Application of steel shot and steel grit in steel surface treatment process

　　In the steel surface treatment process, a high-speed rotating impeller is used to throw steel shot, steel sand or iron shot out and hit the surface of the part at high speed to remove the oxide layer on the surface of the part. At the same time, steel shot or iron shot hits the surface of the part at high speed, causing the crystal lattice on the surface of the part to distort and deform, increasing the surface hardness. Shot blasting is a method to strengthen the surface of parts. In addition, it also has the functions of polishing and deburring. Shot blasting is often used to clean the surface of castings or parts that require surface strengthening. Shot blasting cannot be used for surface treatment of thin parts with small thickness.

　　Generally, steel shot and steel grit have regular shapes, and several shot heads are thrown together, up, down, left and right, with high efficiency and little pollution.

　　Both steel shot and steel grit can clean and decontaminate the workpiece. The purpose is to prepare for the next process, that is, to ensure the roughness requirements of the next process, and sometimes to ensure surface consistency. Steel shot is used to The workpiece has a strengthening effect, but the steel grit is not obvious.

　　Steel shot treatment is used in almost all fields of machinery, such as shipbuilding, auto parts, aircraft parts, gun and tank surfaces, bridges, steel structures, steel plates, pipes, etc.
