White corundum is a white abrasive made
from industrial alumina powder (Al2O3) with a content of over 98% and a small
amount of iron oxide and silicon oxide. It is a white abrasive which is melted
at high temperature. Its hardness is slightly higher than that of brown
corundum and its toughness is slightly lower. It is made by smelting and
cooling above 2000 degrees in arc, grinding and shaping, removing iron by
magnetic separation, and sieving into many kinds of granularity. It is compact
in texture, high in hardness and sharp in shape. It is suitable for making
ceramics, resin-bonded abrasives, grinding, polishing, sandblasting, precision
casting (corundum for precision casting), etc. Manufacture of high-grade
refractories, code name "WA" in the international common standards,
national standards consistent, most for export, but also a certain amount of
supply to domestic users.
The product size is produced according to
international standards and national standards, and can be processed according
to user requirements. The general size is F4~F220 and w63-w2.5 has different
chemical composition depending on the particle size. The prominent feature is
that the crystal size is small and impact-resistant, if the grinding machine is
used to break, the particles are mostly spherical particles, the surface is
clean and easy to bind.
The abrasive tools made of white corundum
are suitable for grinding high carbon steel, plateau steel, high speed steel
and quenched steel with harder and stronger tensile strength. It is suitable
for solid structure and coated abrasive tools, wet or dry jet sand, ultra-fine
grinding and polishing suitable for crystal and electronic industries and
making high-grade refractories.
It can also be used as grinding and
polishing materials, precision casting sand, spraying materials, chemical
catalyst carrier, special ceramics, advanced refractories, etc. It is
characterized by strong cutting force, good chemical stability and good
1. It is suitable for quick removal of
oxide scales on the surface of bearing rings after heat treatment.
2. It is suitable for the deburring and
polishing of stamping and combined iron retainers. For copper holders, the
finishing process completely replaces the original pickling process.
Chamfering, deburring and polishing not only improve the product quality, but
also improve the working environment, in line with the national environmental
3. It is suitable for surface polishing of
bearing cylindrical roller, tapered roller, spherical roller and needle roller,
greatly improving the surface roughness and brightness.
