Smelting of black fused alumina powder
The smelting method of black fused alumina is basically same with smelting of brown corundum. The production method of black fused alumina is choosing high-quality bauxite, iron oxide and other raw materials, add other trace elements, carefully smelting in dumping-type electric arc furnace , to ensure that the massive black fused alumina block are top grade, less impurities, ,stable quality. This laid solid foundation for producing period of black fused alumina sand , grain size black fused alumina sand and black fused alumina powder that are of moderate hardness, good toughness, good using performance and stability quality.
Prices of black fused alumina powder
In the abrasive products, brown fused alumina, white fused alumina, black fused alumina are same in using bauxite as main raw material, add iron scrap in high-temperature electric arc furnace smelting, and why the price of black fused alumina is lower than price of brown fused alumina and black fused alumina , The price of aluminum in the market than the price of iron per ton to be much higher, brown fused alumina sand content of more than 95%, while the black fused alumina a sand content of aluminum oxide To 85%, we can see the same level of fused alumina aluminum content is much higher than black fused alumina, and fused alumina products in the most valuable component is alumina, therefore, the price of black fused alumina is much lower than white fused alumina and brown corundum.
