Carbide tungsten steel boron carbide single and double air inlet gun head

Shot blasting is the use of high-speed rotating impeller to throw small steel shot or small iron shot out and impact the surface of parts at high speed, so it can remove the oxide layer on the surface of the whole machine. At the same time, steel shot or iron shot impacts the part surface at high speed, resulting in lattice distortion and deformation on the part surface and increasing the surface hardness. It is a way to clear the part surface. Shot blasting is often used to clean the casting surface or strengthen the part surface.

Generally, shot blasting is used for regular shapes. How many throwing heads are about the same height, which has high efficiency and small infection. Shot blasting and sand blasting are widely used in repair and shipbuilding industry. However, both shot blasting and sand blasting are the application of compressed air. Of course, it is not shot blasting that requires a high-speed rotating impeller. In general, shot blasting (small steel shot) is mostly used in steel plate pretreatment (rust removal before coating); Sand blasting (mineral sand used in repair and shipbuilding) is mostly used in formed ships or sections. Its function is to remove the old paint and rust on the steel plate and paint it again. In the repair and shipbuilding industry, the important role of shot blasting and sand blasting is to increase the adhesion of steel plate coating paint.
