Steel strip descaling method

The invention belongs to the field of steel strip production, and particularly relates to an environment-friendly thorough method for removing oxide, namely scale, on the surface of a steel strip with a fine condition. The method includes the steps: A, feeding the steel strip into a scale breaking device to break the scale on the surface of the steel strip; B, feeding the steel strip treated in the step A into a sand blaster, blasting steel shots, high-pressure water and high-pressure air to the surface of the steel strip, and further breaking and washing the scale on the surface of the steel strip; C, feeding the steel strip treated in the step B into a brush roll device, polishing and brushing the surface of the steel strip and further removing residual scale and smoothening the surface of the steel strip; D, feeding the steel strip treated in the step C into a strip brush device and brushing off cuttings and remaining scale on the upper surface of the steel strip after polishing and brushing; E, feeding the steel strip treated in the step D into a cleaning device and washing the surface of the steel strip with clear water; and F, rolling the cleaned steel strip by the aid of a gripping roll.
