YUFENGREC® Brown Fused Alumina(BFA) are made of high quality alumina powder as raw material, by refining and crystallizing in electric arc furnace under high temperature .
Brown Fused Alumina has high compression strength, high toughness, excellent self -sharpening, low coefficient of thermal expansion, and excellent hydrophilia and cleanliness. It is a clean, high-strength material that resists oxidation and corrosion, maintains chemical stability, and withstands extraordinarily high temperatures.
The BFA is the main raw material for the production of unshaped and shaped refractory materials.
For the unshaped refracdtory material , it is wide used to high grade refractory castables, refractory gunning mix materials and other high quality monolithic refractory products;
For the dense refractory brick , it is mainly used in the high-quality corundum brick, corundum mullite,
It also can be used as materials for polishing, precision casting, spraying and coating, special ceramics and high-grade refractory materials,etc.
*High temperature resistance
Key Applications for Refractories purposes
* Cast steel slide gate, lining (wall and tube) of smelting rare metal, special alloys, ceramics, iron blast furnace, spark plug, heat resistant and oxidation resistant coating.
*Corundum insulation materials, such as corundum lightweight bricks, corundum bubble alumina bricks and fiber products, it is widely used in furnace walls and furnace roofs of various high-temperature furnaces, which are resistant to high temperature and heat preservation.
Key Applications for Abrasives purpose
* Grinding metal, such as a variety of common steel, malleable iron and hard bronze, etc.
* Grinding media, sandblasting media, surface cleaning, sandblasting, polishing, grinding, etching, wet and dry blasting, mineral skin abrasion materials.
*Metal finishing & surface preparation, ceramics, coatings, bonded & coated abrasives.
