Product Description

F20 Brown Fused Aluminum Oxide For Structural And Plate Steel Maintenance

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..

suitable for the production of ceramic, high-resistance abrasive resin and grinding, polishing, sandblasting, precision casting, etc., can also be used to manufacture high-grade refractories.

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.
