The invention discloses a method for reducing the transverse deviation of strip steel. The method is applied in a continuous annealing furnace zone deviation correcting system. The method includes the following steps: based on specification information and initial strip shape information of the strip steel, initial roller shape information of a furnace roller and heat treatment process information, building a dynamic operation simulation model of the strip steel; based on the dynamic operation simulation model, obtaining a deviation orbital equation corresponding to the strip steel; after the strip steel enters a continuous annealing furnace zone, based on the deviation orbital equation, correcting the transverse deviation of the strip steel. The method can improve the stability of the strip steel in operation of the furnace zone, and reduces the transverse deviation of strip steel in the furnace zone in dynamic specification change. At the same time, the invention further discloses the continuous annealing f
