Definitions
- the invention relates to a method and a plant for producing a steel strip with a thickness of 2 to 25 mm by casting a steel strand with a thickness of less than 100 mm and then rolling the steel out of the casting heat, the cast strand having a cross-sectional reduction causing stretching in is subjected to at least one stitch.
- 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 new 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.
- the measures according to the invention result in a dense, void-free strand which is considerably reduced in thickness compared to the steel strand leaving the mold and which, over its entire cross section, also has a fine-grained casting structure, as is otherwise the case with a continuously cast steel strand only in the surface near the edge occurs.
- 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 strips can already be used without the need for substantial 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.
- the invention provides for the reduced-thickness cast strand to be cooled to a temperature in the range from 1000 to 1200 ° by spraying a cooling medium onto the cast strand and cooling the cast strand in this way using the casting heat in at least one stitch a degree of deformation of 5 to 85% is rolled out into a strip. Because of this The smallest final dimensions of up to approximately 2 mm can be rolled out.
- the application of the method according to the invention for the production of steel strips even of such smallest thicknesses is cost-effective since the production method does not require large plants with holding furnaces and many roll stands with the corresponding energy requirements.
- the object is achieved by a system consisting of a continuous casting plant with a funnel-shaped, oscillating mold with cooled walls, and a deformation device for the strand arranged at the mold outlet.
- a cooling device and the cooling device are preferably followed by a roll stand after the deformation device.
- the steel strand should be given a profile corresponding to the thickness profile of the finished strip when compressed. This measure is important for the method according to the invention, because basic profile changes are not possible in a simple manner when a strip is rolled out.
- the cast steel strand has a rectangular cross-sectional shape with convexly rounded narrow sides or an oval cross-sectional shape. This design 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, neither cracks in the edge area nor in the deformation device Irregularities occur on the strand surface.
- 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 is dimensioned such that the condition 0.05.
- v g (m / min) less than or equal to 1 k less than or equal to 1 m is satisfied, the value 0.05 being a dimensionally dependent component. Under this condition, 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 such large tensile forces must be applied when pulling the strand out of the shaping device that it leads to the formation of There may be cracks in the strand surface, which cannot be welded again even if the strand is deformed further.
- 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 shaping device 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 are adjustable against 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. However, 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. Dependent on The cooling device 4 arranged in front of the roll stand 5 is controlled by 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.
