What is Brown Fused Alumina
Brown fused alumina, also known as brown aluminum oxide, is a type of synthetic abrasive material that is made by fusing bauxite with other materials in an electric arc furnace. It is known for its high hardness and durability, making it a popular choice for a wide range of industrial applications.Brown fused alumina was first produced in the 1890s, and its use as an abrasive material quickly became popular in various industries. Over time, improvements were made to the production process and new applications for the material were discovered.
Benefits of Brown Fused Alumina
No ferrous contamination
Brown Fused Aluminum Oxide abrasive is more than 95% pure aluminum oxide. Blasting with Brown Fused Aluminum Oxide will not promote ferric contamination or rust on your surface. This makes Brown Fused Aluminum Oxide the preferred abrasive choice in applications where ferrous contamination is a concern.
Increased production
Brown Fused Aluminum Oxide's higher bulk density and high hardness results in more energy being transferred to the work surface than mineral or slag abrasives, easily removing surface contamination, rust, and mill scale. Brown Fused Aluminum Oxide's uniform particle size provides consistent coverage and surface finish, increasing production rates.
Recyclability
The low friability of Brown Fused Aluminum Oxide allows it to be recycled up to seven times or more. Unlike mineral or slag abrasives, Brown Fused Aluminum Oxide will not completely shatter when it hits a surface, keeping its relative size. Recycling Brown Fused Aluminum Oxide increases profitability by reducing abrasive consumption, shipping, cleanup, and disposal costs. Abrasive blast cabinets provide the best recyclability rate.
Application of Brown Fused Alumina
Abrasive Industry
As an abrasive, Brown Fused Alumina offers certain benefits and traits. First off, it is a stiff abrasive with a very high degree of hardness, making it more efficient in removing materials from the workpiece's surface during the grinding and polishing process. This results in higher processing effectiveness and better processing quality. Additionally, Brown Fused Alumina is difficult to wear and has strong abrasion resistance, allowing it to retain a long service life during usage. Brown Fused Alumina is particularly significant in the field of high-temperature processing due to its exceptional thermal stability and ability to retain performance at high temperatures.
Refractory Raw Material Industry
When creating refractory bricks and coatings, brown fused alumina is a crucial component. Due to Brown Fused Alumina's strong refractoriness and abrasion resistance, which make up one of the key components of refractory bricks, refractory bricks can survive high temperatures and chemical assaults, making them a common component of industrial furnaces and high-temperature kilns. Furthermore, Brown Fused Alumina particles in refractory coatings improve adhesion and abrasion resistance, prolonging the useful life of refractory coatings and shielding the surface of refractory bricks from extreme heat and chemical degradation.
How to Choose Brown Fused Alumina
Material Being Worked on
The type of material being worked on is another crucial factor to consider when selecting Fused Alumina. For example, if you are working on stainless steel or non-ferrous metals, Black Fused Alumina is the right choice. If you are working on metals, wood, or plastics, Brown Fused Alumina is ideal.
Desired Finish
The desired finish is another factor to consider when selecting Fused Alumina. For example, if you need a smooth and shiny finish, White Fused Alumina is the right choice. If you need a rough finish for surface preparation, Black Fused Alumina is the best choice.
Particle Size
The particle size determines the abrasive's cutting power and the surface finish. Smaller particles provide a smoother finish, while larger particles provide a rougher finish.
Cost
Different grades and types of Fused Alumina have different prices. It is essential to consider the cost-effectiveness of the material for your application.
The quality and consistency of the material
When choosing the right Fused Alumina, it is also essential to consider the quality and consistency of the material. The quality of the Fused Alumina can affect the final product's quality and consistency. It is crucial to choose a reputable supplier that can provide high-quality and consistent Fused Alumina.
Packaging and storage
Another factor to consider is the packaging and storage of the Fused Alumina. The packaging should be durable and able to protect the material from moisture and contaminants. The storage conditions should be dry and cool, away from direct sunlight and heat.
Safety guidelines
It is also important to follow the recommended safety guidelines when handling Fused Alumina. Fused Alumina is a sharp and abrasive material that can cause injury if not handled correctly. Always wear protective gear such as gloves, eye protection, and a dust mask when working with Fused Alumina.
Process of Brown Fused Alumina
Calcined Bauxite, Anthracite and Iron Fillings are the main raw materials for producing of Brown Fused Alumina. BAIYUN GROUP choose the best quality calcined bauxite which contains about 88% aluminium oxide, which is the main source of Al2O3 in BFA. These raw materials are mixed together at certain proportion and fused/smelted in electric arc furnace in about 2200℃. Common furnaces are Fixed Furnace or Tilting Furnace (Dumping Furnace).
The fused BFAare cooled down and crushed into big lumps which look brown. This is material of high aluminium oxide content. BFA lumps are then crushed into smaller sizes for further production.
Brown Fused Alumina lumps grits are then put into crushers for further crushing into smaller sizes and screened into grits of different sieving distribution. This is coarse finer grades of good sieving distribution suitable for abrasives and refractory purposes. There are different quality standard such as GB, FEPA, JIS, ANSI standards. After screening, content of Aluminium Oxide (Al2O3) is about 95%, with little content of Iron Oxide (Fe2O3), Titanium Oxide (TiO2) and Silicon Oxide (SiO2) and little magnetic contents. Magnetic contents are then removed relevant equipment, which process is important as for refractory and abrasives applications magnetic contents will harm the finished products. For Al2O3, the finer(smaller) the grit is, the lower the content is.
Brown Fused Alumina grits are then washed by water or acid to remove dust, magnetic contents and impurities. These unnecessary contents are easy to cause scratch, corrosion, cracks and dark spots on abrasives and refractory products. Washing process also helps get harder and purer materials which have better performance and better for recycling.
After production, Brown Fused Alumina are packed and shipped to customers. Most common packing are Big Bags of 1 metric ton, 1.2 or 1.3 metric tons. Or packed into 25kg woven plastic bags or 25kg paper bags, and 40 bags on a pallet.
How To Distinguish The Quality Of Brown Aluminum Oxide Micropowder
Look at the color first. The color of brown aluminum oxide is usually brown and translucent. If the color of brown aluminum oxide is lighter, it has high aluminum content and appears shiny brown. Under the sunlight, brown corundum has high transparency. Relatively speaking, if the color of brown corundum is darker with a little cyan, then this kind of brown corundum will have greater hardness, higher wear resistance, and higher iron content.
The smaller the particles of brown aluminum oxide, the lighter the color, such as brown aluminum oxide powder, even has a light gray color, on the contrary, the larger the particles of brown corundum, the darker the color, but no matter the particle size, the material of brown corundum Are the same. Therefore, the depth of the color of brown aluminum oxide is related to the particle size.Brown fused alumina is divided into three quality grades, the best of which is grade 1 brown fused alumina, followed by grade 2 and grade 3. The quality of brown fused alumina is mainly based on the content of Al2O3.
