Problems solved by technology
During the strip threading process, if the looper control of the strip steel is abnormal and cannot be controlled normally, the strip steel will lose tension in the frame, which will easily cause the strip steel to deviate and break, resulting in scrap steel

The embodiment of the invention provides a control method of strip steel finish rolling equipment, the strip steel finish rolling equipment comprises at least two finishing mills arranged in sequence, a loop mechanism is arranged between every two adjacent finishing mills, the loop mechanisms support strip steel to form strip steel loops, and the method comprises the steps that the actual working angle of the strip steel loops is obtained; on the basis of the actual working angle and the preset working angle of the strip steel loop, the torque coefficient of the strip steel loop is determined, and the product of the torque coefficient and the preset tension torque of the strip steel loop serves as the target tension torque of the strip steel loop; according to the target tension torque of the strip steel loop, target output force of a loop mechanism is determined, and the target output force is used for adjusting the working angle of the strip steel loop; and returning to execute the step of acquiring the actual working angle of the strip steel loop until the working angle of the strip steel loop is adjusted to the preset working angle. The stability of adjusting the angle of the strip steel loop can be effectively improved, and the strip steel can be prevented from losing tension and deviating to a certain extent.
Description
technical field [0001] The present application relates to the technical field of steel rolling, in particular, to a control method, device and computer equipment for strip steel finish rolling equipment. Background technique [0002] In the strip finish rolling process, since the strip tends to deviate in the stand, the stable control of the strip looper plays an important role in thin-gauge rolling. During the strip threading process, if the looper control of the strip steel is abnormal, and the looping control cannot be performed normally, the strip steel will lose tension in the frame, which will easily cause the strip steel to deviate and break, resulting in scrap steel. [0003] Therefore, those skilled in the art are in urgent need of a control method for strip finishing equipment to stably control the strip looper. Contents of the invention [0004] The embodiments of the present application provide a control method, device and computer equipment for strip finishin...
