The invention relates to a method for stabilizing a strip steel during a strip steel production process. According to the method, both sides of the strip steel are symmetrically provided with a blower with an opening on a side; the two blowers are respectively connected with a gas transmission pipeline; the gas transmission pipelines are respectively provided with a valve; a guide block is arranged on the middle of the opening side of the blower, two nozzles are formed on the side of the blower, wherein the side of the blower is relative to the strip steel, the two nozzles comprise an upper nozzle and a lower nozzle, and the two nozzles concurrently jet gas to the strip steel; the blocks are respectively provided with a sensor; the two sensors concurrently detect the distance between the senor and the strip steel, wherein the normal state is that: the distance between one senor and the strip steel is equal to the distance between the other senor and the strip steel; when the unequal condition is generated, the apertures of the control valves on the gas transmission pipelines of the two blowers are concurrently adjusted, such that the pressure generated by the blowers on both sides of the strip steel is decreased or increased until the distance between one senor and the strip steel is equal to the distance between the other senor and the strip steel so as to prevent the strip steel from buffeting. According to the present invention, the non-contact manner is adopted to prevent the strip steel from buffeting, such that the damage on the strip steel surface due to the contact vibration suppression is avoided, the stability effect of the existing cushion method is improved, and the high requirements of the surface quality of the strip steel are met.
