MULTI-STRING CONTINUITY PLANT TECHNICAL AREA

The invention relates to a multi-strand continuous casting for the production of metal strands with billet or billet cross section with a strand guide comprising a directional zone equipped with Treibrichtaggregaten, wherein a plurality of strand conveying direction successively arranged Treibrichtaggregate in a common scaffold with comb-like uprights in between the Stehern formed receiving openings are arranged and each Treibrichtaggregat a pair of rollers with an outer bow roller and a relative movable inner bow roller in associated roller carriage and a adjusting device for one of the two rollers, and optionally a rotary drive for one of the rollers comprises.

Treibrichtaggregate be used in single- or multi-strand continuous casting, especially in continuous casting for the production of steel strands with different strand cross-sections to the straight an arcuate strand guiding zone continuous, solidifying metal strand in the transition region to the horizontal outlet roller table again just to bend and defined with respect to the pullout speed ensure uniform transport through the strand guide. Greatering units can also be used to carry out a so-called soft reduction, whereby an improvement of the microstructure is achieved by this strand deformation in the final solidification region just before the sump tip.

STATE OF THE ART

WO 2005/120746 A2 shows a multi-strand continuous casting plant for casting metal strands with a slab cross-section. The roles of the inner bow for each strand guide of a strand are supported separately in independent roller carriers; the roller carriers are mounted in a common support or segmental frame. Furthermore, the roller carriers are displaceable on guides of the support frame via a respective adjusting device. The roles of the outer arch of both strand guides are supported in the common support or segmental frame and form the fixed side of the strand guide. EP 941 787 A1 shows a strand guide segment for a slab plant, in which a positioning device is supported on a crossbeam. Although the mechanical construction is simplified by the common support frame or segment frame, several strands must always be shut down when changing the reel so that maintenance is costly.

From EP 767012 A2, a maintenance-friendly precision rolling stand is known in which the upper roller is articulated via a setting device on a crosshead.

Drive rectifying units usually comprise a pair of rollers, which is supported in a scaffolding frame. A role of the pair of rollers, preferably the role of the bow inner side roller stand is adapted to adapt to changing strand thickness in the frame relative to the other role and is pressed by a hydraulic adjusting cylinder to the strand. This role is usually associated with a rotary drive. Several of these propulsion units are mounted one behind the other in the strand conveying direction on a common support frame and form the straightening zone in the continuous casting plant. A continuous casting machine with individual drive-straightening units in this arrangement is already known from WO 03/070399 A1, DE 10 2004 057 427 A1 or DE 22 39 966 A1.

Treibrichtaggregate the generic type, however, are designed for the joint straightening several side by side funded steel strands with billet or billet cross section, are already known from DE 30 34 444 A1. A plurality of drive-straightening units, each formed by a pair of rollers, are arranged in a common support frame. This support frame has bow inside open chambers in which the rollers of the drive unit are mounted with their chocks. The chocks or bearing housings of the adjustable castors are articulated on hydraulic cylinders, which in turn are supported on the supporting framework. When changing the drive unit, there is a high assembly cost, since it is necessary to release the hydraulic cylinder from its anchorage in the support frame and also to solve the corresponding supply lines, such as pressure medium connections.

From DE 27 31 748 A1 also a straightening roller frame is known in which a plurality of successive pairs of rollers are arranged in a comb-like arranged guides a machine stand. The individual rollers are supported by bearing housings on a cross member, which cooperates with the comb-like guides. Each cross member is adjustable by two pressure medium cylinder to the cast strand. Also in this case, it is necessary for disassembly of the driving straightening unit to release the cross member of the pressure medium cylinders, wherein the pressure medium cylinder can remain in the system.

PRESENTATION OF THE INVENTION

The object of the present invention is therefore to avoid the disadvantages of the prior art and to propose a multi-strand continuous casting with a straightening zone, which is characterized by low maintenance susceptibility, as well as easy assembly and disassembly with a case-by-case role change.

This object is achieved on the basis of a multi-strand continuous casting of the type mentioned in that each Treibrichtaggregat comprises a crosshead, which is releasably connected to the receiving opening for the Treibrichtaggregat forming stanchers that on the crosshead the adjusting device for the engageable inner bow Is hinged roller that each roller of the roller pair is supported in a roller carriage and the roller carriage of the inner roll of paper is guided slidably on guides of the uprights and that the roller carriage of the inner-bow roller is connected to the adjusting device. Due to this particular configuration of the individual components of the propulsion unit, it is possible to remove or reinsert the entire propulsion unit with the release of a few fastening elements as a modular component, in particular also with the adjusting device for the driven inner arc roller, from the support framework common to several propulsion aggregates.

