Cheap Aluminium Oxide Blasting Grit Suppliers USA

Because of the organic matter (dextrin, etc.) added during the formation of the 80 grit aluminum oxide grinding wheel, the oxidation atmosphere in the kiln is weak, the binder gradually melts, and the unoxidized carbon is surrounded by the melted binder in the heating stage (about 600 ℃). The fused 120 grit aluminum oxide harbor freight tools shall be clear and crisp when they are knocked, bright in color, and suitable for hardness and strength.

When the flame atmosphere is not strong and the flame is not fully burned, the carbon in the flame is adsorbed on the fine grit aluminum oxide surface of the abrasive tool, which also causes carburization, but this situation occurs on the surface of the outer diameter. When loading the kiln, the 220 grit aluminum oxide blast media sand cushion shall not be too fine, and the wheel stack shall be thin. In addition, the basin is too full, if paste semen or paraffin is used as a bonding wetting agent.


After firing, the color of 180 grit aluminum oxide is red, but the color of white corundum abrasive with iron oxide is inconsistent. The reason is that the oxidation atmosphere of abrasives is strong when they are fired, when the small grinding wheel is buried in sand, and the ventilation is not good. It is not necessary to process if the 80 grit aluminum oxide blasting media shape and size accuracy of the abrasive tools can meet the quality standard without machining.


The plane deformation of the 70 grit aluminum oxide blast media grinding wheel after burning is mainly caused by the fact that the grinding wheel is not leveled or the burning shrinkage is too large when the kiln is loaded. In order to prevent the deformation of the thin grinding wheel, a thicker grinding wheel is padded with 3-5 pieces of 100 grit aluminum oxide media sand. For the top layer, dim color, a thicker grinding wheel can also be pressed, which can also be burnt with buried sand.


Raw burning white fused alumina are not crisp, low hardness, poor strength. Through finishing, the geometric shape and dimensional accuracy of abrasive products can meet the quality requirements of finished products, making the surface of abrasive products consistent with the internal hardness, and improving the appearance quality of 1200 grit aluminum oxide products, which is conducive to the commercialization requirements and reducing the repair costs of users.


All 240 grit aluminum oxide that can meet the geometric shape and dimensional accuracy required by the quality standard only after white aluminum oxide being processed must be processed, the parallel and special-shaped grinding wheels with a diameter of ≥ 100mm processed in front of the kiln; the plane grinding wheel with a concave surface with a diameter of ≥ 125mm: the grinding ball grinding wheel: all kinds of grinding stones and special 46 grit aluminum oxide grinding tools required by the user.


There are obvious gray and black spots on the surface of white corundum after burning, even one piece. In order to prevent carburization of corundum abrasives. If necessary, the single-chip stacking method shall be adopted. Around the grinding wheel hole, there is black center or gray black, or the gap of the basin is too small, and the aluminum oxide blast media 60 grit surface expands. For large size grinding wheel, it can be kept at 1000 ℃ for several hours. 


In the heating stage of 400 ~ 1000 ℃, a strong oxidizing atmosphere should be kept in the kiln, and the 220 grit aluminum oxide heating rate should be slowed down properly. In the oxidation atmosphere, trivalent ti2o2 is converted into tetravalent TiO2 and combined with Al2O3 to form aluminum titanate-al2o3, such as the abrasives formed by water pouring; which is fine acicular crystal and causes certain turbidity in the transparent brown fused alumina manufacturer.
