Definitions
- the invention relates to a method for casting and immediately thereafter Rollers and a device for supporting, guiding and deforming a metal, in particular a Stahlg screensstranges, in a pre-profile continuous casting with Soft reduction, wherein below the continuous casting mold on both sides of the cast strand opposite roller carriers are arranged, whose roles with the G manstrang in transport and / or deformation compound stand.
- roller carrier in a fixed frame arranged and divided into several, roller bearing segments, with adjustment communicating with the rollers carrying segments so articulated Coupled to each other are that each segment stands alone in any one Angle to the casting strand can be adjusted and adjusted and where the general Adjusting the roller carrier, the upper adjustment is used.
- Such Arrangement of hingedly interconnected roller carriers requires Supporting the forces over the entire length running fixed Frame that is elaborate and required over the entire support roll stand.
- JP-A-04210850 is a pre-profile continuous casting machine with soft reduction with a device for supporting, guiding and deforming a metal casting strand, being immediately below the continuous casting mold, at the outlet, on both sides the cast strand opposite roller carriers are arranged, their roles standing with the casting strand in transport and / or deformation connection and within the strand guide in the state of formation and further cooling of the Strand shell, so in a largely liquid interior each several, one behind the other arranged support and deformation rollers in sections conically to a Vorprofilsteg can be adjusted with a deformation force. It is just a matter of a circular bead resulting in a central sprue for a circular immersion nozzle eliminated.
- the invention is based on the object, a pre-profile, in particular an H-profile made of steel, with a rolling process in the soft reduction route, wherein the associated device a roller carrier in a small space at high Support forces, with the soft reduction of Vorprofilstrfiten in the art can be carried out that the segregations and porosities mentioned not more or not more to the same extent as before.
- the stated object is achieved by a method of the type described in the present invention solved in that the preliminary profile in the continuous casting mold to the Flanges and the web is precast with a bulge and that the pre-profile in the soft-reduction route at the bulges of the flanges and the web is so flat rolled that the flange outer surfaces and the web surfaces are largely flat. In doing so, the segregations and the porosities in the Web and in the flange significantly counteracted, so that they hardly occur.
- the pre-profiled bulges the Vorprofilsteg surfaces and / or the flange outer surfaces each as outward slightly curved, curved bulges are performed.
- the object is achieved by the device according to the invention characterized that within the strand guide in the solidification range for the soft reduction respectively several, consecutively arranged support and deformation rollers in sections conical to the Vorprofilsteg and the flanges with a in the Strangverlauf rising deformation force can be adjusted. This takes place in the Soft reduction route such deformation takes place on flanges and in the web, that the segregation is at least significantly reduced. In addition, will Porosities eliminated.
- pre-profiled elements produced in the continuous casting mold Bulges in the pre-profile web and on the outer surfaces of the flange in the solidification area for the soft reduction by means of the conical setting of one or more Roller carrier are deformable on the finished pre-profile.
- the deformation to the finished pre-profile is produced according to further features, that a section of several successively arranged support and deformation rollers forms an obliquely engageable roller frame. This will be added Adjustment of the roller frame all roles are made according to the angle of attack.
- the device is designed according to further improvements of the invention, that a roller frame for the strand top, consisting of parallel to the Strand course arranged longitudinal roller frame, which by means of a plurality of cross struts connected to each other, is formed and that on the longitudinal roller frame in the front area and in the rear area each support bearing for the deformation drives are arranged.
- a roller frame for the strand narrow sides is formed, respectively consisting of pairs of longitudinal roller frames running flat parallel to the strand upper side, the pairs per cast strand side by means of a variety of vertical directed to the strand profile transverse struts are interconnected.
- the perpendicular with its axis extending support and deformation rollers easily be put together to the flange outer surfaces.
- the deformation forces are thereby applied by the pairs of flat parallel narrow side roller frame of the two casting strand sides by means of each arranged at the ends tie rods transversely to the strand course with each other are connected.
- the tensile force can be fixed.
- the tie rods of adjustable hydraulic piston-cylinder units consist. This can be an adapted deformation force be exercised.
- the vertical deformation drives consist of adjustable hydraulic piston-cylinder units, the piston rods through slot-shaped openings of the flat-parallel longitudinal roller frame run and attached to the foundation frame.
- the device for supporting, guiding and deforming a metal takes place in a Vorprofilstranggitititititit for H-profiles, with Soft reduction instead, below the (not shown) continuous casting mold to both cast strand sides 1 a (left cast strand side) and 1b (right cast strand side) opposing roller carrier 2 are arranged, whose Supporting and deforming rollers 3 with the cast strand 1 in transport and / or deformation connection stand and form a strand guide 4.
- Strand guide 4 are in the solidification region 5 for the soft reduction in each case several, successively arranged support and deformation rollers 3 sections tapered to the Vorprofilsteg 6 and / or the flanges 7 with a strand in the course of the thirteenth Increasing deformation force employed.
- the continuous casting mold are pre-profiled Bumps 6a in Vorprofilsteg surfaces 6b and / or on the flange outer surfaces 7a in the solidification region 5 for the soft reduction by means of the conical Setting one or more roller carrier 2 deformed to the finished pre-profile.
- the pre-profiled bulge 6a is in each case of obtuse angle to each other Vorprofilsteg surfaces 6b and / or flange outer surfaces 7a formed.
- both cast strand sides 1a and 1b and the strand top 12 form several, successively arranged support and deformation rollers 3 obliquely engageable Roller frame 8.
- the support and deformation rollers 3 are in the roller frame 8 on the length of the soft-reduction section 9 for the flanges 7 of the casting strand 1 to common engageable flanged roll groups 10 summarized. In this way are formed in pairs longitudinal roller frame 8a and narrow side roller frame 8b.
- roller frames 8 are constructed such that a roller frame 8 for the strand top 12 consisting of parallel to the strand course 13 arranged longitudinal roller frame 8a are connected to each other by means of a plurality of transverse struts 14. On the longitudinal roller frame 8a are in the front region 15 and in the rear area 16 each support bearing 17 for pairs, vertically extending deformation drives 18 arranged.
- a roller frame 8b for the strand narrow sides 19th formed each consisting of flat parallel to the strand top 12 pairs 8c composed of longitudinal roller frame 8a.
- the narrow side roller frame 8b are by means of a plurality of correspondingly spaced, perpendicular to the strand course 13 directed cross struts 20 connected to each other.
- the pairs 8c of flat parallel Narrow-side roller frame 8b of the two cast strand sides 1a and 1b are by means of each arranged at one end 22 tie rods 23 transversely to the strand course 13 connected to each other, wherein at the end 21 a pivot bearing 8e for the unit is formed from the pairs 8c with cross struts 20.
- the units are thus in an approximately horizontal plane apart and together adjustable.
- the tie rods 23 consist of controllable hydraulic piston-cylinder units 23a. The tie rods 23 penetrate the two parallel to the strand course 13 extending
- the vertical deformation drives 18, which are also made of adjustable hydraulic Piston-cylinder units 18a may be made with their piston rods 18b through analogous slot-shaped openings 24 of the flat parallel narrow-side roller frame 8b out and hinged in the foundation frame 25.
