Description

The invention relates to a device for replacing a segment of a continuous casting plant according to the preamble of claim 1, a method according to the preamble of claim 12, and a corresponding segment of a continuous casting plant according to the preamble of claim 18.

The support rollers of the strand guide of a continuous casting plant are highly stressed and wear depending on the conditions of use and the rolling materials used. The service life of the support rollers is therefore of great importance for the availability of the continuous casting plant and thus for the casting performance, i. the production volume of continuous casting products.

The strand guide of a continuous casting plant is formed segmented in most cases, the support rollers are combined into individual segments. For replacement of support rollers, it is known in the art to remove such support roller segments and replace them with another segment. For this purpose, usually a ceiling crane is used, with which a segment from the strand guide is lifted vertically upwards, and then an exchange segment is again inserted vertically from above into the strand guide. Such a vertical expansion or installation of segments is eg off DE 10 2006 057 526 B4 . EP 1 506 066 B1 and EP 1 232 813 B1 known.

Out DE 36 39 611 Furthermore, a segment change device for a segmented continuous casting is known. Here, a horizontally extending rail guide is arranged below the casting platform, and thus above the strand guide, along which a carriage can be moved by means of a drive acting on associated wheels. On the frame of this car a pivot arm is pivotally mounted, which has a vertically downwardly extending guide arm and an attached extendable console. At the free end of this console a coupling device is provided, by means of which a segment of the continuous casting plant to be exchanged can be gripped and then lifted upwards out of the strand guide.

The above-mentioned references to the prior art have in common that a removal / installation of segments of a strand guide always takes place in the vertical direction upwards or from above. This principle is in the 4 for a conventional continuous casting plant 104 illustrated, where in the image area left a front view of the continuous casting 104 , and in the image area on the right a side view thereof is shown. If segments 102 a strand guide 108 , attached to a mold 107 the continuous casting plant 104 These are the segments to be exchanged 102 eg by means of a ceiling crane shown symbolically simplified 105 lifted vertically upward, as indicated by corresponding arrows. The disadvantage here is that the space above the strand guide for the removal / installation of the segments is required by the use of a overhead crane or a run below the casting platform carriage and is blocked accordingly. In addition, it can be problematic that the use of a ceiling crane is not possible with the necessary accuracy and possibly represents a risk of injury to the operating personnel.

Accordingly, the invention has for its object to make the replacement of segments in a continuous casting easier and to be able to perform in a shorter time.

The above object is achieved by a device having the features specified in claim 1, by a method according to claim 12, and by a segment having the features indicated in claim 18. Advantageous developments of the invention are defined in the dependent claims.

An apparatus according to the present invention is for replacing a segment of a continuous casting plant, which is formed from support rollers. In detail, the device comprises at least one expansion device by means of which at least one segment can be received out of a strand guide of the continuous casting plant, namely transversely to the casting direction and from the side of the strand guide. For this purpose, the expansion device may have a mounting arm with which the segment - as explained - can be added.

The invention likewise provides a method for exchanging at least one segment of a continuous casting plant consisting of support rollers. In this case, the segment is taken up by an expansion device and brought out of a strand guide of the continuous casting. Specifically, the segment is removed by means of the expansion device transversely to the casting direction and thus laterally from the strand guide out.

The present invention also provides a segment for a strand guide of a continuous casting plant comprising a segment frame in which an upper segment roll and a lower segment roll are rotatably mounted. These segment rollers are arranged parallel to one another and one above the other, so that a cast metal strip or casting material can be guided between the segment rollers. The Segment frame is C-shaped and has an open front side accordingly. This makes it possible to expand or replace the segment according to the invention from the strand guide of a continuous casting to the side when a cast metal strip is located between the segment rollers. This is particularly advantageous in the event of a casting demolition following system breakdowns - the otherwise high outlay for removing the metal strip is eliminated, so that the continuous casting plant is again ready for operation more quickly.

The invention is based on the essential finding that, for exchanging a segment, removal of the latter from the continuous casting plant transversely to the casting direction, i. takes place laterally out of the strand guide out. Likewise, a replacement segment at a point on the strand guide where a segment has previously been removed is also transverse to the casting direction, i. introduced or used herein from the side of the strand guide. Such an exchange segment installation may be made to be retrieved from a predefined place in a ready-to-install state or received by the mounting arm to be subsequently installed transversely of the casting direction and from the side of the strand guide. This leads to the advantage that a space above the continuous casting plant and its strand guide for the replacement of a segment is not needed or blocked.