The roller carriage of the outer-bow roller and the roller carriage of the inner-bow roller are articulated on the crosshead, wherein the roller carriage of the inner-bow roller is articulated distance variable to the roller carriage of the outer-bow roller. This articulation is preferably carried out with support tabs, which allow a relative movement of the two roller carriages to each other. Thus, the joint installation and removal is easily possible and it can be compensated structural deviations on the skeleton and especially on the scaffold of the propulsion unit. It is thus achieved that on the one hand fixed the crosshead to the uprights and on the other hand, the roller carriage of the outer arch roller can be supported and secured in the ground area on support brackets in the receiving opening of the scaffold formed by the uprights. The outer bow rollers form here, as in the entire strand guide framework, the fixed side of the strand guide on which the cast metal strand is supported on its transport through the continuous casting.

The media supply for the individual Treibrichtaggregate in the straightening zone can be substantially simplified by each scaffold is assigned a media supply system for the supply of arranged in this scaffold Treibrichtaggregate and the individual Treibrichtaggregate by automatic dome devices when inserting the Treibrichtaggregate in the receiving opening with the media supply system are detachable. Media supply lines are guided on the scaffolds to the individual Treibrichtaggregaten, which open in the bottom region of the respective receiving opening to support brackets in a coupling half of a multi-coupling. At the roller carriage of the outer bow roller, the further coupling half of the multi-coupling is arranged. When placing the respective roller carriage of the outer roll on the support bracket, the 2/12 Austrian Patent Office AT506 824B1 2013-01-15

Multi-coupling closed for all required media. It can also be arranged several automatic quick couplings for different media next to each other. If necessary, coolant, lubricant, hydraulic oil, electricity, compressed air and other necessary media can be passed through this multi-coupling. In addition, individual media supply lines are routed to the respective components of the propulsion unit.

Thus, a flat resting of the inner-bow roller on the metal strand is securely ensured and tilting forces are safely avoided, it is appropriate that the adjusting acts centrally on a engageable inner-bow roller of the drive set, is arranged in the direction of the longitudinal extension of the comb-like receiving opening and pivotally or articulated supported on the crosshead and is pivotally or hingedly attached to the roller carriage of the inner-bow roller.

In most cases, the inner-bow rollers are formed driven in the directional zone of a continuous casting. To ensure a compact design and easy assembly and disassembly of the propulsion unit, it is advantageous if the rotary drive for the inner-bow roller directly on the drive rectifying unit, preferably on the roller carriage of the inner-bow roller, supported and connected via an angular gear with the inner-bow roller. Preferably, the support of the rotary drive via a torque arm. The transmission is preferably designed as an angle gear.

Furthermore, it is expedient if individual casting strands in the directional zone are assigned to each other independent scaffolding and independent propulsion units in a multi-strand continuous casting. Mutual influences, as they occur especially in the case of propulsion units according to DE 30 34 444 A1, can thus be avoided.

For straightening zones of great length, the straightening zone for each casting strand of the multi-strand continuous casting plant is formed by a plurality of support structures arranged one behind the other.

Especially for the implementation of a soft reduction in the straightening zone and the necessary differentiated setting of a deformation wedge, it is necessary that the adjusting device for the engageable inner-bow roller each Treibrichtaggregates is individually controlled and adjustable.

As a hitch usually a hydraulically operated pressure cylinder is used. The adjusting device of this type comprises a pressure cylinder, a control block and a tracking system. The control block is connected by control technology via a data line with the system control device. With the tracking system, e.g. a position transmitter, the engageable inner bow roller is set at the start of casting on the thickness of the dummy bar and the subsequent hot strand. Also, the adjustment of the deformation wedge, i. the gradual roll-to-roll reduction in soft reduction is achieved by activating the setting device in response to the position signal from the track-following system.

For calibration of the tracking system calibration strips are arranged on the roller carriage of the inner-bow roller and the roller carriage of the outer-bow roller. The two roller carriages can be moved towards each other until the roller carriage of the inner-bow roller bears against the roller carriages of the outer-bow roller via the calibrating bars. This position determines a reference distance for the strand thickness adjustment to be made.

EMBODIMENT OF THE INVENTION

In Figures 1 a, 1 b and 2a, 2b, the straightening zone of a six-stranded multi-strand continuous casting is illustrated schematically in a longitudinal section and a cross section in two representations. On a plant foundation 1 are on supporting frame 2 a, 2 b, 2 c, 2 d two supporting frameworks 3 a, 3 b releasably secured with clamping screws. The support frame 3a is arcuate and the support frame 3b is straight. Together they form the straightening zone 5 of the continuous casting plant. Together, an arcuate, the straightening zone upstream strand guide continuous steel strand 6 is directed straight in Treibrichtaggregaten 7 and possibly also subjected to a soft-reduction in these scaffolds. As can be seen from FIG. 2, each casting strand is assigned an independent supporting framework 3a, 3b, whereby either one or two of these supporting frameworks are supported on a supporting frame 2d.

