Definitions
- the invention relates to a plant for producing a steel strip with a thickness of 2 to 25 mm by deforming a cast steel strand.
- a system for producing a steel strip by rolling a cast strand directly from the casting heat is known (PATENT ABSTRACTS 0F JAPAN, Volume 8, No. 210 (M-328) (1647), September 26, 1984; JP-A-59 97 747 (A)).
- PATENT ABSTRACTS 0F JAPAN, Volume 8, No. 210 (M-328) (1647), September 26, 1984; JP-A-59 97 747 (A) the steel strand emerging from a continuous mold with parallel walls and not yet solidified with its less than 30 mm thick, already hardened strand shells is pressed together until the thickness of the steel strand is twice the thickness of the already hardened strand shell.
- the processes used in practice for the production of hot-rolled steel strip are generally based on a continuous cast slab, which, after it has completely solidified, is heated again to the rolling temperature and reduced in thickness in several passes and rolled out to form the strip. Because of the considerable thickness of the slabs used, up to nine roll stands are required for this. Plants for the application of such a method entail high investment costs because, on the one hand, the plants require a correspondingly large continuous casting plant, on the other hand, they require a multi-stand hot strip mill, the roughing stands of which have to be correspondingly compact due to the thickness of the slabs to be rolled out.
- At least one roll stand for a thickness reduction of 5 to 85% is preferably arranged downstream of the shaping device.
- a cooling device can be arranged between the deformation device and the roll stand.
- a dense, void-free strand is obtained which is considerably reduced in thickness compared to the steel strand leaving the mold, and which has a fine-grained cast structure over its entire cross section, as is otherwise only the case near a continuous cast steel strand Surface occurs. Because of the small thickness of the steel strand emerging from the funnel-shaped, in particular oscillating mold, and the subsequent reduction in thickness of the not yet solidified Steel strands are easily obtained with a thickness of steel that can be significantly smaller than 25 mm.
- the various parameters for casting the steel strand on the one hand and for reducing the thickness of the steel strand on the other hand are matched to one another such that the strand shells are sufficiently resistant to withstand the compression of the steel strand without breakthroughs.
- steel strands When the not yet solidified steel strand of 40 to 50 mm is compressed, steel strands are obtained which have a thickness of 10 to 20 mm. For some applications, such thin steel strands can already be used as strips, without the need for significant deformation during rolling. A degree of deformation of about 5% to improve the surface quality (skin pass) can be sufficient. After appropriate cooling, the strips, which are still slightly deformed in this way, can be coiled. If, however, strips with an even smaller thickness are required, it is provided according to the invention that the deformation device is followed by a cooling device and the cooling device is followed by at least one roll stand. With a system designed in this way, the reduced-thickness cast strand can be cooled to a temperature in the range from 1000 to 1200 ° C.
- the system according to the invention creates the prerequisites for influencing the cast strand in various ways.
- the steel strand when reducing the thickness, can be given a profile corresponding to the thickness profile of the finished strip. This measure is important for the invention because when a strip is rolled out, fundamental profile changes are no longer possible in a simple manner.
- the cast steel strand has a rectangular cross-sectional shape with convexly rounded narrow sides or an oval cross-sectional shape according to one embodiment of the invention. In terms of the device, this can be achieved by rollers which have contoured bales.
- This shape of the cross section ensures that a strand shell with a uniform thickness is formed during solidification, so that when the steel strand is compressed after exiting the mold in the deformation device, neither cracks in the edge region nor irregularities on the strand surface occur.
- the casting speed v g and / or the cooling intensity of the mold is controlled in such a way that the cast steel strand has a strand shell with a thickness of 5 to 10 mm when it emerges from the mold.
- the cooling effective length 1 k (m) of the mold distance between the lower edge of the mold and the casting level
- the condition 0.05 v g (m / min) less than or equal to 1 k less than or equal to 1 m is satisfied, with the value 0.05 being a dimension component.
- the solidifying strand is on average sufficient heat, for example withdrawn.
- the cooling should be so intensive that the inner surface temperature of the mold remains below 400 ° C, in particular between 200 and 400 ° C. In this case it is ensured that a sufficiently thick steel strand is obtained for further processing even after the cast steel strand has been compressed.
- a strand shell of the mentioned thickness is also resistant enough to withstand the forces occurring in the material when the cast strand is compressed without the formation of cracks.
- the cast steel strand is reduced in thickness by up to 75% immediately after it leaves the mold.
- a greater reduction in the strand thickness at this point should, however, be avoided, because otherwise when pulling the strand out of the shaping device such great tensile forces must be applied that cracks can form in the strand surface, which cannot occur even if the strand is subsequently deformed further can be welded again.
- an oscillating mold 2 which consists of a funnel-shaped upper part and a lower part with cooling walls arranged in parallel, the spacing of which is selected according to the thickness of the strand to be cast.
- a deformation device 3 by means of which the strand is compressed to a thickness of less than 25 mm, in particular 10-20 mm.
- the deformation device 3 consists, for example, of cooled plates which continue the broad sides of the mold 2 or a corresponding arrangement of driven pull-out rollers 3a which can be adjusted relative to one another by means of hydraulic cylinders 3b for compressing the cast strand 10.
- support rollers determining the profile should be assigned to the narrow sides.
- the diameter d of the pull-out rollers 3a should be between 0.5 m and 1 m, while the distance D of the beginning of the area of attack from the lower edge of the mold 2 should be less than 0.5 m. If a strip profile with elevation, for example in the middle of the strip, is required for further processing, the bales of the pull-out rollers can have a corresponding contour. A strip with such a profile promotes further processing, for example in a cold rolling mill.
- pull-out rollers with a different profile for example those with bottle-shaped bales, can also be used.
- the pull-out rollers 3a are followed by a cooling device 4, which can consist of ribbed or lattice-shaped cooled plates 4a.
- a cooling device which can consist of ribbed or lattice-shaped cooled plates 4a.
- cooling liquid is sprayed from nozzles 4b between the rods or grids of the plates 4a onto the solidifying strand shell.
- the cooling device 4 is immediately followed by at least one roll stand 5 which rolls out the cast strand 13.
- the thickness of the compressed strand is reduced by 5-85%, that is, in the case of a 10 mm strand, the thickness is reduced to a minimum thickness of about 2 mm using the casting heat.
- a thickness measuring device 12 is arranged behind the first roll stand 5 and determines the thickness profile of the rolled strand 10a over its entire width.
- the cooling device 4 arranged in front of the roll stand 5 is controlled as a function of the thickness profile determined at this point.
- deflection rollers 6, a further roll stand 7, a further cooling device 8, a pair of scissors 9 and a reel 11 can be provided for winding up the rolled strip 10b.
