Straightening equipment control method and device, straightening equipment and readable storage medium

The invention discloses a control method and device of straightening equipment, the straightening equipment and a readable storage medium. The straightening equipment comprises a rough straightening machine and a fine straightening machine, strip steel sequentially passes through the rough straightening machine and the fine straightening machine, and the control method comprises the steps that the linear speed of a straightening roll of the rough straightening machine is controlled to run at a first speed; the linear speed of a straightening roll of the fine straightening machine is controlled to run at a second speed, the speed ratio of the first speed to the second speed is n, and n is larger than or equal to 0.98 and smaller than 1; driving torque of rotation of a straightening roll of the fine straightening machine is obtained; and controlling the roll gap of the fine straightening machine according to the driving torque and the preset maximum torque. According to the control method, device and equipment