In an advantageous embodiment of the invention, the device can be arranged or positioned laterally next to the strand guide of a continuous casting plant. In normal operation of the continuous casting plant, a sufficiently large distance from the system is provided for the device in this case. If replacement of a segment of the strand guide is required, the device may be moved over a lane e.g. moved up to the strand guide or casting direction of the system. Such a lane may be located on a normal floor surface of a production hall where the continuous caster is installed. In any case, bringing the device up to the strand guide of a continuous casting plant brings the mounting arm of the device into sufficient proximity to a segment to be exchanged, so that this segment can be picked up by the mounting arm. It is advantageous if the device on the roadway can also be moved longitudinally along the strand guide. This allows a needs-based positioning of the device along the strand guide, depending on the respective location of a support roller segment, which is to be replaced. For this purpose, the expansion device comprises a motor drive, with which it can be moved along the roadway.

In the device according to the invention, the at least one expansion device fulfills the function of a Verfahrgerüstes that can be moved or moved over the roadway to change as needed a distance or a position to the continuous casting. This movement over the roadway can preferably be automated or fully automatic, z. B. by specification or control of a control room and a central computer provided there. For a quick change of several segments, the device can also have several Verfahrgerüste in the form of the expansion devices with which then various points of the strand guide a continuous casting can be approached, depending on where a segment to be replaced is installed in the strand guide.

In an advantageous embodiment of the invention may be provided at the at least one expansion device in the lower region thereof, a chassis on which rollers are mounted, which roll on the road or the bottom surface of a production hall. This leads to the advantage that no separate guide devices or the like are required for a method or movement of the removal device on the roadway in order to change a distance to the continuous casting plant.

The roadway for the expansion device can advantageously be further developed in such a way that it has rails on which the wheels mounted on the expansion device roll. To minimize a risk of injury can be provided that such rails are embedded or sunk in the bottom surface of a production hall, comparable to tram rails in pedestrian areas. In any case, such rails ensure a robust and reliable movement of the expansion device, with relatively low required driving forces.

According to an alternative embodiment of the roadway, provision may be made for induction tracks to be embedded therein, which are followed by the removal device when its wheels are rolling on the roadway. This allows a flexible movement of the expansion device adjacent or along the continuous casting, and possibly also in a direction away from it, if necessary. Furthermore, such induction tracks are advantageous if the device - as explained - possibly has a plurality of expansion devices that are simultaneously moved over the roadway.

An adaptation of the expansion device to the height of a segment in which this is installed in a particular arcuate strand guide a continuous casting, can be achieved in a simple manner that the Removal device comprises a vertical stand on which the extension arm is guided in the vertical direction movable, for example by a rack drive or a cable drive. If a segment to be replaced is installed within the strand guide at a predetermined height, the mounting arm of the expansion device can be adjusted to this height by moving the mounting arm vertically upward on the stator.

A further improved adaptability of the expansion device to respective geometric dimensions of a strand guide and / or their segments, which may need to be replaced, can be achieved in an advantageous development of the invention in that the extension arm is equipped with a telescopic mechanism. Corresponding telescopic elements of the extension arm can then be extended in the direction of the strand guide in order to transfer a front end of the extension arm into a suitable position and to receive a segment to be exchanged, in order to subsequently lift this segment out of the strand guide laterally.

Regardless of the equipment with a telescopic mechanism may be provided for the mounting arm of an expansion device that at the front free end of a coupling device is mounted. By means of this coupling device, a segment of a strand guide to be exchanged can be suitably accommodated, e.g. by positively acting dowel pins or by force-acting clamping arms that can be operated, for example, electrically or hydraulically.

A flexible use of the mounting arm to adapt to different geometries or dimensions of the strand guide and / or a segment installed therein can be further improved by the mounting arm is attached to the expansion device via a hinge. By a suitable embodiment or position of the rotary joint of the expansion arm can be pivoted about a horizontal axis and / or about a vertical axis relative to the expansion device. This means that a front free end of the mounting arm can be moved to the left or right as it pivots about the vertical axis. Upon pivoting of the mounting arm about the horizontal axis, its front free end is moved up or down. In this way, an adaptation of the mounting arm to the geometric dimensions of a strand guide can be achieved in a flexible manner, when the expansion device has already been moved in the vicinity, to seize a segment to be exchanged. This can be further improved by the already explained telescopic mechanism of the mounting arm.

A removal of a disassembled segment, which has been lifted laterally out of the strand guide by means of the mounting arm, can be simplified in that the device according to the invention has at least one transport device with a storage surface on which the lifted-out segment can be deposited. This removal of the raised segment can also be done by the mounting arm, thanks to which elucidated pivotability about the axes of the rotary joint, with which it is hinged to the expansion device. The further handling of this disassembled segment may be provided by the transport device - together with a segment deposited thereon - being moved on said roadway transversely to the strand guide and / or along the strand guide in order to open the segment for further processing, e.g. repair or repair in a segment workshop. In the same way, the transport device can serve to supply the removal device with an exchange segment, which is then introduced by means of the mounting arm into the strand guide from the side and installed therein. For this purpose, the transport device can have a delivery area on which an exchange segment is stored, which is then picked up by the mounting arm.

