Description:
Brown fused alumina is fused in electric-arc furnace by using carefully selected bauxite as a main material. AREF is a regular refractory grains can match various refractoris and metallurgic applications. AREF-T is a high performance brown fused alumina with lower impurity.
Applications:
Brown Fused Alumina is used for refractory material aspects, such as iron hook castable, anhydrous foam mud, corundum brick, pre-cast refractory, porous brick, ladle brick and Mag-Al-C brick.
