Brown Fused Alumina for refractory
Brown Fused Alumina is fused in the electric-arc furnace under the high temperature of above 2250 C with high quality abrasive bauxite as raw material and matched by the carbon material and scrap iron. The degree of refractory is more than 1850 C.
In order to meet the demands of the refractory industry.
We independently develop and produce Brown Fused Alumina which is adopted by modern unique technology of smelting and processing under the universities and research institutes' support.
Brown Fused Alumina is characterized by high purity, good crystal, strong fluidity, low coefficient of linear expansion, good corrosion-resistance and so on. After practical tests by dozens of refractory manufacturers, Brown Fused Alumina can't burstpulverise 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.
