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. 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. We have passed ISO9001-2000 Quality Management System Certificate.
Black fused alumina is also known as low aluminum corundum. It is also a new type of product on the based of producing brown fused alumina by our plant. And it is a dark gray crystal body made α- Al2O3 and ferropicotite as main ore in the electric arc furnace by smelting the bauxite.Black fused alumina is characterized by low Al2O3 and a certain amount of Fe2O3 (10% more or less) content, so it has characteristics of moderate hardness, high toughness, high temperature resistance, and stable thermal stability. It is mainly suitable for free grinding, such as coarse grinding before electroplating products, mainly for polishing and sandblasting of stainless steel, fabricated metal products, optical glass, bamboo products, and it is also new abrasive for manufacturing resin grinding wheels, cut-off wheels and emery cloth. The black fused alumina of the company concentrated basic tablets, with the characteristics of strong cutting power, high toughness, high flexibility, good abrasion resistance and high working efficiency, which is the best product for grinding and polishing, sandblasting stainless steel products.
