Definitions
- the invention relates to a method and a device for continuous casting and direct deformation of a metal, in particular a casting strand made of steel materials, which has rectangular, block, pre-profile, billet or round format, guided after the continuous casting mold in a curved strand guide and with liquid Coolant is cooled secondarily and prepared for a uniform temperature field in the strand cross-section for the deformation process.
- the object of the invention is to generate the necessary temperature distribution in the casting strand and thus to optimize the deformation operation. Ren and at the end to achieve a usable structure of final solidification.
- the object is achieved according to the invention in that the casting strand is cooled by liquid coolant only in the longitudinal sections in which the casting strand is predominantly liquid in cross section, in that the casting strand is in a transition area in front of, in and / or behind a bending-straightening unit by isolating the respective heat-radiating outer surface in the temperature, essentially without liquid coolant, is further equalized by zone-wise heat radiation and that the casting strand is deformed on a dynamically variable reduction section due to a compressive strength measured via individual deformation rollers or roller segments, depending on the locally applicable compressive force becomes.
- the advantages are a casting or cooling process with a changed solidification or temperature profile in the strand cross-section, which is better to prepare the deformation process, and a reduction process with a continuous or variable reduction process, which lead to a largely error-free structure of the final solidification.
- the deformation process can be further optimized by forming the temperature field from elliptical, horizontally lying isotherms.
- thermo image is formed uniformly in the transverse and longitudinal direction of the core area in the strand cross section.
- Such a mode of operation is further supported by the fact that the casting strand is compressed in the transverse and longitudinal directions on the dynamically variable reduction section in the core area.
- the lengths of the side edges of a polygonal strand cross-section play an important role in cooling the casting strand. It is therefore of considerable rather meaning that the deformation is depending on the strand format, the strand dimensions and / or the casting speed vvoorrggeennoommmmeenn ⁇ .
- the shaping on the shaping path can be carried out according to two systems, in that the shaping is carried out by point pressing via individual shaping rollers or by approximate surface pressing using roller segments.
- a further refinement of the method in the case of surface pressing consists in the fact that when tapering the roller segments for different steel grades, different conicities are used when deforming over roller segments.
- the control or regulation the measurement and control technology of the deformation process.
- the method described at the outset provides for regulation in such a way that several roller segments are set in the normal position or with constant taper or with progressive taper or with variable taper, which can be set by the regulation. Then, depending on the deformation resistance determined, it can be deformed.
- the continuous or variable reduction curve is further supported in that the compression of the core area of the cast strand is regulated by detecting its resistance to deformation and / or the strand path.
- a shape-preserving supporting measure also consists in the casting strand being supported and guided, at least during the deformation, by support rollers resting on both side surfaces.
- the total amount of deformation energy supplied can be distributed by setting the rate of the reduction process to 0 to 14 mm / m.
- the generic method for continuous casting with direct deformation is designed in terms of control technology in such a way that the current deformation rate is matched to the respective temperature of the casting strand and / or to the casting speed by continuously measuring the deformation resistance on the individual deformation rollers or on the individual roller segments and the position of the sump tip is determined on the basis of the respective contact force and the coolant volume, the contact force, the casting speed and / or the extension speed of the deformed casting strand are regulated.
- Fixed initial values can also be obtained by first assigning a deformation rate with a fixed ratio to each deformation roller or roller segment.
- the generic device for continuous casting with direct deformation is designed in such a way that a largely dry area, largely without liquid coolant, is connected to the curved strand guide with the spray device for liquid coolant, which acts as insulation against the dissipation of radiant heat, surrounding the cast strand in a targeted manner , and that a reduction section covering the area of the bending-straightening unit, upstream or downstream, consisting of individual, hydraulically adjustable deformation rollers or consisting of several hydraulically adjustable roller segments is provided.
- a possibility of correction when the solidification cone tip migrates can also be compensated for by the fact that roller segments arranged in the strand running direction next to one or more fixed bending-straightening units can be displaced in the strand running direction or in the opposite direction.
- each reduction roller segment has at least two pairs of rollers, of which at least one adjustable deformation roller is equipped with a piston-cylinder unit.
- the different deformation forces can also be generated by the fact that, in the case of a rigidly arranged sub-deformation roller pair or a rigid sub-roller segment, the upper, adjustable deformation roller or the upper, adjustable roller segment in each case by means of two arranged one behind the other or in pairs outside the center line Piston-cylinder units are fitted per pair of rollers.
- roller division on a roller segment is selected as a narrow division in the range from 150 to 450 mm.
- bending-directing units arranged in the area of the radiation insulation are also insulated against heat radiation by the casting strand.

- FIG. 13A shows a deformation stand in the normal position
- FIG. 13B a deformation framework in the drive position and FIG. 13C the deformation framework with insulation.
- the strand cross-section 1 a could, however, also be a rectangular, a block, a pre-profile or a round format.
- the liquid steel material is cooled via a continuous casting mold 2 in a (curved) strand guide 3 with liquid coolant 4, for example water, and is regulated in a controlled manner to a uniform temperature field 5 in the strand cross section 1 a (cf. also FIG. 2).
- liquid coolant 4 for example water
- the curved strand guide 3 with a spray device 4a for the liquid coolant 4 is followed by a largely without liquid coolant 4, predominantly dry area 24, which serves as insulation 25 against the dissipation of radiant heat, specifically surrounding the casting strand 1, the possible insulation length in the longitudinal region indicated by arrows depending on the strand format 1d, the dimensions, the casting speed and the like.
- dry area 24 can extend, for example, as shown, covering the transition area 7 liquid / dry to the bending / straightening unit 8 with an upstream or downstream reduction section 9.
- the reduction section 9 consists of individual, hydraulically adjustable deformation rollers 10 or of several hydraulically adjustable roller segments 11, as can be seen in FIG. 1.
- the casting strand 1 is deformed on the basis of this improved temperature distribution on a dynamically variable reduction section 9 and on the basis of a compressive strength measured via the individual shaping rollers 10 or one or more roller segments 11, depending on the locally applicable compressive force.
- the temperature field 5 (FIG. 2) is formed uniformly in the transverse and longitudinal direction 1e of the core region 1c in the strand cross section 1a.

- the core area 1c is compressed up to a sump tip 1g.
- different conicalities 15 can be used for different steel grades by appropriately positioning the roller segments 11.
- FIG. 6 shows the “normal position” 16 of the roller segments 11, ie the taper is 0 °. Nevertheless, compression takes place.
- FIG. 7 a constant taper 17 is set for all roller segments 11.

- the compression of the core area 1c (FIGS. 4 and 5) of the casting strand 1 via the pressure cone 1h is first regulated by detecting the relevant deformation resistance and / or a covered strand path 20 (path detection). It is particularly expedient here for the temperature field 5 to be formed uniformly in the transverse and longitudinal directions 1e of the core region 1c. This results in so-called optimized isotherms 12.
- the isotherms 12 run particularly flat.
- the deformation resistance can, for example, under a single Deformation roller 10 can be measured by measuring the hydraulic pressure in a hydraulic line or other hydraulic component.
- support rollers 22, which do not allow a width of the casting strand 1 on its outer surface 1b, are expediently arranged on the two outer surfaces 1b during the deformation.
- the rate of the reduction process can be set to (currently) 0 to 14 mm per running meter of casting strand 1 and regulated.
- the control procedure for a soft reduction also takes place: the current deformation rate is matched to the respective temperature of the casting strand 1 and / or to the (set) casting speed (for example 3.2 m / min).
- the deformation resistance (for example via the hydraulic pressure) is continuously measured on the individual deformation rollers 10 or on the individual roller segments 11.
