rs brown fused alumina is characterized by high purity, good crystal, strong fluidity, low coefficient of linear expansion ,good corrosion-resistance and so on. after practical tests by dozens of refractory manufacturers, rs brown fused alumina can¡¯t burst¡¢pulverise and craze in the using course. in particular, its performance-cost ratio is much higher than traditional brown fused alumina, making rs brown fused alumina become the best aggregate and padding of brown fused alumina refractory materials. furthermore, our company , henan ruishi special refractory co., ltd. is established according to the modern management in 1993. as one of the main manufacturers and exporters for abrasive, refractory materials and metallurgy industry in china. we have six plants.we can produce 80,000 tons annually. our products include brown fused alumina95%, brown fused alumina98%,white fused alumina, black fused alumina, compact fused alumina, semi-friable fused alumina, micro crystalline fused alumina, calcium aluminate etc. brown fused alumina chemical composition: al2o3:95%min fe2o3:0.3%max sio2:1.5%max tio2:3.0%max magnetic material content(%) :0.05%max we have strict control about company & quality;our service is full-around and first-class. so we¡¯re you wise choice.don¡¯t hesitate to contact us. contact person: ms. liang xiaofei(sales manager) helen(at)rs-abrasive.com tel:+86 379 65285888-0 13015581246 fax:+86 379 66285889
