The invention provides a loop control method and device, terminal equipment and a computer readable storage medium. The method comprises the steps that when it is detected that a lower rolling machineis engaged with strip steel, the loop rising torque is applied to a loop, the loop feedback angle is obtained, the actual angular speed and the actual angular acceleration of the loop are calculatedaccording to the loop feedback angle, and whether the loop makes contact with the strip steel or not is judged on the basis of the preset contact judgment rule and the actual angular acceleration; when it is judged that the loop makes contact with the strip steel, the loop rising torque is removed, the loop detection tension is obtained, based on the constructed loop capacity height output variable integral function and the variable integral parameter determining rule, the loop capacity height output of the loop is dynamically adjusted according to the loop feedback angle, the actual angular speed and the loop detection tension; and loop falling is controlled. According to the scheme, through the variable integral function, the loop height output is dynamically controlled according to three indexes including the angle, the angular speed and the detection tension, and the problems about virtual loop steel stacking and narrow pulling due to too high loop rising and falling speed and theproblems about adjusting vibration and over adjustment can be solved.
