Product Description

        Refractory Grade Brown Fused Alumina Abrasive Multi Size 325 Mesh


Brown fused alumina is produced through an electric arc furnace process, with characteristics of high purity, good crystallization, strong fluidity, low coefficient of linear expansion and corrosion resistance. Its thermal properties make it an excellent raw material for refractory applications,Brown Aluminum oxide has ability to withstand continuous exposure to the combination of heat, corrosion, abrasion and impact.Brown aluminum oxide section sand 0-1mm, 1-3mm, 3-5mm, 5-8mmIn is for refractory application, no explosion, no powdering and no cracking.

Brown Fused Alumina Applications :
 

Brown Aluminum oxide section sand 0-1mm, 1-3mm, 3-5mm, 5-8mm is applicable for

• Refractories, castables, refractory bricks

Brown fused alumina 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.

In the application process, it has the characteristics of no explosion, no powdering and no cracking.

 

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#
