High-intensity steel reeling machine wrapper roller step control method based on pressure deviation

The invention belongs to the field of steel rolling control and discloses a high-intensity steel reeling machine wrapper roller step control method based on pressure deviation. When the head portion of band steel reaches a wrapper roller, according to the pressure deviation when the wrapper roller bites the steel, the step position value of the wrapper roller is selected and is equal to the sum of the wrapper roller original step position value and an additional bounce amount delta X, the delta X is (0.0-1.0)*h, and h is the thickness of the band steel. The method eliminates the major quality hidden danger of the band steel surface impression caused by too large band steel head portion pressure under action of the wrapper roller when the reeling wrapper roller steps, improves the product yield, meets the requirements of a next procedure, and obtains good benefits.
