The purpose of shot blasting:
For castings, shot blasting can be used to: reinforce surface quality, finish casting surfaces, remove casting sand and surface foreign objects, shovel cuts, quilts and burrs, as well as sanding and finishing castings. Surface and surface concealment of surface defects.
The advantages of shot blasting are:
1 According to the purpose of steel, the specified descaling level can be cleaned and a uniform finished surface can be obtained;
2 closed operation, no dust flying;
3Applicable to steel plates of 5mm or more, wide flat steel and section steel;
4 fast, high efficiency and stable quality.
The thickness of the abrasive, the pressure of the compressed air (ie, the linear velocity of the projectile), and the time of the shot blast can be adjusted to obtain different shot blast finishes and cleaning qualities.
What is shot blasting:
The shot blasting treatment is to use the centrifugal force of the impeller on the throwing head of the shot blasting machine to rotate at a high speed, and the abrasive is shot at a high linear velocity on the surface of the treated steel to produce a striking and grinding action to remove the scale on the surface of the steel. And rust and produce a certain roughness. Shot blasting is highly efficient and can be carried out in a sealed environment.
Widely used in the workshop steel pretreatment line.
Shot blasting is carried out under sealed conditions, with a dust suction device and automatic painting, which is an efficient automated assembly line operation.
