Definitions
- the invention relates to a method and a continuous casting device for the dynamic setting of a casting strand made of metal, in particular steel, supporting and / or guiding roller segments on both sides, with at least two successive pairs of rollers which are positioned against one another by means of piston-cylinder units, which are both positionally as well as pressure-controlled, and the pairs of rollers on the casting train are then position-controlled and the hydraulic pressure is switched from position-controlled to pressure-controlled operation when the hydraulic pressure in a piston-cylinder unit reaches a predetermined value.
- the invention has for its object to expand the known task, namely to avoid damage to the roller segment due to excessive force effects by the setting method, moreover to eliminate bulges of the casting strand as far as possible by making the method accessible to a larger number of operating modes in continuous casting becomes.
- roller segments of billet and billet continuous casting devices wherein the roller segments are provided in the cold strand, warm strand and / or in the soft reduction area. This makes it possible to set roller segments in a way that is gentle and geared to the respective operating mode, even with blooms and billet strand cross-sections.
- An advantageous embodiment consists in that integrated, driven rollers arranged on the segment input side and / or on the segment output side of pivotable and / or parallel adjustable roller segments are switched over from the position-controlled to pressure-controlled operation depending on the process phase. This ensures force or pressure conditions that are individually matched to the respective operating mode.
- a continuous casting device for casting blooms or billet continuous casting profiles has a support roller stand downstream of the continuous casting mold and a bending-straightening unit.
- the procedural task of extending the method to a larger number of operating modes is achieved in terms of device technology according to the invention in that a device is arranged at least partially in front of the bending-straightening unit or completely behind the bending-straightening unit, with a plurality of hydraulically actuated piston Cylinder units with position or pressure-controlled, adjustable roller segments, each of which has at least one driven roller.
- the power transmission to the cast strand takes place in such a way that the driven rollers are provided on the segment input side and / or on the segment output side. As a result, even with a corresponding angular position of a roller segment, intense force is transferred to the casting strand or the cold strand.
- the drives for the driven rollers are designed in such a way that the drive motor for a driven roller is arranged together with a primary gear on one side of the segment frame in a vertical drive axis position. As a result, the power transmission is direct and the accessibility of the motors is advantageously simple.
- the hydraulic piston-cylinder units and the drive motors for driven rollers are each actuated in such a way that the adjustment and control concept for dynamic adjustment is divided into segment control and basic automation.
- the control and / or regulation is further designed in such a way that the segment control is formed at least from the respective operating strategy, a spring compensation, a maximum force controller, a minimum force controller and a position controller.
- the hydraulic piston-cylinder units adjust the guiding and transport force for the warm section, the cold section (start-up section) and for a soft reduction used in optimal sizes.
- the basic automation is formed at least from the respective operating mode, a torque controller and a speed controller.
- the driven rollers are each set to their optimal speed or to the optimal torque.
- control of the method is also advantageously designed in such a way that on each piston-cylinder unit two pressure transmitters spaced apart for different piston positions and one position transmitter for the piston of a piston-cylinder unit are provided, which are connected to the segment control. Finally, the regulation and / or control is completed by the fact that the drive motor for the driven roller communicates with the basic automation.
- the drawing shows exemplary embodiments of the continuous casting apparatus which are described in more detail below and on the basis of which the method is also described.
- Fig. 1 is a side view of a continuous casting device for bloom or
- Fig. 3 is a perspective view of the strand guide segments in
- FIG. 4 is a block diagram of the hiring-control concept, connected to a hot strand conveyor,
- Fig. 5 shows the hire-control concept for the cold strand conveyor
- Fig. 6 shows the control concept for a soft reduction section.
- Liquid steel flows from a distribution vessel 1 into a cooled continuous casting mold 2, which is set in vibration by means of an oscillation unit 3 in order to bring the casting strand 4 leaving the continuous casting mold 2 to external solidification and release.
- the casting strand 4 which is liquid on the inside, passes through cooling zones 6, 7, 8, 9 and 10 in a support roller frame 5 one after the other and enters a bending-straightening unit 11.
- the casting strand 4 further cooled, enters roller segments 13, 14, 15, 16, 17 (FIG. 1).
- the roller segments 13 to 17 each have at least two pairs of rollers 18.
- Each roller segment 13 to 17 is equipped with a pair of piston-cylinder units 19, which, however, are arranged on a center line one behind the other within a roller segment 13 to 17 and only line up an upper part of the respective roller segment, while the lower part rigidly on the segment frame 13a (to 17a) is arranged.
- roller segments 13 to 17, which are located opposite each other in pairs, are adjusted against one another in a controlled manner by means of the piston-cylinder units 19, the adjustment being carried out both position and pressure-controlled.
- the pairs of rollers 18 are initially positioned on the casting strand 4 in a position-controlled manner.
- the contact force is changed from position-controlled to pressure-controlled operation as soon as the hydraulic pressure in a piston-cylinder unit 19 reaches a predetermined value.
- the method is applied to the roller segments 13 to 17 of billet and billet continuous casting devices 20, the roller segments 13 to 17 being provided in the cold strand, warm strand and / or in the soft reduction area.
- driven rollers 23 integrated into the respective segment can depend on the process phase or the operating mode from position-controlled to pressure-controlled operation be converted in the piston-cylinder units 19.
- the continuous casting device with the support roller stand 5 downstream of the continuous casting mold 2 and the bending-straightening unit 11 then has a plurality of roller segments 13 to 17 which carry the driven rollers 23 and the piston-cylinder units 19 (FIG. 2).
- Each roller segment 13 to 17 has the piston-cylinder unit 19 on an upper roller conveyor 24, which is opposite a lower, rigid roller conveyor 25.
- a drive motor 29 with a primary gear 30 (FIG. 3) is arranged in a vertical drive axis position 28.
- a recruitment and control concept 31 is shown.
- the segment control 32 comprises the respective operating mode 34, a suspension compensation 35, a maximum force controller 36, a minimum force controller 37 and a position controller 38.
- the basic automation 33 is constructed at least from the respective operating mode 34, a torque controller 39 and a speed controller 40.
- pressure transmitters 41 spaced apart for piston positions and a position transmitter 42 for the pistons 43 of a piston-cylinder unit 19 are provided, which are connected to the segment control 32.
- the drive motor 29 for a driven roller 23 communicates with the basic automation 33 (FIG. 4).
