Method and device for determining cold continuous rolling strip thickness reduction dynamic rolling roller gap

The invention discloses a method and a device for determining a dynamic rolling roller gap for reducing the thickness of a cold continuous rolling strip, which are applied to the technical field of rolling, and the method for determining the dynamic rolling roller gap for reducing the thickness of the cold continuous rolling strip comprises the following steps: establishing a speed field of a dynamic rolling deformation area, and determining a strain speed field of the dynamic rolling deformation area based on the speed field; based on the relation between the deformation resistance of the cold continuous rolling strip and the thickness change of the cold continuous rolling strip in the dynamic rolling process, the rolling force of the dynamic rolling elastic deformation area is determined; based on the speed field and the strain speed field, the minimum value of a total power generic function at any moment in the rolling process is determined, and the rolling force of the dynamic rolling plastic deformation
