Anti-Oxidation Coated Degassing Graphite Tubes for Aluminum Purification

Product Details

A: Company profile
L.T Group has a comprehensive product and technology portfolio that
focuses on four fields of graphite - ultrafine particle graphite mould,
graphite electrode, graphite crucible, as well as other products mainly
made of graphite.
Graphite materials exhibit unique properties such as good electrical and
thermal conductivity, heat and corrosion resistance, low friction, and reduced
weight while at the same time maintaining high strength. Due to the shortage
of energy and raw materials, our high performance products made from graphite
are in increasingly high demand in industries. They also play a progressively
important role in everyday life, thereby substituting traditional materials.


B: Graphite rotor introduction
Graphite rotor is mainly used in liquid aluminum, aluminum alloy purification
process, to improve the purity of aluminum or aluminum alloy. It is the most
advanced treatment method in the world that mix the purification gas and solvent,
use the rotating jet of the graphite rotor to purify the aluminum during the
purification process,
Under high temperature aerobic conditions, in the production process of
on - line degassing machine for fine aluminum casting, graphite rotor has
defects of easy oxidation & break, no friction. Our team choose high quality
reasonable ratios of graphite materials, coated with high temperature
antioxidants which was R&D independently while no pollution to the
Aluminum liquid. Our unique anti-oxidant graphite rotor performs outstanding
oxidation resistance, corrosion resistance, high hardness, high compressive
strength makes continuous use for 90-120 days available, thus effectively
reduce producing cost for customers.


C: Working principle:
A twirling graphite rotor shatters nitrogen (or argon), which is blown into
melting aluminum, into profuse bubbles that disperse in the liquid metal.
Regarding gas pressure difference and surface adsorption principle, bubbles
in the melt absorb hydrogen and oxidation slag inclusion which are taken out
to surface of the melt with the rise of the bubbles, so that the melt can be purified.


D: Working conditions:
Put the impeller end and part of the shaft of a graphite rotor into
690°C-780°C Aluminum liquid, rotation speed 500 RPM, 1-2 hours at a time,
work for 4-6 times per day. graphite rotor can also work continuously according
to the working condition of the equipment.

E:Product features:
1. Our graphite rotor is made of high-quality graphite material.
2. After special anti-oxidant treatment, the service life could reach 5 -10 times
compared to ordinary market graphite rotor.
3. Our graphite rotor widely used in high purity aluminum industry and
aluminum alloy casting industry.
