Brown fused alumina is fused in the electric furnace with the high quality abrasive grade bauxite , coal and scrap iron as the raw material.
Brown Fused Alumina for refractory is characterized by high purity, good crystal, strong fluidity,
low coefficient of linear expansion ,good corrosion-resistance and so on.
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 Brown Fused Alumina become the best aggregate
and padding of brown fused alumina refractory materials.
