Shot blasting treatment method for rust removal and rust prevention of steel plate

Abstract

The invention discloses a shot blasting treatment method for rust removal and rust prevention of a steel plate, and relates to the field of shot blasting. The shot blasting treatment method comprisesthe steps of S1, measuring the thickness of the steel plate; S2, carrying out degreasing treatment; S3, carrying out water washing, draining and drying; S4, carrying out shot blasting on the steel plate, adjusting cooperation of a current of a shot blasting machine and time according to the thickness, measured in the S1, of the steel plate, if the thickness of the steel plate is smaller than 3 mm,prohibiting treatment; if the thickness of the steel plate is 3 mm to 3.5 mm, controlling the current to be 15 A to 20 A, and controlling the shot blasting time to be 60 s to 70 s; if the thickness of the steel plate is 3.5 mm to 4 mm, controlling the current to be 15 A to 20 A, and controlling the shot blasting time to be 70 s to 90 s; and if the thickness of the steel plate is larger than 4 mm,controlling the current to be 20 A to 30 A, and controlling the shot blasting time to be 80 s to 100 s; S5, cleaning shots on the surface of a workpiece through a rolling brush or scraper; S6, checking the workpiece; and S7, spraying antirust paint to the surface of the qualified steel plate. According to the shot blasting treatment method, the current and time during shot blasting treatment areadjusted according to the thickness of the steel plate, resources are saved while the shot blasting effect is guaranteed, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of shot blasting technology, in particular to a shot blasting treatment method for rust removal and antirust of steel plates. Background technique [0002] Shot blasting is the name of a mechanical surface treatment process, similar to sandblasting and shot peening. The principle is to use a motor to drive the impeller body to rotate, and rely on centrifugal force to throw the balls to the surface of the workpiece, so that the surface of the workpiece reaches A certain roughness can make the workpiece more beautiful, or change the welding tensile stress of the workpiece to compressive stress, so as to improve the service life of the workpiece. Almost used in most fields of machinery, such as ship repairing, auto parts, aircraft parts, gun tank surfaces, bridges, steel structures, glass, steel pipes, etc. [0003] The steel plate is a material that is used in almost every mechanical field. When the steel pla...

AI Technical Summary

Problems solved by technology

[0003] The steel plate is a material that is used in almost every mechanical field. When the steel plate is shot blasted, because the thickness of the steel plate is different, the uniform shot blasting process will cause serious deformation of some steel plates, while the shot blasting of other steel plates will cause serious deformation. The pill has not yet achieved the desired effect
