I.Technical characteristics

High hardness and wear resistance

The hardness of bearing steel grit reaches HRC 46-50, which is 1.5 times that of ordinary cast steel grit, and its service life is prolonged by 30%-50%.

Low dust emission

The optimization of production process can reduce the dust production by 20%-30%, and the emission concentration can be reduced to below 10 mg/m after the dust removal system is equipped.

Recycling of resources

The recycling rate of waste bearings is over 90%, and producing 1 ton of steel grit can save 1.2 tons of iron ore and reduce the production cost by 15%-25%.

II.The application field

surface treatment

It is used for ship derusting, steel structure anticorrosion and automobile parts polishing, and the cleaning efficiency is 20%-30% higher than that of ordinary steel grit.

Shot peening strengthening

In high-strength steel parts such as aero-engine blades and wind power gear boxes, the fatigue life can be increased by 1.5-2 times.

Casting sand cleaning

It is suitable for precise sand cleaning of complex castings (such as engine block), and the surface roughness can reach Ra 1.6 μ m..
