Product Description:
Brown corundum is produced using bauxite and coke (anthracite) as the primary raw
materials, which are melted at high temperatures in an arc furnace.
Abrasive blasting is known for its short grinding time, high
efficiency, cost-effectiveness, and low price. The product exhibits
moderate hardness, high toughness, good self-sharpening ability,
low sand consumption, recyclability, and a fine grinding finish. It
boasts a stable chemical composition, wear resistance, and
resilience to acids and alkalis. The abrasive material features a
conchoidal structure with sharp edges and corners that can
continually form new edges, surpassing other abrasives in grinding
performance. Notably, its high hardness, specific gravity, chemical
stability, and unique self-sharpening quality make it an ideal
choice for abrasive blasting, enabling tasks such as rust removal,
decontamination, and achieving a matte finish.
Utilizing high-quality bauxite, anthracite, and iron filings, brown
corundum is produced through arc smelting at temperatures of 2000°C
or higher. After the melting process, the material is crushed,
plasticized by a self-grinding machine, magnetically separated to
eliminate iron content, sieved into different sizes, and results in
a dense, hard texture. The product takes the form of high spherical
pellets, suitable for applications in ceramic production,
high-resistance abrasives, resin-based materials, grinding,
polishing, sandblasting, precision casting, and high-grade
refractory manufacturing.
Brown corundum abrasive stands out for its high purity, excellent
crystallization, strong fluidity, low coefficient of linear
expansion, and resistance to corrosion. Extensive use by numerous
refractory production companies has confirmed its attributes of
explosion resistance, non-chalking, and crack prevention during
application. Significantly more cost-effective than traditional
brown corundum, it serves as the premier aggregate and filler for
fused alumina refractories.
Features:
Less Dust
Brown corundum is chosen for sandblasting due to its high density,
resulting in reduced dust during the sandblasting process. This not
only promotes operator health and safety but also enhances operator
visibility.
High Efficiency
When used under specific pressure, brown corundum can rapidly
impact the object's surface with numerous sharp edges, making it an
extremely efficient spray grinding method. The acceleration and
velocity of particles in the airflow depend on inertance and
particle size, with smaller particles being easier to accelerate
and generating higher impact force on the surface. As a result,
brown corundum offers a significantly faster cleaning rate, often
twice as fast as other traditional abrasives.
Low Depletion
The distinctive particle size of brown corundum ensures more
effective particle contact with the object's surface, leading to a
substantial reduction in abrasive loss when using brown corundum.
