Steel shot preparing method and shot blasting technology applying steel shots

Abstract

The invention discloses a steel shot preparing method, and relates to the technical field. A steel shot comprises chemical components including, by mass percent, 0.65%-0.78% of C, 0.22%-0.25% of Si, 0.14%-0.16% of W, 0.55%-0.75% of Mn, 0.49%-0.58% of Ti, 0.11%-0.18% of Al, 0.02%-0.07% of Nb, and the balance Fe. The invention further discloses a shot blasting technology. The shot blasting technology comprises the following steps that S1, degreasing, washing and drying are conducted on a workpiece which is about to be subjected to shot blasting; S2, after shot blasting line equipment is debugged, steel shots are added in the shot blasting line equipment, the workpiece is arranged in a shot blasting chamber, the position of the workpiece is adjusted, a nozzle of an impeller head faces the workpiece, and then shot blasting treatment is conducted; S3, after shot blasting treatment is finished, shot particles on the surface of the workpiece are removed; and S4, the workpiece obtained after shot blasting treatment is checked. According to the steel shot preparing method and the shot blasting technology, the steel shot hardness and deformation resisting capability are effectively improved,dust is small, the service life is longer, the shot blasting technology efficiency is effectively improved, and meanwhile the cost of the shot blasting technology is reduced.

Description

technical field [0001] The invention relates to the technical field of shot blasting technology, in particular to a method for preparing steel shot and a shot blasting technology using the steel shot. 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 shots of some shot blasting machines are generally quartz sand and steel shot.

Problems solved by technology

[0003] The shots of some shot blasting machines are generally quartz sand and steel shot. Although the price of quartz sand is low, it is brittle and produces a lot of dust, which affects the shot blasting effect. Although the general steel shot is not brittle, it is easy to deform. Short service life and low cost performance, which will increase the cost of the shot blasting process
