Definitions
- the present invention relates to a strand guiding element for guiding a round strand in a continuous casting machine.
- a strand guide element for supporting and guiding a round strand with three, each rotatably mounted, strand guide rollers wherein a roller on a fixed frame and two other rollers are each arranged on a movable frame.
- the strand guide rollers of the strand guide element can be made manually to different strand diameter.
- a disadvantage of this solution is that the strand guide element can not be automatically adapted to different strand diameter, and that when adjusting two strand guide rollers must be made separately. How the strand guide element could be simplified, so that it is easy to automate, is not apparent from the font.
- Strand guiding element for guiding a strand in one

- a strand guide element is formed with only a single formed as a linear motor Anstellele- ment
- the strand guide rollers of the strand guide element can be easily and easily automated by the linear motor to the strand (for example, to different strand diameter) can be employed.
- the contact force of the strand guide rollers to the strand can be easily adjusted by extending or retracting the linear motor, so that, for example, the holding force of the strand guide element, which acts on a strand in a vertical or oblique strand guide, simply inserted. can be made.
- the traverse with the two wings, and the two wings with the linear motor are each hinged together, whereby stresses in the strand guide element can be effectively avoided.
- an intermediate region of the traverse, the first rocker and the second rocker is disposed between each of the first end portion and the first end portion.
- first strand guide roller is rotatably mounted, so that each two adjacent strand guide rollers have an angle of 120 ° to each other.
- the three strand guiding rollers have an angle of 120 ° to one another.
- the strand is guided centrally; In addition, this results in only low tensile stresses in the strand, which has a positive effect on the internal quality.
- a rectangular, in particular square, or octagonal strand it is advantageous for a rectangular, in particular square, or octagonal strand, if two first strand guide rollers are rotatably mounted in the intermediate region of the traverse, so that each two adjacent strand guide rollers have an angle of 90 ° to each other.
- the four strand guide rollers at an angle of 90 ° to each other.
- the strand is guided centrally;
- this in turn result in only low tensile stresses in the strand, which has a positive effect on the internal quality.
- a strand guide roll is a concave, i. has inwardly curved side surface.
- At least one strand guide roll preferably all strand guide rolls of the strand Strand guide element, is connected to a rotary drive for driving the strand guide roller.
- the linear motor is designed as a fluidbeaufschlagter cylinder, such as a hydraulic or pneumatic cylinder.
- the linear motor as an electric motor, e.g. as a Hubspindelantrieb is formed.
- the linear motor has a displacement measuring device for measuring the displacement of the linear motor and / or a force measuring device for measuring the contact force of the linear motor.
- the force measuring device is designed as a pressure measuring device for measuring the pressure in the fluidbeaufschlagten cylinder.
- the force measuring device is designed as a current measuring device for measuring the current in the electric motor.
- Strand guide rollers are arranged in a plane can be formed when the strand guide element relative to the support structure in at least one direction, preferably in both directions, the plane is floating. As a result, the strand guide element can be opposite to the
- FIG. 1c shows a plan view of a strand guiding element with three strand guiding rolls, each of which has a round, a triangular and a hexagonal strand
- Fig ld is a plan view of a strand guide element with four strand guide rollers, which leads a round strand
- Figure 2.3 is a perspective view of the strand guide element according to Fig la 4.5 each a perspective view of a strand guide with five strand guide elements
- Fig. 6 is a front view of Figs. 4 and 5
- Figs. 7, 8 are each a plan view of two embodiments of a strand guide with a strand guiding element according to Fig. 1a and a fixed support structure
- FIGS. 1 a - 1 c show a first embodiment of the strand guiding element 1 with three strand guiding rollers 6, 7, 8 used for guiding and supporting a steel strand 2.
- the strand guide element 1 a fixed cross member 3, a first rocker 4 and a second rocker 5; Traverse 3 as well as first and second rocker arms 4,5 each comprise a first end portion 3a, 4a, 5a, a second end portion 3c, 4c, 5c and an intermediate portion 3b, 4b, 5b therebetween.
- the end portions 3a, 3c of the Tra ⁇ verse 3 are each connected via a hinge with a first Schwin ⁇ ge 4 and a second rocker 5 movably connected.
- the first and 4b each connected via a hinge with a first Schwin ⁇ ge 4 and a second rocker 5 movably connected.
- Rocker 4 and the second rocker 5 are each a first, second and third strand guide roller 6, 8 and 9 rotatably mounted.
- two adjacent strand guide rollers eg 6 and 8, 8 and 9, or 6 and 9, each have an angle of 120 ° to each other.
- the strand 2 is guided centrally, which has a positive effect on the internal quality of the strand.
- the strand guide rollers 6,8,9 as non-driven rollers, engl, idle rolls, out ⁇ leads. Nevertheless, it would be possible, one or preferably all three strand guide rollers driven as so-called. Design drive rollers. For this purpose, the expert from the prior
- each end region 3a, 3c of the cross member 3 has a through hole for receiving an axle 13.
- each end region 3a, 3c of the traverse 3 has a recess for receiving an end region 4a, 5a of a rocker 4, 5.
- a hydraulic cylinder linear motor 10 is hingedly connected to the end portions 4c, 5c of the two wings.
- the strand guide rollers 6, 8, 9 have a concave, ie inwardly curved, curvature of the lateral surface, so that there is a line contact between a strand guide roller and the strand 2.
- the Hertzian pressure is reduced at the same load or the transferable forces can be substantially increased by a strand guide roller on the strand 2.
- Figures lb and lc show the use of the strand guide ⁇ elements 1 according to Figure la for supporting a triangular or hexagonal strand. 2
- Fig ld shows a schematic representation of a strand guide element 1 with four strand guide rollers 6,7,8,9.
- the difference to the strand guide element with three strand guide rollers according to FIG. 1 lc is that two first strand guide rollers 6, 7 are arranged in the intermediate region 3 b of the traverse 3.
- This embodiment is particularly suitable for round, rectangular (in particular square) and octagonal strand cross sections.
- FIGS. 2 and 3 show two perspective views of the strand guiding element according to FIG.
- FIGS. 7 and 8 show two ways in which a self-centering strand guide can be constructed:
- a strand guiding element 1 according to FIG. 1 a is arranged inside a frame of a fixed supporting structure 11 and, with respect to the supporting structure, via four pairs of springs 14 or other elastic elements
- the strand guiding element 1 can displace with the strand 2, so that by means of the linear motor 10 the strand 2 is clamped or pulled out only to the desired extent by the strand guiding rolls 6.
- FIG. 8 shows an alternative to FIG. 7 design of a self-centering strand guide. Again that is
- Strand guide element 1 is disposed within the fixed support structure 11, but the strand guide element 1 as it were in a fixed by the Stitzkon- 11 struction guide is guided.
- the degrees of freedom of the possible displacements are again represented by arrows.
- Figures 4,5 and 6 show different views of a strand guide with five strand guiding elements 1. Specifically, the strand guiding elements 1 are arranged one above the other in the casting direction 12. About the linear motors 10 can each
- Strand guiding elements 1 exert a defined clamping force on the strand 2, so that the cross section of the strand 2 can be reduced by the casting guide 12 subsequent strand guiding elements 1 (for example, by a so-called soft core or liquid core reduction). While the invention has been further illustrated and described in detail by the preferred embodiments, the invention is not limited by the disclosed examples, and other variations can be derived therefrom by those skilled in the art without departing from the scope of the invention.
