Brown fused aluminum oxide, otherwise known as Brown Fused Alumina or BFA, is produced through an electric arc furnace process. Brown fused aluminum oxide is both a hard (Mohs hardness 9) and tough material with high strength, making it an excellent abrasive grain raw material for applications such as blast media, sandpaper, grinding wheels and abrasive discs, rolls, belts and pads. Its thermal properties make it an excellent raw material for refractory applications, as well. Because Brown Fused Aluminum Oxide has a high bulk density and high hardness making it the perfect media for removing rust, mill scale, and surface contamination. The consistent particle size allows for a uniform surface finish and coverage. Additionally, BFA has a low friability which allows it to be recirculated on average, up to seven times. These characteristics reduce abrasive consumption, clean up, and disposal costs, increasing profitability.

AZS Bricks, Alumina-Zirconia-Silica (AZS) refractories, belong to sintered ZrO2_Al2O3_SiO2 products family along with Zircon Mullite, Bonded AZS, Zirconia Corundum, and Rebonded Fused Mullite bricks. Sintered ZrO2-Al2O3_SiO2 products such as AZS have good resistance to alkali vapor and thermal shock. Mainly used in glass furnaces, they can withstand aggressive conditions in contact with molten glass. Typical applications are superstructures, skew blocks, wall bricks and upper-checker in regenerators, paving, sub-paving, and forehearth blocks in float glass furnaces. Our fused AZS blocks mainly inclue model AZS-33#, AZS-36#, and AZS-41#. the different models applicated in different parts of furnaces. AZS brick 33#, a normal refractory material, with the features of very good melting glass resisting, which seldom produces stone or other faults, and has little possibility to produce bubbles, widely used in glass Industrial furnace. AZS brick 36# has more free baddeleyite crystals in chain structure and less vitreous phase, which further improves the corrosion resistibility and reduces the potential defects in glass, so it is recommended to be used in sections where glass flow is faster and temperature is higher, such as melter sidewall, paving, doghouse, etc. AZS brick 41# has the most free baddeleyite crystals among the fused cast AZS families, which are evenly distgributed within the block. Its corrosion resistibility is the best and thus it is usually recommended to be used in the most demanding positions to balance the furnace life.
Chrome corundum brick is alumina - chrome oxide as the main raw material production of high-performance chrome corundum brick, has the characteristics of high refractoriness, great strength, good thermal shock stability, strong ability to resist erosion. Chromium corundum brick raw material is used by the ratio of alumina and chromium oxide according to certain proportion, go through high temperature melting synthesis of a solid solution. Using special refractory production technology made of refractory brick, can improve internal quality of the product, improve the high temperature performance of products. Feature 1.The refractory properties of chrome corundum brick In high purity corundum material add Cr2O3, no matter how much the amount, not only will not reduce the fire performance of materials can make refractory performance of material improved. 2.The strength of chrome corundum brick. The products in the process of burning, between particles and fine powder, between powder and powder are formed Al2O3 - Cr2O3 solid solution, calcium solid solution like bridge connect fine powder with particles together, make the strength of the material is greatly increased. 3.Thermal shock resistance Add Cr2O3 in corundum, when Cr2O3 content is 10% ~ 66%, material of thermal shock resistance decreased with increasing content of Cr2O3, namely the Cr2O3 content low chrome corundum brick, the thermal shock stability is better than Cr2O3 content high chrome corundum brick.
