Description
Supply Capacity
Brown Fused Aluminum Oxide powders are the perfect material specifically manufactured to be used for general abrasive applications in bonded abrasive tools, and lapping and polishing processes. While aluminum oxide has lower hardness and abrasive capacity than diamond, boron carbide, and silicon carbide, it is widely used for grinding ferrous materials, finishing tough and hard materials, filling up ceramic parts when the processing cost is important.Brown Aluminum oxide section sand 0-1mm, 1-3mm, 3-5mm, 5-8mm is applicable for
Refractories, castables, refractory bricks
Brown aluminum oxide is of high purity, good crystallization, strong fluidity, low coefficient of linear expansion, high temperature resistance and corrosion resistance.Widely used in the manufacture of advanced refractory materials:
- Castables,
- Refractory bricks,
- Ramming materials,
- Skateboards,
- Steel sliding nozzles,
- Ladle,
- Furnace linings,
- Smelting rare metals,
- Special alloys,
- Ceramics,
- Linings for ironmaking blast furnaces ( Wall and tube),
- Physicochemical utensils,
- Spark plugs,
- Heat-resistant anti-oxidation coating.
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.
