BACKGROUND OF THE INVENTION
The present invention relates to a rolling facility provided with a running joining device that joins a trailing end of a preceding rolled material and a leading end of a subsequent rolled material while traveling together with the rolled material.
[0002]
[Prior art]
In a conventional hot rolling facility (hot strip mill), a bar material rolled by a roughing mill is supplied to a finishing mill one by one to obtain a strip material having a desired plate thickness. However, with such means, the entire rolled material cannot be uniformly rolled, and the end portions (front end portion and rear end portion) of the rolled material are likely to be defective. Therefore, there is a problem that it is difficult to increase the rolling speed.
[0003]
In order to solve such a problem, the inventors of the present invention, as illustrated in FIG. 4, horizontally arranges a carriage 3 that travels in the rolling direction and a rear end portion of the rolling material 1 that is attached to and precedes the carriage. A rear end clamping device 4 that can be moved up and down by being sandwiched between the front end, a front end clamping device 5 that horizontally attaches a front end of the rolled material 2 that is mounted on the carriage, and a lower surface of the rear end of the preceding rolled material 1 And a processing device 6 for cutting the upper surface of the tip of the subsequent rolled material 2, a reduction holding device 7 for maintaining the processed surface in a reduced state, and the processed surfaces of the preceding rolled material 1 and the subsequent rolled material 2 are overlapped. Invented and filed a running joint device 10 including a pressure welding device 8 that presses and joins the rolled material to approximately the same thickness (Japanese Patent Application Laid-Open No. 7-323306, Japanese Patent Application No. 7-55488, etc.) .
[0004]
With this joining device, the trailing end of the preceding rolled material and the leading end of the succeeding rolled material can be joined while traveling together with the rolled material, and the entire width of the rolled material can be joined with sufficient joining strength in a short time. The joints can be processed almost uniformly with little unevenness in the joints, whereby the rolled material can be continuously supplied to the finishing mill. Hereinafter, a joining device that joins the rolled material while traveling is referred to as a “running joining device”.
[0005]
[Problems to be solved by the invention]
In the rolling line provided with the above-mentioned running joining device, for example, it is necessary to join the preceding rolled material and the following rolled material while traveling with the running joining device every about 90 seconds. The process is repeated until the joining of the rods is completed, and another rod needs to be joined again after a pause of several minutes.
[0006]
Therefore, the following problems occur when the running joint device stops due to failure or maintenance.
(1) When the continuous rolling is stopped and the conventional batch rolling is changed, the production amount is greatly reduced and the yield is deteriorated. In particular, when the running joint device fails, the running joint device is on the rolling line (inline), so the rolling material passes under it, and maintenance is difficult, and recovery work takes time. .
(2) When the rolling itself is completely stopped (line stop), the maintenance is relatively easy, but the production itself is completely stopped.
[0007]
The present invention has been made to solve such problems. That is, the objective of this invention is providing the rolling equipment provided with the running joining apparatus which can maintain a running joining apparatus easily, without reducing the productivity of a rolling line.
