Definitions
- the invention relates to a method for casting and immediately subsequent rolling and a device for supporting, guiding and deforming a metal, in particular a steel casting strand, in a pre-profile continuous casting installation with soft reduction, wherein opposite roller carriers are arranged below the continuous casting mold on both sides of the casting strand, the opposite of which Rollers are connected to the casting strand in transport and / or deformation connection.
- a device for supporting a metal casting strand, in particular for soft reduction in a pre-strip casting installation is known (EP 0 450 391 B1), wherein below the continuous casting mold, opposite roller carriers are provided on both sides of the casting strand, the rollers of which are operatively connected to the casting strand.
- Each roller carrier is arranged in a fixed frame and divided into several roller-bearing segments which are connected to adjusting devices, the roller-bearing segments being coupled to one another in such an articulated manner that each segment can be adjusted and adjusted at any angle to the casting strand and wherein the upper adjustment device is used for general adjustment of the roller carrier.
- Such an arrangement of articulated other connected roller carriers require a fixed frame running over the entire length to support the forces, which is complex and is required over the entire support roller frame.
- the invention has for its object to provide a preliminary profile, in particular an H-profile made of steel, with a rolling process in the soft reduction section, the associated device having a roller carrier in the smallest space with high supporting forces, with which the soft reduction of before - Profile strands can be carried out in such a way that the segregations and porosities mentioned no longer occur or no longer occur to the same extent as before.
- the stated object is achieved according to the invention by a method of the type described in the introduction in that the preliminary profile in the continuous casting mold is pre-cast on the flanges and on the web with a bulge and in that the preliminary profile in the soft-reduction section on the bulges of the flanges and of the web is rolled flat in such a way that the flange outer surfaces and the web surfaces are largely flat.
- the segregation and porosity in the web and in the flange are considerably counteracted, so that they hardly occur.
- the pre-profiled bulges of the pre-profile web surfaces and / or the flange outer surfaces are each designed as arcuate bulges that are slightly curved outwards.
- the object is achieved by the device according to the invention in that, within the strand guide in the solidification area for soft reduction, a plurality of support and deformation rollers arranged one behind the other are conically sectionally adjustable against the pre-profile web and / or the flanges with an increasing deformation force as the strand progresses. This causes such deformation on the flanges in the soft reduction section and in the jetty instead that the segregations are at least significantly reduced. Porosities are also eliminated.
- the pre-profiled bulges produced in the continuous casting mold in the pre-profile web and / or on the flange outer surfaces in the solidification area can be deformed for the soft reduction by means of the conical adjustment of one or more roller carriers to the finished pre-profile.
- the desired compression of the material while eliminating the central segregation and the porosity is favored by the high compression.
- the deformation to the finished pre-profile is produced according to further features in that a section of a plurality of support and deformation rollers arranged one behind the other forms an obliquely adjustable roller frame. This means that when the roller frame is adjusted, all rollers are adjusted according to the angle of attack.
- the support and deformation rollers in the roller frame form web-roll groups that can be adjusted for the pre-profile web of the casting strand along the length of the soft-reduction section.
- the device is designed in such a way that a roller frame for the top of the strand, consisting of longitudinal roller frames arranged parallel to the strand path and connected to one another by means of a large number of transverse struts, is formed and that the longitudinal roller frames in the front area and in the rear area each support bearings for the deformation drives are arranged.
- the mounting surfaces for the pivot bearings of the support and deformation rollers running horizontally with their axis are created.
- a roller frame is formed for each of the narrow sides of the strand, each consisting of pairs of longitudinal roller frames running parallel to the top of the strand, which are connected in pairs on each side of the casting strand by means of a plurality of transverse struts oriented perpendicularly to the strand.
- the deformation forces are exerted in that the pairs of flat-parallel narrow-side roller frames of the two casting strand sides are connected to one another transversely to the strand profile by means of tie rods arranged at the ends.
- the tractive force can be fixed.
- tie rods consist of controllable hydraulic piston-cylinder units. This allows an adapted deformation force to be exerted.
- connection of the roller frames for the top side of the strand and the narrow sides of the strand is particularly advantageous in that the vertical deformation drives consist of controllable hydraulic piston-cylinder units, the piston rods of which run through slot-shaped openings in the parallel flat longitudinal roller frames and are fastened to the foundation frame.
- the device for supporting, guiding and deforming a metal, in particular a steel casting strand 1 takes place in a pre-profile continuous casting installation for H-profiles, with soft reduction, with below the continuous casting mold (not shown in more detail) on both casting strand sides 1a (left casting strand side ) and 1 b (right casting strand side) are arranged opposite roller carriers 2, the support and deformation rollers 3 of which are in transport and / or deformation connection with the casting strand 1 and form a strand guide 4.
- a plurality of support and deformation rollers 3, arranged one behind the other, are tapered in sections against the pre-profile web 6 and / or the flanges 7 with an increasing deformation force in the strand profile 13.
- pre-profiled recesses 6a in pre-profile web surfaces 6b and / or on the flange outer surfaces 7a in the solidification area 5 are deformed for soft reduction by means of the conical adjustment of one or more roller carriers 2 to the finished pre-profile.
- the pre-profiled bulge 6a is formed in each case from pre-profile web surfaces 6b and / or flange outer surfaces 7a running at an obtuse angle to one another.
- a plurality of support and deformation rollers 3 arranged one behind the other form the obliquely adjustable roller frame 8.
- the support and deformation rollers 3 are in the roller frame 8 to the length of the soft reduction path 9 for the flanges 7 of the casting strand 1 combined to form jointly adjustable flange roller groups 10.
- longitudinal roller frames 8a and narrow side roller frames 8b are formed in pairs.
- roller frames 8 are constructed in such a way that a roller frame 8 for the top side 12 of the strand, consisting of longitudinal roller frames 8a arranged parallel to the strand path 13, are connected to one another by means of a plurality of cross struts 14. Support bearings 17 for paired, vertically extending deformation drives 18 are arranged on the longitudinal roller frames 8a in the front area 15 and in the rear area 16.
- a roller frame 8b is formed for the strand narrow sides 19, which is composed in each case of pairs 8c of longitudinal roller frames 8a running parallel to the top of the strand 12.
- the narrow-side roller frames 8b are connected to one another by means of a multiplicity of correspondingly spaced-apart transverse struts 20 which are oriented perpendicularly to the strand profile 13.
- the pairs 8c of flat-parallel narrow-side roller frames 8b of the two casting strand sides 1a and 1b are connected to one another transversely to the strand path 13 by means of tie rods 23 arranged at one end 22, with a pivot bearing 8e for the unit consisting of the pairs 8c at the end 21
- Cross struts 20 is formed.
- the units can thus be adjusted apart and together in an approximately horizontal plane.
- the tie rods 23 consist of controllable hydraulic piston-cylinder units 23a.
- the tie rods 23 penetrate the two longitudinal roller frames 8a running parallel to the strand path 13 through openings 23b.
- the piston-cylinder units 23a are connected by means of joint heads 23c to connecting rods 8d of the narrow-side roller frames 8b.
- the vertical deformation drives 18, which can also consist of controllable hydraulic piston-cylinder units 18a, are guided with their piston rods 18b through analog slot-shaped openings 24 in the flat-parallel narrow-side roller frames 8b and articulated in the foundation frame 25.
