Control method and device for reducing unilateral protrusion in steel belt coiling process

The invention discloses a control method for reducing unilateral protrusion in the steel belt coiling process, belongs to the technical field of steel belt coiling, and solves the technical problem that the unilateral protrusion is too large in the current steel belt coiling process. The method comprises the steps that the pressure of side guide plates on the two sides and the pressure of the two sides of a steel belt are obtained respectively, and the pressure difference of the pressure on the two sides is calculated; and the position of the steel belt before entering the coiling machine is adjusted according to the pressure difference, so that the single-edge side bulge of the steel belt in the coiling process is reduced. The invention further discloses a control device for reducing the single-side protrusion in the steel belt coiling process. By comparing the pressure of the side guide plates on the two sides and the pressure of the two sides of the steel belt, the deviation trend of the steel belt is judg
