Definitions
- the invention relates to a device for the continuous casting of metals, in particular steel, with a plurality of successive segments, each of which forms the strand guide for casting strands of different widths by means of pairs of rollers, the rollers being rotatably mounted on cross members of a segment frame and the cross members in each case are braced with strand guide frames on both sides.
- Such devices are e.g. known as guides for a thin metal strip (EP 0 941 787 A1).
- an adjusting device for setting a crowning of the roller gap is assigned to a pair of guide rollers which form a roller gap. This cannot be used for other problems.
- a cast slab profile is essentially an image of the roller gap geometry in the area of the residual solidification of the casting strand. Different strand widths and casting speeds lead to different roll deflections and to different deflections of the cross members of the segment frame and thus to a variable profile elevation.
- the roll deflection and the crossbeam deflection are determined by the position of the sump tip, the set thickness reduction and the steel grade.
- the rolling mill is fed slabs with changing wedge shapes due to the profile elevation, which in turn leads to problems with low final roll thicknesses.
- the invention has for its object to reduce such variable profile increases in the area of final solidification, so that the consequences described can not occur during later rolling.
- the object is achieved according to the invention in that, at least on the fixed side of the segment frame between the segment frame and a cross-beam which connects the strand guide frames on both sides, a force element lying approximately on the center axis of the strand is provided, the force transmission element of which engages on the segment frame and its receptacle is supported on the crossbar.
- the roll deflection and the crossbeam deflection can be influenced in such a way that a resulting profile elevation does not lead to malfunctions in the rolling mill, even with slabs slit lengthways.
- the force element can consist of a plunger that can be loaded on one side.
- the force element consists of a hydraulic piston-cylinder unit which can be acted upon from two sides.
- the force of the force element can be regulated as a function of the segment load by the cast strand. This avoids overloading the segment frame.
- This regulation can also take place in such a way that the force of the force element depends on the segment load against an expected one Profile elevation of the casting strand cross section is transferable to the support roller and truss deflection.
- the force of the force element can be adjusted on the loose side of the segment. This achieves the same or similar advantages that are described for the arrangement of the force element on the fixed side of the segment.
- Another application of the basic idea according to the invention is that the force of the force element can be adjusted at the same time on the fixed side and on the loose side of two opposing segment frames.
- a slitting device is arranged downstream of the segments.
- the setting of the profile elevation just in front of the slitting device allows precise shape influencing, so that the profile elevation required for rolling is fixed at this point.
- a special embodiment also consists in that the deformation characteristics of a segment are stored in tables in a computer and that the force of the force element can be called up from the stored values in accordance with the segment load. As a result, the values gathered from experience and from the design dimensions can easily be used for the appropriate bending line.
- a support roller segment is shown in front view, ie perpendicular to the direction of movement of the casting strand, which is explained in more detail below.
- the device for continuous casting of metals, in particular steel consists of a plurality of segments 1 which follow one another in the strand vein, in each of which segments of rollers 2, which may consist of split rollers 3 and upper and lower rollers, constitute the strand guide for the casting strand 4 ,
- the casting strand 4 can have a different width 4a.
- the casting strand 4 has a strand shell 4c in the area of the residual solidification 4b.
- the roller pairs 2 are rotatably mounted on segment frames 5, 6, a segment frame 5 acting as a fixed side and a segment frame 6 as a loss side , Both segment frames 5 and 6 can be adjusted relative to one another by means of pull cylinders 7, which corresponds to the thickness 8 of the casting strand 4.
- the segment 1 consisting of the segment frames 5 and 6 and the pull cylinders 7 is clamped on a strand guide frame 10 on both sides by means of clamping cylinders 9 (not shown).
- the segment 1 with the crossbar 11 is provided at least in the area of the residual solidification 4b.
- the force member 13 can consist of a plunger 14 that can be loaded on one side or a hydraulic piston-cylinder unit 15 that can be loaded on both sides.
- the force of the force element 13 can be regulated as a function of the segment load by the casting strand 4.
- the force of the force member 13 can also on the
- Loss side 6 of segment 1 can be made adjustable. In special cases it can be advantageous that the force of the force element 13 is at the same time on the Fixed side 5 and on the loss side 6 of two opposing segment frames 5; 6 is set.
- a plurality of force elements 13 can be assigned to each segment frame 5, 6.
- the deformation characteristic curve 19 of a segment 1 is stored in a computer in tables and the force of the force element 13 can be called up from the stored values in accordance with the segment load.
- the cross-section 20 of a segment 1 can be selected to minimize the force of the force element 13 as a function of the segment load.
