the forming speed the strand shell during casting rolling during solidification is 1.25 mm / s with a casting speed of 6 m / min. This value of the forming speed increases with a Casting speed increase to z. B. 10 m / min to 2.08 mm / s, where he becomes very critical.
- Such internal deformations caused solely by casting rolling are not just for the low-carbon steel grades that are relatively insensitive against internal deformations, but especially for sensitive steels such as micro-alloyed APX-80 grades critical.
- the deformation caused by the casting rolling can also with Vertical turning systems, usually in the segment under the mold at the same time there is a bending of the strand, still by the in the strand greatly increase the bending deformation, which increases the risk of exceeding it the critical deformation and thus the crack formation is further increased becomes.
- the above-mentioned knowledge and connections are forward-looking the invention has the object of procedural measures and simple device features the rate of deformation of the Specify strand cross-section reduction so that the critical deformation of the Stranges taking into account the casting speed and also the steel grade is not exceeded.
- the object is achieved according to the invention with a method for Continuous casting to produce strands, the cross section of which during solidification is reduced in such a way that in a particularly oscillating mold is poured and the strand cross section linear over a minimum length of Strand guidance immediately below the mold, the so-called casting rolls, is reduced and there is a further non-linear reduction in the cross-section of the strand, for example after the square-root function, the so-called "soft reduction", over the rest of the strand guide up to a maximum of just before the swamp tip.
- the features of the invention apply to all formats cast in the strand and also for all types of continuous casting plants and describe with the method to claim 1 and its subclaims as well as the device claim and its subclaims the invention.
- the thickness of the slab in the edge area at Mold exit z. B. is a minimum of 70 and a maximum of 160 mm is pulled.
- the reduction in strand thickness, normally between the top and bottom of a strand guide takes place, is according to the state of the art today under test conditions maximum 60%, here is a 50 mm thick slab reduced to approx. 20 mm over a roll gap length of approx. 200 mm, and under production conditions a maximum of 38.5%, here the Strand from 65 to 40 mm over the length of segment 0 of approx. 2 m, which is located below the mold, reduced. In both Cases there is a maximum pouring speed of 6 m / min.
- the description of the invention is based on an example Thin slab with a thickness of 100 mm at the mold outlet and a thickness of 80 mm after solidification.
- the invention now proposes one Type of distribution and implementation of strand thickness reduction during the solidification of the thin slab in the strand guide frame for the exemplary casting speeds of 6 and 10 m / min before.
- Tables 1 and 1.1 are the essential process and device data contrasted the invention with the prior art.
- Table 1 provides the data for casting speeds of 6 m / min and Table 1.1 for speeds of 10 m / min represents.
- FIGS 1 to 7 illustrate the invention in detail in comparison the state of the art.
- the pure melting phase or penetration zone is in the range of segment 0, in which a strand thickness reduction or casting rolling of 2 x 10 mm or 20 mm and no more in the following segments 1 to 13, - Description of the state of the art (Image 1) -, or of 2 x 5 mm or 10 mm, casting rolls, and another 10 mm in the following segments 1 to 13, "soft reduction", part of the invention (Photo 2).
- the reduction in strand thickness in the segment 0, the z. B. as pliers segment with two clamping devices, e.g. B. hydraulic cylinders (14) (Fig. 6), formed at the segment exit is linear over a length of 3 m; the reduction in the area of segments 1 - 13, but also across all segments, both linear and non-linear, i.e. for example following a square root.
- the strand thickness reduction of 10 mm in the segments 1-13 "soft reduction" - linear distribution.
- FIG. 4 schematically represents the situation of a Strands with a thickness in the mold of 100 mm and a solidification thickness of 80 mm for the casting speeds VG of 6 m / min, Figure 3, and of 10 m / min, Figure 4 compared.
- the strand thickness reduction is 6 m / min from Z. B. 10 mm in segment 0 and of the remaining 10 mm in the Segments 1 to 8, corresponding to the shorter solidification path, performed. So the lowest liquidus point (1.2) is at already about 1.8 m and the swamp tip (2.2) at about 18.12 m.
- the picture 4 in Figure 4 shows the situation of the strand like Figure 2 in Figure 1 at a casting speed of VG 10 m / min.
- FIG. 5 shows the effect of a distribution of the strand thickness reduction in segment 0 and in segments 1 to 13 in the sense of Invention ( Figure 6) using the example of a vertical bending machine, FIG. 6, compared to the prior art (FIG. 5), on the inner strand deformation, caused by the bending deformations and the strand thickness reduction, depending on the strand guide for the maximum casting speed of, for example, 10 m / min shown.
- Figure 5 represents the state of the art in Figure 5 the inner strand deformation depending on the strand guidance for the maximum casting speed (Vg-10) of 10, for example m / min compared to the boundary deformation (D-Gr).
- Vg-10 maximum casting speed
- D-Gw casting rolling
- D-B boundary deformation
- Both Deformations overlap to the total deformation (D-Ge), the becomes larger than the limit deformation (D-Gr) and therefore critical becomes.
- Exceeding the boundary deformation leads to internal cracks solid / liquid at the phase boundary and thus to reduce quality of the strand and to reduce casting reliability.
- the strand experiences increased internal deformation (D) through the Deformation (D-R) when it bends back in segment 4 from the inner circular arc into the horizontal, which, however, is not critical can be because the number of bending points in the "design" the system is chosen so that the reverse bending process at maximum No critical internal deformation in the casting speed Strand shell of the most crack-sensitive steel grade can trigger.
- Figure 6 in Figure 5 shows the procedural features the invention using the example of a vertical turning system, Figure 6, schematically.
- the inner deformation (D) of the strand shell (3) is never in a moment of solidification, H. from the mold exit critical to the end of scaffold 13. This is due to the distribution the total strand thickness reduction from 20 mm to, for example 10 mm in segment 0 (D-Gw) and 10 mm in frames 1 to 13 (D-SR) ensured according to the invention.
- This machine configuration with a maximum casting speed of 10 m / min and a maximum capacity of approx. 3 million t / a represents an extremely advantageous solution when using the Invention represents, in which a minimal rate of deformation of the strand occurs during its solidification.
- a segment should preferably be an odd one Number of 3, 5, 7 or 9 pairs of rollers (15) consisting of Lower (16) and upper roller (17) can be built. Every segment alternately consists of a pair of driven rollers (18), which is position and force controlled with a hydraulic system (19) and two with a hydraulic system (20) in the area the top rollers (17) connected non-driven roller pairs (21), which are provided with a machine element (22) that it allowed the pair of rollers of the top web in the casting direction by one Angle of z. B. to allow +/- 5 ° to swing in any casting situation for a given decrease in strand thickness, the strand if secured its shape.
- This structure of segments 1 to 13 leads to an optimal one Strand guidance in any type of distribution of strand thickness reduction, every casting situation, every kind of steel grade, with regard to their internal crack sensitivity, d. H. Critical Deformation Limit and the use of a minimum of hydraulic Systems per pair of rollers. So come 0.66 hydraulic systems per pair of rollers.
- the use of driven Roll pairs of 0.33 units per roll pair a mechanical engineering Minimum at maximum procedural and qualitative effect on the strand to be cast and its surface and interior quality, d. H. for example a minimal one Structure and a minimized accumulation of tensile stresses in the Strand shell between the driven roller pairs.
