Shot blasting machine: standards of steel shot used

What are the working principles of steel shot used in shot blasting machines?

1. Shot blasting and sand blasting are both types of surface treatment, but this does not mean that only castings are subjected to shot blasting. 2. The main purpose of sand blasting is to remove rust and scale from the surface. For example, for parts after heat treatment, the effect and performance of the shot blasting machine is higher: not only are rust and scale removed, but also the surface roughness is improved, burrs on the parts are removed, internal stresses of the parts are eliminated, the deformation of parts after heat treatment is reduced, and the wear resistance and compressive strength of the surface of the parts are improved. 3. There are many shot blasting processes, such as: casting, forging, surface treatment of parts after machining, surface treatment of parts after heat treatment, etc. 4. Sand blasting is mainly done by people, while shot blasting is mainly automated or semi-automated. 5. The steel and iron shot used in shot blasting is not actually shot. To be precise, it is thin steel wire or small steel rod.

Some professions are also different. For example, the shot blasting machine in shipbuilding uses real steel shot, while the sand blasting machine uses metal ore sand.

1. Tablets and sand. Granules are usually spherical particles without edges. Such as wire cutting shot, etc.; Sand refers to angular sand particles such as brown corundum, white corundum, river sand, etc.

2. Spray and throw. Spraying uses compressed air as energy to spray sand or shot onto the surface of a material to remove material and give it a certain roughness. Shot blasting is a method of using the centrifugal force generated by the high-speed movement of the shot to impact the surface of a material to remove material and give it a certain roughness.
