Brown fused alumina is made of bauxite, anthracite and iron filings, and is smelted at high temperature in an electric arc furnace. During the smelting process, the carbon in the anthracite reduces impurities such as silicon oxide, iron oxide, and titanium oxide in the bauxite to metals, and these metals are combined to form a ferroalloy, which settles to the bottom of the furnace due to its larger specific gravity than the corundum solution. The corundum solution separates. Only a small amount of impurities are included in the corundum frit.

White corundum fine powder is very suitable for wet sandblasting and polishing operations, does not affect the color of the workpiece, can be used for prohibited processing of iron powder residue, fast processing speed, good quality, low iron oxide content, suitable for PR sandblasting operations. Suppresses iron powder residue. Can be used repeatedly as sandblasting abrasive. The number of times it is used is related to the blasting material, the particle size of the micropowder, and the hardness and level of the micropowder.

As an ideal raw material for non-metallic materials,Green silicon carbide powder It is undoubtedly a widely used raw material, what are its use steps and methods?

Brown corundum, like white corundum, is also made of alumina powder as the main raw material, suitable for chromium oxide, etc., and smelted at high temperature. However, because of their smelting methods and properties are slightly different, resulting in certain differences in their use process, the following Haixu Abrasives Xiaobian will introduce to you:White corundum Sandblasting is the difference from brown corundum sandblasting.

Green silicon carbide Which one is good? When it comes to green silicon carbide, people who make abrasives must be familiar with it, and green silicon carbide has a very important role in the abrasive industry. So which green silicon carbide is better?Green silicon carbideWhat are the production processes and uses?

White corundum It is a high-grade refractory raw material with -Al2O3 as the main crystal phase and white color. It has the characteristics of high bulk density, low porosity, good volume stability and good thermal shock resistance.

Brown corundum abrasive  is widely used in components of reaction vessels, pipelines and chemical pumps due to its high hardness, high strength and good wear resistance; it is used as mechanical parts and various grinding tools in the machinery industry. Drawing dies, pencil core dies, extrusion nozzles, etc.; making tools, bulletproof materials, mold abrasives, body joints and sealing mold rings.
