Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a running joint for joining a rear end of a preceding rolled material and a front end of a subsequent rolled material while traveling with the rolled material in a hot rolling facility.

[0002]

2. Description of the Related Art In a conventional hot rolling mill (hot strip mill), bar materials rolled by a rough rolling mill are separately supplied to a finishing mill to obtain a strip material having a desired thickness. . However, such means cannot uniformly roll the entire rolled material, easily cause defects at the ends (front end and rear end) of the rolled material, lowering the yield of the rolled material, and reducing the occurrence of biting / hip loss. Therefore, there was a problem that it was difficult to increase the rolling speed.

In order to solve such a problem, there has been proposed a rolled material joining apparatus as shown in FIG. 2 (Japanese Patent Laid-Open No. 7-323306). The rolled material joining apparatus shown in FIG. 1 is a rear end clamp device which can vertically move a carriage 1 running in a rolling direction and a rear end of a preceding rolled material 2 mounted on the carriage 1 and horizontally held. 3, a tip clamping device 5 for horizontally holding the leading end of a rolled material 4 mounted on the trolley 1 and horizontally, a lower surface of a rear end portion of the preceding rolled material 2 and a trailing rolled material 4
Processing device 6 for cutting the upper surface of the front end portion, reduction holding device 7 for holding the processed surface in a reduced state, and preceding rolled material 2
And a pressure welding device 8 for superimposing the processing surfaces of the succeeding rolled material 4 and compressing and joining them to substantially the same thickness as the rolled material. With this joining device, the rear end of the preceding rolled material 2 and the front end of the succeeding rolled material 4 can be joined while traveling with the rolled material, and can be joined in a short time with sufficient joining strength over the entire width of the rolled material. Thus, the joining portion can be processed almost uniformly with little unevenness of the joining portion, whereby the rolled material can be continuously supplied to the finishing mill.
Hereinafter, a joining device that joins the rolled materials while traveling is referred to as a “running joining device”.

[0004] However, the above-described traveling joining apparatus includes the bogie 1, the clamping devices 3, 5, the processing device 6, the pressing device 8 and the like located below the rolled material, so that the inclined guide 17 shown in FIG. And 18, the rolled materials 2 and 4 need to be lifted and joined, and even in the rolled material other than the joining portion, a useless movement of once lifting and lowering after passing through the joining device occurs, and the roller table positioned at the rolling height is generated. In order to avoid interference with the vehicle 19, the position of the trolley 1 is increased, so that the height of the apparatus as a whole is increased and the size is increased.

In order to solve the above-mentioned problems, there has been proposed a device in which a table roller for supporting a rolled material can be retracted in conjunction with the travel of a traveling joining device (for example, JP-A-4-367303, Kaihei 7-1007).

[0006]

Problems to be Solved by the Invention
As shown schematically in FIG. 3, the No. 3 apparatus is provided in a joining machine 20 for joining the leading rolled material 2 and the trailing rolled material 4 in a state where they are advancing, and the traveling range thereof. A plurality of movable table rollers 21 are provided, and the position of the traveling joining machine 20 is detected by a control unit (not shown), and the drive cylinders 22 are respectively operated via the respective solenoid valves of the control unit. The roller 21 is sequentially moved up and down to avoid collision with the joining machine 20. However, in this apparatus, the movable table roller 21
Of the solenoid valve for raising and lowering the movable table roller 21 is problematic in this control, and there is a possibility that the joining machine 20 and the movable table roller 21 may collide with each other. In addition, there is a problem that the amount of oil in each of the drive cylinders 22 becomes large, the hydraulic device becomes large, and the hydraulic device is constantly operated, so that its power is lost.

On the other hand, the apparatus disclosed in Japanese Patent Application Laid-Open No. Hei 7-1007 has a plurality of table rollers 23 which lift and lower within the moving range of the joining machine 20 to support a plate material, as schematically shown in FIG. A guide roller 24 provided on a supporting member for supporting the table rollers, and balance cylinders 25 for urging the respective table rollers 23 upward, and the head sides of the respective balance cylinders 25 are connected and sealed by piping 26. With the traveling of the welding machine 20, the guide rails 27 provided on the welding machine 20 sequentially lower the table rollers 23 below the self-propelled welding machine 20 via the respective guide rollers 24 abutting on the guide rails 27, Collisions with the joining machine 20 are reliably avoided. However, in this apparatus, since the table roller 23 is lowered while the guide rail 27 and the guide roller 24 are in contact with each other, when the joining machine 20 is moved at a high speed, a large lateral load acts on the guide roller 24 and the balance cylinder 25, There is a problem that the guide roller 24 is easily damaged and oil leaks from the balance cylinder 25 are likely to occur, and the accumulator 28 that supplies pressure oil to the head side of each balance cylinder 25 becomes large.

The present invention has been made to solve the above-mentioned problems. In other words, there is no need for a large hydraulic source, hydraulic equipment, and hydraulic piping, and a rolled material support device that is easy to control is provided, so that the height of the rolled material to be conveyed and the height of the rolled material after joining are almost the same. It is an object of the present invention to provide a running joint device capable of performing the following.

[0009]
