Small Smelting High temperature Graphite Crucible for Induction
Furnace
1. Description
The crucible is an utensil or melting tank vessels that is made of
refractory material (such as clay, graphite, clay, quartz or
difficult molten metal iron, etc.).
Graphite crucible, which is divided into general type of graphite
crucible, special type of graphite crucible, high purity graphite
crucible.Graphite crucible, which is divided into general type of
graphite crucible, special type of graphite crucible, high purity
graphite crucible.
The main raw materials of Graphite crucible is natural crystalline
graphite. Therefore, it maintains the original natural graphite
various physical and chemical properties.
Graphite crucible has good thermal conductivity and high
temperature resistance;Uder the high temperature, the thermal
expansion coefficient is small, rapid heating, quench with certain
anti-strain properties. The strong corrosion resistance of acid,
alkaline solution has excellent chemical stability.
Graphite crucible, with their more excellent performance, in
metallurgy, casting,mechanical, chemical and other industrial
sectors, is widely used in smelting and alloy tool steel smelting
of non-ferrous metals and their alloys . Besides,it has achieved a
good technical and economic results.
2. Specifications from the graphite crucible
1. Long working lifetime: its working lifetime is increased 3-5
times over normal clay-crucible due to the compact body formed
under high pressure.
2. High thermal conductivity: high-density body and low apparent
porosity greatly improve its heat conductivity.
3. New-style materials: new heat conduction material ensures faster
heat conductivity and pollution-free product, reduces adherent
slag.
4. Resistance to corrosion:better anti-corrosion than normal
clay-crucible.
5. Resistance to oxidation: advanced process dramatically improves
its oxidation resistance, which ensures persistent heat
conductivity and long working lifetime.
6. High-strength: high-density body and logical structure make the
product better compression property.
7. Eco-friendly: energy-efficient and pollution-free, not only
ensure metal product purity, but also ensure sustainable
development on environment.
NOTICE: We also supply Copper-melting Clay Graphite Crucible and
Aluminum-melting Clay Graphite Crucible. Meanwhile, a matched
graphite stand is strongly recommended in order to expand the
lifetime and improve heat conduction of crucible.
