What's shotblasting and its applications
- Nov 13, 2017 -
The role of steel shot, acting on the workpiece surface, make the surface of the workpiece as part of the coarse degree, makes the artifact as beautiful, or change the workpiece welding tensile stress to compressive stress, improve the service life of the workpiece.Can be used in most areas of mechanical production.
In the metal processing industry, shot blasting machine is a kind of common metal surface treatment equipment, is the use of shot blasting machine, the steel shot abrasive products such as high-speed into the surface of metal, under the action of force, will be a series of metal surface cleaning, to meet the standard requirements.
Steel shot blasting machine is used to complete the entire process, known as shot blasting, blasting is the use of high-speed rotating impeller pills for the small steel or iron casting out high speed impact parts surface, so it can remove the oxide layer on the surface of the parts.Pills for steel or iron, at the same time high speed impact parts surface, cause the deformation of lattice distortion on the surface of the parts, the surface hardness is higher, it is a kind of method to clean the surface of the metal parts, casting surface blasting are commonly used to clean up, or to strengthen the part surface.
In the process of the use of steel shot, steel grit hardness property determines the service life of steel shot, steel grit is proportional to the hardness and clean up the speed, the higher the hardness, cleaning speed is fast, the consumption of steel shot will play, life is short, the manufacturing process of steel shot determines the size of the steel pill, the bigger the diameter of cleaned up the surface roughness is higher, but the efficiency is high, relative to the wear of steel pill is bigger also.
