Microcrystalline Fused Alumina obtains from varying the cooling rate of brown fused alumina. Microcrystalline Fused Alumina’s crystal size is very small and the abrasive grain is composed of fine crystalline blocks .Microcrystalline Fused Alumina has the characteristics of extra toughness and self-sharpening. 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 (One Fused Plant ,Three processing Factories, One Special Refractory material plant,One metallurgy material Plant,One Acid washing and Water washing plant, and Sales Department ).We can produce 80,000 tons annually.
