CHARACTERISTIC :
1. Thermal stability: According to the quench acute thermal using conditions of graphite crucible, we
will specially design the production procedure, so as to ensure the reliability of product quality.
2. Corrosion resistance: Even and fine basic design will delay the erosion of crucible.
3. Impact resistance: Graphite crucible can bear high thermal impact, so any process can be carried out.
4. Acid resistance: The adding of special materials will greatly improve the quality of crucible, especially
its index of acid resistance., and will prolong the service life of graphite crucible.
5. High heat Conduction: High content of fixed carbon ensures the good heat conduction, shorten the time
of dissolution, and remarkably reduce the energy consumption.
6. Control of metal pollution: The component of material under strict control will ensure that graphite
crucible will not pollute the metals when dissolving.
7. Quality stability: The process technology of forming under high pressure and quality guarantee system will fully ensure the stability of quality.
8 .Using in high temperature process, thermal expansion coefficient is small ,it has resistance strain performance to hot and cold, Strong corrosion resistance to the acid, alkali solution;
Graphite crucible has good thermal conductivity and high temperature resistance, in use process at high
temperature, low coefficient of thermal expansion, the thermal, quench has certain anti strain properties.
The acid, alkali solution stronger corrosion resistance, excellent chemical stability.
Graphite crucible, because the performance is more excellent, so cast, in metallurgy, machinery, chemical
and other industrial sectors, is widely used for smelting alloy tool steel and non-ferrous metal and its
alloy smelting. And has a good technical and economic effect.
The technical level of domestic graphite crucible production has reached or even exceeded imported crucible,
crucible has the characteristics of high quality domestic:
1, the high density graphite crucible crucible has the best thermal conductivity, the heat conduction effect is
superior to that of other imported crucible;
2, graphite crucible appearance molding material special glaze layer and dense, greatly improving the products
corrosion resistance, prolong the service life;
3, graphite crucible in the full use of natural graphite, thermal conductivity is very good. Graphite crucible
heating can not be immediately placed in cold metal table, in order to avoid it due to the rapid cooling and
rupture.
A variety of small amount of alloy melting crucible is most suitable for use. In order to change the type of
alloy, graphite crucible can only exchange. The melting method as other reverberator and non induction
crucible furnace for melting, a lot of melting for single alloy, if the transform melting alloy type, if not changed
lining refractory materials, metal pollution will happen.
