In recent years, multiple long steel strips for hot rolling have been sequentially joined in order to minimize the order yield due to non-uniform structure due to defects and poor surface quality, etc. A so-called continuous hot rolling method of continuously performing hot rolling at a predetermined speed has been attempted.

ーテーブルが配設されている。Therefore, as a traveling joining device in the joining step, a rear end clamping device for a preceding rolled sheet material and a trailing end sheet material, as disclosed in Japanese Patent Application Laid-Open No. Hei 4-30001, are used. In addition to using a tip end clamping device which is capable of swinging and which can be independently driven in the supply direction of the rolled plate material and in the opposite supply direction, as disclosed in Japanese Patent Publication No. 62-53242, A roller table is provided on the traveling path of the traveling joining device, in which each roller is installed so as to be able to descend and retreat and ascend back from the rolled plate material pass line.

From the bottom to the top, and after passing through it, run while sequentially raising and returning each roller to the rolling steel pass line, clamp the rear end of the preceding rolling steel and the front end of the following rolling steel. After matching
These were joined.

と平行にした後、接合しなければならない。The rear end portion of the steel material for leading rolling and the front end portion of the steel material for trailing rolling that have been cut have the flat shape of the steel material itself before being clamped by the clamp device of the traveling joining device. Changes, meandering and camber often occur, and when it becomes harder, the cutting end face is rotated by driving a clamping device that clamps the leading end of the subsequent rolling steel material to abut the cutting end face of each end for joining. The position must be corrected so that it is parallel to the cut end face of the rear end of the preceding rolling steel that cannot be corrected, and then joined.

傍に無く不可能である。However, since the table rolls on the entry side and the exit side of the traveling joining device are always on the rolling steel pass line, both the preceding rolling steel and the following rolling steel are conveyed in a straight line. For this reason, as described above, it is impossible to correct the position of the cut end surface of the leading end portion of the subsequent rolling steel material because there is no portion in the vicinity of the leading end portion of the subsequent rolling steel material that absorbs the corrected movement amount.

移動量を吸収することが公知である。[0008] In addition, there is no function of buffering fluctuations in the rolling speed of the steel material for advance rolling. In order to solve this problem, a predetermined length near the joining portion of the steel for subsequent rolling is formed by forming a loop as in a strip welding method disclosed in Japanese Patent Publication Nos. 52-17510 and 51-21603. A rising loop is formed once by abutting and rising of the mechanism, and then the loop forming mechanism is immediately lowered, and the remaining loop absorbs a correction movement amount of the cutting end surface position of the leading end of the subsequent rolling steel material. Is known.

It is large and complicated. Also, while the steel material is abutted and raised by the looper roll of the loop forming mechanism, the abutted steel material portion moves while undergoing large-scale plastic deformation, so that a crack is generated or correction by a correction device is required. You will have various problems.

成方法は断念せざるをえなかった。When a rising loop is formed and the loop forming mechanism is immediately lowered to form a remaining loop,
It is necessary to control the descending overspeed of the looper, which has a loop deformation margin enough to absorb the correction movement amount of the cutting end surface position of the leading end portion of the subsequent rolling steel material. Because
Exceeding the loop deformation allowance to absorb the corrected movement amount
This is because a steep drop phenomenon occurs and damages the steel material and the looper roll. However, in reality, it is very difficult to grasp in advance the amount of correction movement of the cutting end face position of the leading end of the succeeding rolling steel in consideration of buffering against fluctuations in the rolling speed of the preceding rolling steel. However, the method of forming the ascending loop had to be abandoned.

According to the present invention, as described above, the rollers 5A that interfere with each other during the forward traveling of the traveling joining device 4 are sequentially lowered and retracted from the rolled plate material pass line, and are maintained after the forward traveling. The hanging loop DL of the succeeding rolled sheet material 2 on the roller 5AD
Gently forming, and a rear end cut surface 1A of the preceding rolled plate material 1 and a front end cut surface 2A of the subsequent rolled plate material 2
Therefore, the correction of the position of the cutting end face 2A at the leading end of the succeeding rolled plate material 2 at the time of the butting requires that the rolling speed of the preceding rolling material 1 fluctuates even if the corrected movement amount CR is large. Even if there is, it can be sufficiently absorbed by the torsional deformation FR of the loop DL on each of the rollers 5AD that are retracted. In addition, since it is the hanging loop DL, no special support mechanism and control mechanism are required in addition to the roller 5AD, and a pinch roll PR capable of variable speed control for hanging loop formation may be simply provided behind the traveling joining device. .

According to the above configuration, when joining the rear end portion of the preceding rolling material and the front end portion of the subsequent rolling material, the correction of the cutting end surface position of the leading end portion of the subsequent rolling steel material at the time of abutting is performed by correcting the Even if the amount of movement is large, and even if there is a change in the rolling speed of the steel material for preceding rolling, it can be sufficiently absorbed by the torsional deformation of the loop on each of the rollers retracted. In addition, since it is a hanging loop, no special supporting mechanism and control mechanism other than the rollers are required, and a pinch roll capable of variably controlling the speed for forming the hanging loop may be provided behind the traveling joining device.
