Brown Fused Alumina for Refractory

Brown Fused Alumina also is known as BFA. It belongs to the group of electro-corundum. It is produced by smelting mixtures of calcined bauxite, iron and coke(anthracite) in an electric arc furnace at temperatures more than 2000°C. It’s a hard, tough, dense, fire-proof, sharp-edged, wear-resistant, and corrosion-resistant material. Brown Fused Alumina for Refractory is a mineral with good particle distribution for shaped and unshaped refractory products in fire-proof, precision casting, foundry and coating industries. Our Brown Fused Alumina Refractory Grades is a high-grade refractory material with high purity, high cleanness, coarse grain, low magnetic contents, high density, high bulk density, chemical stability, and low porosity rate, excellent crystal structure, corrosion and acid-resistant. It is widely used in the production of refractory bricks, steel making industry, ceramic, glass, cement industry etc.

Brown Fused Alumina for Refractory(FAQ)

What does the term “flow properties” mean?

The flow behaviour of powders depends on many factors. The following applies in general: Coarser, dry grain types flow easily, but the fine the grains get, the stronger is the impact of morphology and various adhesive forces on the flow behaviour: Van der Waals forces Liquid bridges Electrostatic interaction The

What is the specification?

A typical grinding wheel specification consists of the grit type, the grit size, the hardness, the structure and the bond.  A typical grinding wheel specification would be A60-I10-VS.  ‘A’ is the grit type (aluminum oxide), ’60’ is the grit size, ‘I’ is the relative hardness, ’10’ is the structure, and

What is your sample policy?

We can supply the sample if we have ready parts in stock, but the customers have to pay the sample cost and the courier cost.