With regard to the abovementioned laying down of a disassembled segment on the depositing surface of the transporting device, or taking up of an exchanging segment from the provisioning surface of the transporting device, which can take place in each case by the mounting arm, it is understood that in preparation for this, the transporting device via the carriageway has been moved in sufficient proximity to the expansion device, such that then the front free end of the mounting arm extends to the storage area or provision area of the transport device.

In an advantageous embodiment of the invention, it is possible that the transport device is equipped with a crane, with an exchange segment, which is located on a delivery surface of the transport device, to a defined place, e.g. on the floor surface of a production hall, for the purpose of a subsequent takeover by the mounting arm of an expansion device. Likewise, such a crane may serve to receive and transfer to a storage area of the transport means a segment which has already been exchanged and which has been deposited by the assembly arm of a removal device in a defined place (for example on the floor of a production hall).

Regardless of how a replacement segment of the mounting arm of a Removal device is taken or taken over (either directly from a staging area of a transport device, or from a defined place on which previously an exchange segment of the staging area of a transport device has been stored, for example by means of a crane), is advantageous if the exchange Segment of the mounting arm, preferably of the provided at the front free end of the mounting arm coupling device is already taken up in the position in which the replacement segment is then to be inserted in the strand guide of the continuous casting. This prevents "on-site", ie adjacent to the strand guide immediately before the lateral insertion of the replacement segment a cumbersome and possibly risky turning of the replacement segment, and ensures a speedy installation of the replacement segment within the strand guide.

The movement of the transport device on or along the roadway can be done by rollers, rails or guided by induction tracks, in the same manner as explained above for the expansion device. Preferably, the transport device is also equipped with its own motor drive. As already explained, the direction of travel of a transport device on the roadway can run transversely and / or longitudinally to the casting direction or to the strand guidance of a continuous casting plant.

The use of at least one transport device facilitates handling for the removal of replaced segments and / or for the provision of replacement segments which are to be installed "freshly" in the strand guide of a continuous casting installation. In any case, the use of a hall crane is unnecessary thanks to such a transport device.

To carry out the method according to the invention, it is expedient for an exchange segment to be installed from the mounting arm of the expansion device in the strand guide at the location from the side from which a segment is lifted out of the strand guide to the side of the mounting arm has been. The handling of a raised segment and an exchange segment to be used for it is facilitated if - as just explained - in sufficient proximity of the expansion device, a transport device is available, which has a storage area for a disassembled segment and a delivery area for an exchange segment.

Finally, in a step (vii), the above steps (i) to (vi) are carried out in reverse order with a disassembling segment to be installed in the strand guide of a continuous casting machine.

With the present invention, it is also possible, instead of a single segment of support rollers, to have segment groups, i. a plurality of such segments to replace at the same time. For this purpose, provided at a front free end of the mounting arm of an expansion device coupling means may be formed accordingly to receive such a plurality of segments and then lift out laterally from the strand guide. Mutatis mutandis can be introduced by the mounting arm and a segment group from the side into the strand guide, preferably at the point from which previously lifted a segment group lifted or has been removed.

Below are with reference to the 1 and 2 a preferred embodiment of a device according to the invention 100 and its components, which explains how to replace a support roll segment 102 a continuous casting plant 104 serves. It should be noted at this point that the same features in the drawing are each provided with the same reference numerals. The drawing is merely simplified and shown in particular without scale.

In the 1 is a continuous casting plant 104 shown simplified in principle in a side view. Below a mold 107 closes an arcuate strand guide 108 on. The casting direction, along which a cast metal band M through the strand guide 108 is guided in is 1 With " G " designated.

The continuous casting plant 104 is in the 2 shown in a front view. It can be seen here that the strand guide 108 is formed segmented, and thus individual segments 102 each formed by support rollers (not shown).

For repair and / or maintenance of the continuous casting plant 104 may be required segments 102 replace and from the strand guide 108 to highlight, and then through exchange segments 103 (see. 1 ) to replace. For this purpose, the device according to the invention comes 100 for use, which is now explained in detail:

The device 100 includes at least one expansion device 106 that have a mounting arm 110 has and over a roadway 112 can be moved. This roadway 112 is located, for example, on the floor surface of a production hall in which the continuous casting plant 104 is installed. The expansion device 106 fulfills the function of a traveling scaffolding, which is on the carriageway along the casting direction G (in 1 through the arrow " 115 "Marked") and / or transversely to the casting direction or strand guidance 108 (in 2 through the arrow " 114 Can be moved). For this purpose, the expansion device has a motor drive 116 who is on rollers 117 acting on the road surface 112 roll.