The scaffolds 3a, 3b are formed as a frame construction, wherein a series of comb-like uprights 8 project from this scaffold and form between them receiving openings 9, 7 are inserted into the individual Treibrichtaggregate. Each four arranged in a square stanchion form such a receiving opening. Each scaffold is designed to receive a plurality of propulsion units arranged one behind the other in the direction of transport of the strand, wherein the scaffold 3a receives three propulsion aggregates 7 and the scaffold 3b receives four propulsion units 7. Each of these Treibrichtaggregate 7 forms a self-contained unit that can be installed or removed as a whole.

The Treibrichtaggregat is shown in more detail in the figure. Each drive rectifying unit has a crosshead 11, which forms a support frame for all components of the drive rectifying unit. The crosshead 11 is releasably secured to four uprising, together a receiving opening 9 limiting stators 8 at the upper ends with connecting bolts 12 or with another fastener. An adjusting device 13, which is formed by a controllable pressure medium cylinder 13 a, is pivotally supported with pivot pin 14 in the crosshead 11. On the piston rod 15 of the pressure medium cylinder 13a, a roller carriage 16 is pivotally connected to a pivot pin 17. At the roller carriage 16, the inner-bow roller 18 is rotatably supported in support bearings. The roller carriage 16 is guided with its guide grooves 19a on radially aligned guides 19, usually on interchangeable guide rails, in the curved support frame 3a in the radial direction and in the horizontal expiring straight support frames 3b in the vertical direction.

Below the roller carriage 16 of the inner-bow roller 18 of the roller carriage 20 of the outer-bow roller 21 is articulated, which can be releasably secured with fastening elements on a bottom plate 23 in the receiving opening 9. In this case, a small relative mobility of the roller carriage 16, 20 is sufficient, which compensates for small differences in distance due to production and avoids assembly-related tension in the drive-bearing unit. For this purpose, support bolts 17 are guided on roller carriage 16 of the inner-bow roller 18 in non-illustrated slots on support plates 26, as well as the roller carriage 20 of the outer-bow roller 21. The roller carriage 20 is also radially on the guides 19 of the uprights 8 with guide grooves 19a vertically guided. The inner-bow roller 18 and the outer-bow roller 21 of a drive-straightening unit form a cooperating pair of rollers. [0029] The setting device 13 acts centrally on the adjustable inner-bow roller 18 via the roller carriage 16. Specifically, in the formation of the adjusting device as a pressure cylinder 13a this is aligned in the direction of the longitudinal extent of the comb-like receiving opening 9, so that the line of action of the applied force, the axis of rotation of the inner-bow roller 18 intersects (is not shown in detail).

With the adjusting device 13, the roller carriage 16 of the inner-bow roller 18 or the inner-bow roller 18 can be moved relative to the outer-bow roller 21 and thus be employed at the continuous casting of the continuous steel strand 6 with a predetermined or regulated contact pressure, which ensures straightening or a predetermined reduction in thickness (soft reduction or other metallurgical treatment). In order to be able to position the inner-bow roller 18 to a predetermined strand thickness, the adjusting device 13 or the pressure-medium cylinder 13a is assigned a control block 27 and a track-following system 28. As a tracking system, for example, encoders are provided which detect the position of the piston of the pressure medium cylinder. For calibrating this tracking system 28 Kalibrierleisten 30 on the two roller carriages 16, 20 are provided.

To ensure a constant casting strand transport speed and to carry out a soft reduction, the inner-bow rollers 18 of the individual drive-shaft units 7 are predominantly designed as driven rollers. Figure 1 shows powered inner-bow rollers 18a and non-driven inner-bow rollers 18b. The rotary drive 31 of the driven inner-bow roller 18a, which is formed by an electric motor, is fastened to the crosshead 11 and is connected to the drive shaft of the inner-bow roller 18a via a gear 32 preferably designed as an angular gear.

To supply the individual Treibrichtaggregate with the necessary for operation operating media, such as cooling water, lubricant, compressed air, hydraulic oil, electricity, control and regulating signals, each support frame 3a, 3b for each strand a common media supply system 33 for all in the associated with each support frame arranged Treibrichtaggregate 7. But there are also partial supply systems for special equipment possible. Starting from a common supply line lead branch lines for each medium to a common coupling device 34 on the bottom plate 23 of the respective receiving opening of a drive rectifying unit. A coupling half of this designed as a multi-coupling coupling device 34 is attached to the bottom plate and the second coupling half is attached to the roller carriage 20 of the outer bow roller 21. With the insertion of the roller carriage 20 in the receiving opening 9 and its attachment to the bottom plate 23 all media supply line are coupled together.

Figure 3 shows the essential components of a Treibrichtaggregates in a Schrägriss, as it can be installed as an assembly of the arcuate or straight scaffold essentially or be removed from this.
