What's shotblasting and its applications-2

Steel shot cleared surface roughness is higher, the greater the diameter but cleaning efficiency is high;And irregular shape of the steel grit and steel cut wire shot cleaning efficiency than the spherical pellet is higher, but the surface roughness is high also.
When choosing steel shot size, under the premise that meet the requirements of surface roughness, choose larger steel shot, as far as possible in order to improve the cleaning efficiency.
Choose the standard of steel shot, basically be to see you to clean up the workpiece, non-ferrous metal general selection pills for aluminum or stainless steel.Ordinary steel, welding, casting, steel and other steel shot.
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.
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.
