ックされる検出信号を加算する加算器である。Problems with the Conventional Technology Conventionally, the winding machine in a hot strip mill is controlled by speed control until just before the tip of the steel plate is wound around the winding machine, and after winding, current control is performed while finishing and final stands are controlled. Winding was performed by limiting the speed using a speed limiter that corresponded to a lead speed that was about 5 to 10% higher than the speed.

制御を速度制御から電流制御に切換える必要があり、こ

ランスがくずれ、加速トルクが生じて鋼板の巻取り速度
が上昇する場合がある。When performing winding noise i1i control using such a conventional method, it is necessary to switch the control of the nine winders from speed control to current control when the tip of the steel sheet wraps around the winder. If it is too late, excessive tension will occur due to a delay in the speed limiter, and on the other hand, if the switching timing is delayed, the load current will increase due to winding up to t during speed control, and excessive tension will also occur. As a result, the width of the plate near the exit side of the final finishing stand shrinks, resulting in so-called necking. In addition, if the tail end of the steel plate passes through the final finishing stand and the backward tension from the pinch roll or hot run table is insufficient, the winding machine loses its tension balance due to current control, which generates acceleration torque and reduces the winding speed of the steel plate. It may rise.

タツキを生じて耳折れ疵を発生させたりする。When this speed fluctuation occurs, it gives a negative influence to the winding temperature control by the hot run spray, and also causes flapping when winding the tail end of the steel plate, resulting in edge breakage.

制御する巻取り機の張力制御装置が開示されている。In order to solve the problem described in E, JP-A-56-122755
In the first publication, the current of the winding machine is controlled and the speed of the pinch roll is controlled before the rear end of the steel plate passes through the final finishing stand, and the winding machine is controlled after the rear end of the steel plate passes through the final finishing stand. A tension control device for a winder that controls speed and current controls pinch low μ is disclosed.

御のみでは鋼板の張力を一定に保つことはできない。When this winder tension control device is used, the tension of the steel plate after the rear end of the steel plate passes through the final finishing stand can be stabilized, but it is necessary to switch the winder control from current control to speed control. If this switching timing shift V occurs, the steel plate tension will also fluctuate. Furthermore, since two systems of control circuits are required, the circuit appears to be complex. Furthermore, after the rear end of the steel plate passes through the final finishing stand, the tail end of the horizontal plate tends to flap, and when it comes into contact with the side guide, excessive tension is generated due to frictional force. The tension in the steel plate cannot be kept constant just by controlling the current of the pinch rolls.

耳折れ疵等の発生も防１ヒできる。First of all, since it is not necessary to completely switch the control at the time when the tip of the steel plate is wound around the winder, generation of excessive tension due to a shift in switching timing can be prevented, and necking of the tip of the steel plate can be prevented. In addition, after the tail end of the steel plate is removed, the winding speed will fluctuate in the conventional method because the rear tension rapidly decreases, but with the method of the present invention, the winding speed is stable because the speed is constantly controlled. You can wind it up or build it up. Furthermore, if the rear tension is insufficient after the tail end of the steel plate passes through the final finishing stand, the winding speed increases by L in the conventional method due to current control, but the method of the present invention allows winding at a stable speed. Furthermore, even if the tail end of the steel plate comes into contact with the I side guide or the like, it is possible to continue winding with stable tension without generating excessive tension. Therefore, by using the method of the present invention, it is possible to reduce the disturbance of speed fluctuations caused by the hot run spray on the winding temperature change control, and improve the tail end stopping accuracy, thereby preventing the occurrence of edge breakage etc. due to fluttering of the steel plate tail end. Can defend against 1 hit.
