Steel balls and steel grit
produced by the decomposition method grinding, cleaning the surface with a
sharp-edged, angular structure, enable done roughening and cutting process in
the most effective manner.
Steel grit is used in many
sectors. These include casting, plating, ship building, dam maintenance,
granite production and various manufacturing industries are became prevail.
Some of the uses areas of Steel shots and grits are removal of sand, deburring,
oxide removal, surface preparation, stress relieved, stone surface treatment,
has cut granite blocks…etc.
For the production of steel
smelted steel grit is transported in the direction of the required alloy
composition and poured into a water jet. Colliding with water metals solidify
as spheres. Solidifying these spheres, giving water before annealing ensuring
the formation of martensite. This structure is very hard and brittle. Fragile
in these spheres roll crusher broken, sharp edges and corners provide a way to
arrive. Then the resulting tempered over-tensile is eliminated. So awesome
abrasive, easily unbreakable, durable material is produced.
