JP 2007-167874 A

  A conventional rolling line in which reverse rolling is performed is provided with a vertical rolling mill (edger) adjacent to a guide device for centering the rolled material. The vertical rolling mill is an apparatus for reducing unevenness in the width direction of a rolled material. For example, a vertical rolling mill includes a roller, and this roller is brought into contact with the end surface of the rolled material from the side to flatten the end surface of the rolled material.

  In the rolling line having the above configuration, the rolled material rolled by the rolling mill is reversed in the traveling direction after passing through the guide device and the vertical rolling mill, and is rolled again by the rolling mill. There has been a problem that the conveyance distance of the rolled material becomes long and the rolling pitch cannot be shortened. In reverse rolling, the rolling pass may reach several tens of times, resulting in a significant reduction in productivity.

  The present invention has been made to solve the above-described problems. An object of the present invention is to provide a side guide device that can shorten the transport distance of rolled material and improve productivity.

  The side guide device according to the present invention is disposed on the opposite side of the first guide device with the conveyance table interposed between the first guide device that contacts the rolled material conveyed by the conveyance table from the side, A second guide device that contacts from the side, and each of the first guide device and the second guide device is rotatably supported by the support body and the support body so that the rotation axis faces the vertical direction. A plurality of roller guides arranged along the conveying direction of the rolled material, a first drive device that rotates the roller guide, and a second drive device that moves the support so that the support approaches and separates from the rolled material , With.

  By using the side guide device according to the present invention, the distance for transporting the rolled material can be shortened and the productivity can be improved.

It is a figure which shows a part of rolling line provided with the side guide apparatus in Embodiment 1 of this invention. It is a top view of a part of rolling line shown in FIG.

  The present invention will be described in detail with reference to the accompanying drawings. The overlapping description will be simplified or omitted as appropriate. In each figure, the same or corresponding parts are denoted by the same reference numerals.

Embodiment 1 FIG.
1 is a view showing a part of a rolling line provided with a side guide device according to Embodiment 1 of the present invention. FIG. 2 is a plan view of a part of the rolling line shown in FIG. As described above, in a rolling plant such as a steel plant or a non-ferrous plant, reverse rolling is performed, for example, in a hot rolling line. FIG.1 and FIG.2 has shown the hot rolling line in which reverse rolling is performed as an example of a rolling line.

  Reference numeral 1 denotes a rolling mill for rolling the rolled material 2. The rolled material 2 is conveyed by the conveyance table 3. For example, the transport table 3 includes a large number of transport rollers (not shown). The transport roller is driven by a driving device (not shown). The rolled material 2 moves in a direction corresponding to the rotation direction of the conveyance roller while being placed on the conveyance roller as the conveyance roller rotates.

  In reverse rolling, the traveling direction of the rolled material 2 is reversed by the transport table 3. Thereby, the rolling material 2 repeats reciprocating movement, and is rolled by the same rolling mill 1 several times. For example, the rolled material 2 passes through the rolling mill 1 about 10 to 30 times and is rolled to a desired thickness. When rolling by the rolling mill 1 is completed, the rolled material 2 is conveyed downstream by the conveying table 3.

  The side guide device 4 is disposed adjacent to the rolling mill 1 on the downstream side of the rolling mill 1, for example. The side guide device 4 may be arranged on the upstream side of the rolling mill 1. The side guide device 4 may be arranged on both the upstream side and the downstream side of the rolling mill 1. The side guide device 4 has a centering function and a vertical rolling function.

  The centering function is a function for guiding and guiding the rolled material 2 to the center of the conveying table 3 so that the rolled material 2 is conveyed along the center line of the conveying table 3. The vertical rolling function is a function of reducing unevenness in the width direction of the rolled material 2. Moreover, the width | variety of the rolling material 2 can also be made into a desired value with a vertical rolling function.

  The side guide device 4 includes guide devices 5 and 6. The guide devices 5 and 6 are arranged close to the rolling mill 1. The guide devices 5 and 6 are in contact with the rolled material 2 conveyed by the conveyance table 3 from the side. The guide device 5 is in contact with one end surface of the rolled material 2. The guide device 6 is disposed on the opposite side of the guide device 5 with the transport table 3 interposed therebetween. That is, guide devices 5 and 6 are provided on both sides of the transfer table 3. The guide device 6 contacts the other end surface of the rolled material 2.

  The guide devices 5 and 6 have a symmetrical configuration. Therefore, only the configuration of the guide device 5 will be described in detail below. Since the guide device 6 has the same configuration as the guide device 5, detailed description thereof is omitted.

The guide device 5 includes supports 7 and 8, a roller guide 9, and drive devices 10 and 11.
The support body 7 consists of a rod-shaped member, for example. The support 7 is disposed horizontally along the conveying direction of the rolled material 2.

  The roller guide 9 is a member that actually contacts the rolled material 2. The roller guide 9 is rotatably supported by the support body 7 so that the rotation axis faces the vertical direction. The guide device 5 includes a plurality of roller guides 9. In the present embodiment, as a simplest example, a case where two roller guides 9 are provided in the guide device 5 is shown. The guide device 5 may be provided with three or more roller guides 9. The plurality of roller guides 9 are arranged side by side along the conveying direction of the rolled material 2.

  The driving device 10 generates a driving force for rotating the roller guide 9. For example, the driving device 10 is provided for each roller guide 9 and is supported by the support 7. The driving device 10 rotates the roller guide 9 so that the surface of the roller guide 9 facing the rolled material 2 side moves in the same direction as the rolled material 2.

  The driving device 11 generates a driving force for moving the support 7. One end of the support 8 is connected to the center of the support 7. The driving device 11 moves the support 7 via the support 8. Specifically, the drive device 11 moves the support 7 horizontally so that the support 7 approaches and separates from the rolled material 2. As the support 7 moves, the roller guide 9 approaches the rolled material 2 and is separated from the rolled material 2.

  In the hot rolling line provided with the side guide device 4 having the above-described configuration, the plate-shaped rolled material 2 that has passed through the rolling mill 1 is transported to the position of the side guide device 4 by the transport table 3. When the rolled material 2 passes between the guide devices 5 and 6, centering and end surface smoothing are performed. Moreover, the rolling for making the rolling material 2 into a desired width is performed as needed.

  That is, the support 7 is driven by the driving device 11, and the position of the roller guide 9 of the guide device 5 and the position of the roller guide 9 of the guide device 6 are appropriately set. Further, the roller guide 9 is rotated by the driving device 10 in a direction corresponding to the conveying direction of the rolled material 2. The rolled material 2 passes between the guide devices 5 and 6 with one end surface contacting the roller guide 9 of the guide device 5 and the other end surface contacting the roller guide 9 of the guide device 6. Since both the centering of the rolled material 2 and the smoothing of the end surface can be performed by the side guide device 4, the transport distance of the rolled material 2 can be shortened. When reverse rolling is performed, the rolling pitch can be shortened and productivity can be improved.

  In addition, you may install the side guide apparatus 4 of the said structure in lines other than a hot rolling line.
