Steel abrasives are steel particles that are used as abrasive or peening media.They are usually available in two different shapes (shot and grit) that address different industrial applications.
Steel grit characterizes grains with a predominantly angular shape. These grains are obtained by crushing steel shot, therefore they exhibit sharp edges and broken sections. Harder than steel shot, it is also available in different sizes and hardnesses..
Steel shot and grit address numerous sectors since cleaning, surface preparation or shot peening applications are used by many industries as a part of their construction, renovation or repair processes. The main industrial sectors employing steel abrasives are:
1.Automotive industry
2.Construction
3.Metallurgy
4.Petrochemical industry
Smelting:Using Electric arc furance smelting,steel components can be adjusted to reduce the content of harmful elemental such as sulfur,phosphorus .
Refining:Using refining furnace to refine molten steel,improving the purity of molten steel,then the steel shot can get better material.
Granulation:High speed centrifugal casting forming,effective control the forming quality and reduce physical defects.
Selection:To separate hollow and defective particles effectively, to improve the density of steel shot.
Quenching:Using secondary quenching to refine grains and make the product more compact internal microstructure to enhance the toughness.
Tempering:To refine the internal organization further to reach the requirement of different hardness,to make it's uniformity of the organization and hardness best by precise temperature and time control.
Broken:Unique crushing prcess make the steel grit has better fullness and angularity,to reduce the internal cracks of the steel grit grain as well.
Fine Sieve:To control particle size Precesion,make the products meet the American SAE-J444 standard.