The expansion device 106 further includes a vertical stand 118 where the mounting arm 110 is guided movably in the vertical direction. This is in the 1 and 2 each indicated by the vertical double arrow. The mounting arm 110 is with a telescopic mechanism 119 equipped (cf. 2 ), wherein at a front free end of the mounting arm 110 or a telescopic element of the telescopic mechanism 119 a coupling device 120 is provided in 2 simplified and only symbolically represented by a hand. This coupling device 120 may be equipped with gripping elements, clamping elements or contact pins, which in any case a receiving a segment 102 . 103 through the mounting arm 110 enable.

The mounting arm 110 is at the expansion facility 106 over a swivel joint 121 appropriate. This makes it possible that the mounting arm 110 relative to the expansion device 106 around a horizontal axis (as in 2 shown) and / or about a vertical axis (for simplicity in FIG 2 not shown) can be pivoted.

The device 100 further comprises at least one transport device 122 , which also have associated roles on the road 112 can be moved. The transport device 122 can have its own motor drive, with the rollers 117 is in operative connection, and for simplicity not shown and designated.

At the transport facility 122 For example, a storage surface (not shown) and a delivery surface are provided. On the counter space can be at least one replacement segment 103 to feel like it is in 1 is shown simplified.

The invention now works as follows:

If for a segment 102 the continuous casting plant 104 a replacement is required, the expansion device 106 the device 100 over the roadway 112 adjacent to the location of the strand guide 108 driven, where this segment 102 in the strand leadership 108 is installed. This method of expansion 106 to the said point of the strand guide 108 can in the direction 114 , ie transverse to the casting direction G or for strand guidance 108 take place, and possibly also in the direction 115 , ie along the strand guide 108 or parallel to it. Anyway, the expansion facility 106 sufficiently close to the strand guide 108 moved up so that the segment to be replaced 102 from the mounting arm 110 can be included. A fine adjustment of the mounting arm 110 , for receiving the segment 102 , can also by means of said telescopic mechanism 119 take place, wherein a longitudinal extent of the mounting arm 110 is extended appropriately by moving out of associated telescopic elements to the segment to be replaced 102 heranzureichen. After the segment 102 from the mounting arm 110 , and preferably by the arranged at the front free end coupling means 120 has been included, the segment becomes 102 then laterally from the strand guide 108 moved out or removed. This is in the 2 symbolized by the right-hand arrows, located on the right side of the strand guide 108 are located.

In the 3 is a segment according to the invention 102 shown in cross section, namely in the upper illustration of 3 in a state when it is in the strand guide 108 is installed, and in the lower part of 3 in a disassembled state. Specifically, the segment includes 102 a C-shaped segment frame 124 who has an open frontal 130 having. In the segment frame 124 are an upper segment roll 126 and a lower segment roller 128 recorded rotatably mounted.

In the installed state of the segment 102 is the open front 130 of the segment frame 124 on a mounting frame 132 attached, eg by means of retaining pins 134 or the like (eg screwing). Thus, the segment forms 102 if its C-shaped segment frame 124 on the mounting frame 132 is attached, a closed segment frame. In operation of the continuous casting plant 104 runs the cast metal band M between the two segment rollers 126 . 128 through, as the upper illustration of 3 shows.

To replace the segment 102 becomes the front of the segment frame 124 from the mounting frame 132 solved, so that subsequently the segment 102 with its C-shaped segment frame 124 laterally from the strand guide 108 can be moved out. The lower illustration of 3 makes it clear that this is possible even when the metal band M still between the segment rolls 106 . 108 had found.

After removal of the segment 102 can this from the mounting arm 110 for example, directly on a storage surface of a transport device 122 be put to the preparation of which in the vicinity of the expansion device 106 has been moved. Then, an exchange segment 103 , which is located on the delivery surface of the transport device 122 located, then from the mounting arm 110 or the coupling device provided thereon 120 be recorded. As a result, then this exchange segment 103 through the mounting arm 110 from the side into the strand guide 108 moved in (in 2 through the right of the strand guide 108 arranged arrows, each pointing to the left, in the direction of the strand guide 108 ), and suitable in strand guidance 108 installed, preferably at exactly the point where previously the segment 102 has been singled out.

Various installation positions for a segment 102 or an exchange segment 103 , in particular because of the arcuate strand guide 108 may result from the device according to the invention 100 be easily approached by - as explained - the mounting arm 110 on the stand 118 in the vertical direction to this point of a segment 102 . 103 is moved. Another flexible positioning of the mounting arm 110 , depending on different geometries or dimensions of the strand guide 108 and / or a segment to be replaced 102 . 103 , is by pivoting the mounting arm 110 around the axes of the swivel joint 121 guaranteed.
