Refractory grade Brown fused alumina Size 3-5mm for castables
Brown aluminum oxide, also called Brown Fused Alumina, brown
corundum, artificial corundum, BFA, etc, is made by melting process
and reducing in electric furnace over 2200°C with three raw
materials of bauxite, anthracite and iron chip. Then made into
different grain size through cooling crystallization, sort, crush,
magnetic separation, screen size, blow cleaning etc..
The refractory grade section sand available sizes are 0-1mm, 1-3mm,
3-5mm, 5-8mm etc...
Commodity: Brown Fused Alumina
Production Type: Tilting Furnace, Barmac Crushing, Air Blow Cleaning
