Aluminium Oxide Abrasive Grit Manufacturers Malaysia

Chrome-fused alumina bricks in use are called fused-corundum bricks. Under normal circumstances, aluminum oxide abrasive media content above 90% is called corundum brick. Chrome corundum brick generally refers to sintered chromium corundum brick. Adding a proper amount of chromium oxide powder and 180 grit aluminum oxide blasting media clinker powder with -al2o3 as raw material, after firing, it is fired at high temperature.

The content of chromium oxide in sintered black aluminum oxide media bricks is generally lower than that in fused cast chromium alumina bricks.Also, it is possible to mix the α-alumina powder and chromium oxide powder by mud pouring method, and add a part of chrome corundum clinker. This is the method of brick grouting. Fused chrome zirconium corundum brick is also called AZCS brick, which adopts non-shrink casting process.


The skin and interior of the brick are dark green. The white fused alumina brick contains 4.5% shrinkage holes and no connection air holes. Non-ferrous glass kiln can use AZCS brick containing Cr2O3 to build the pool wall, which improves the corrosion resistance of the pool wall. The glass phasor is similar to ordinary fused AZS bricks. The alumina abrasive chemical composition of the glass phase was determined through micro-analysis.


A large amount of Cr2O3 was dissolved in the glass, and the corundum abrasive forming the glass structure was identified as Cr2 +. That is, cr3 + is reduced to Cr2 + in the melt. At present, chrome corundum bricks have been widely used, mainly used for carbon black furnaces, steel rolling furnace slides, and steel platforms. The number of glass phases is similar to that of ordinary fused AZS bricks, 220 grit aluminum oxide which is about 20%.


Sintered white aluminum oxide bricks are widely used in glass kiln linings, cover glass bricks with flowing liquid holes, glass fiber kiln bodies and upwinds, stained glass kiln in severely corroded parts, insulated glass fiber kiln walls, hot metal pretreatment equipment at the bottom and in front of furnace. The minor mineral composition is refractory bricks with a small amount of composite spinel (or no composite spinel) and white alumina powder content of 1% to 30%. 


Electro-fused fused alumina brick and sintered aluminum oxide 220 grit abrasive brick both belong to chrome alumina products, but the two products have different colors due to different production processes and different raw material ratios. With the support of the coal-water slurry pressurized gasifier, the metallurgical molten pool, rotary kiln, and zinc melting furnace of the ceramic glaze kiln discharge opening. The main crystal phase of 60 grit aluminum oxide is (al2-xcrx) O3. 


In general, chrome-corundum bricks refer to sintered chrome-corundum bricks. The white corundum content of sintered chrome corundum brick is generally lower than that of fused cast chrome corundum brick. There are two types of chrome alumina products: (fused fused alumina bricks) fused cast alumina bricks and sintered 100 grit aluminum oxide blast media bricks. This is due to the fact that the melt is in a relatively reducing atmosphere. 


It can also be prepared by slurry pouring method. Α-Al2O3 powder and aluminum oxide 40 grit powder are evenly mixed, and a thickening slurry is made by adding a dissolving agent and an organic binder. At the same time, a part of chromium corundum clinker is added to make bricks by the grouting method. After firing, the 150 grit aluminum oxide product has the characteristics of wear resistance, thermal shock resistance, acid and alkali resistance, etc.
