Key control parameters for Dalian shot blasting processing

Dalian shot blasting is a machining process that acts on metal surfaces, similar to sandblasting and shot peening. It is achieved by throwing spherical projectile particles onto the surface of a metal workpiece, relying on strong impact force to change the surface roughness of the workpiece, and also improving the adhesion of the subsequent paint film of the workpiece, thereby improving the mechanical performance of the workpiece. Shot blasting is almost used in most fields of machinery, such as shipbuilding, automotive parts, aircraft components, gun tank surfaces, bridges, steel structures, glass, steel plate profiles, anti-corrosion of pipeline inner and outer walls, and even road surfaces.

The steel shot and iron shot used for shot blasting are actually not real shots. To be precise, they are small steel wires or rods that only look like balls after being used for a period of time. The so-called sandblasting sand, to put it bluntly, is just river sand, which is no different from building sand. It is only the sand used for sandblasting that has been sieved, contains less mud, and has a specified particle size. Of course, there are also differences in some industries, such as the shipbuilding industry where real steel shot is used for shot blasting and metal mineral sand (not river sand quartz sand) is used for sandblasting.

Key control parameters for Dalian shot blasting processing

The shot blasting treatment process and equipment control the surface condition after treatment through the following three parameters according to the different surfaces that need to be treated:

1. Choose the size and shape of the steel shot, which determines the surface roughness after treatment.

2. The walking speed of the shot blasting equipment determines the depth of treatment.

3. The flow rate of steel shot determines the efficiency of shot blasting.

Shot blasting is the process of using an electric motor to drive the impeller body to rotate, and using centrifugal force to throw balls (such as steel shot, steel sand, cutting shot, stainless steel shot, etc.) with a diameter of 0 to 0 onto the surface of the workpiece, achieving a certain roughness on the surface of the workpiece, making the workpiece more elegant, or changing the welding tensile stress of the workpiece to compressive stress, thereby improving the service life of the workpiece. It is almost used in most fields of machinery, such as repairing ships, automotive components, aircraft components, gun tank surfaces, bridges, steel structures, glass, steel plates, pipelines, and so on.

During the operation of the shot blasting machine, the particle size and shape of the shot material are controlled and selected, as well as the walking speed of the machine is adjusted and set to control the shot flow rate of the shot material, obtain different shot intensities, and achieve different surface treatment effects. The shot blasting process and equipment control the surface condition after treatment through three parameters based on the different surfaces that need to be treated. Select the size and shape of the shot material; The walking speed of the equipment; The flow rate of the pellets.
