BROWN ALUMINUM OXIDE GRITS FOR GAS/OIL PIPELINES CUTTING
Brown Fused Aluminum Oxide is produced by fusion and reduction of calcined bauxite in an electric arc furnace, then made into different shapes and grit sizes.Brown fused aluminum oxide is commonly called as industrial teeth, it's a tough, hard material with high strength, excellent wear and corrosion resistance and good thermal conductivity.It is widely used as a raw material in refractories, grinding wheels, sandpaper, blasting media, lapping, polishing, cutting and grinding, etc.
Commodity: Brown Fused Alumina
Production Type: Tilting Furnace, Barmac Crushing, Air Blow Cleaning

What Is Difference Between Tilting Furnace Melted BFA & Fixing Furnace Melted BFA ?
Ball Milling & Barmac Process?
1. Tilting furnace process affects SiO2, SiO2 <1% by Tilting furnace, SiO2 <1.5% is by fixed furnace.
2. Barmac affects the density, the grain shape is rounder & the density is greater than ball milling
3. The Tilting furnace made BFA has high Al2O3 content
4. The corundum has good toughness & more suitable for abrasive products by dumping furnace process
The difference between F-grit & P-grit Abrasive grains:
F-grit is more suitable for bonded abrasive tools.
P-grit is more suitable for coated abrasive tools. It is with a closer tolerance size distribution, lower density, and better self-sharpening ability than non-P-grit abrasives, which means that they offer a more consistent surface finish.
Grit size: 16#, 20#, 24#, 30#, 36#, 46#, 54#, 60#, 80#, 100#, 120#, 150#, 180#, 220#
Micropowder: 240#, 280#, 320#, 360#, 400#, 500#, 600#, 800#, 1000#, 1200#, 1500#, 2000#
Refractory Grit size:1-0mm, 3-1mm, 5-3mm, 5-8mm, -200mesh, -240mesh, -320mesh.
