China Factory Hot Sale Casting Graphite Mold for Aluminum Ingot

Professional solution provider including pyrolytic graphite, vapor chamber, silicone pad, die-cutting, specialties graphite, ceramic filtration membrane.

Specialty carbon graphite materials include medium grain graphite, fine grain graphite, and ultra-fine grain graphite.
Specialty carbon products (Carbon specialties) will realize the carbon's extensive potential. They are high-performance products that underline the development of key industries such as electronics, machinery, and metallurgy. They are also used in cutting-edge fields of science such as semiconductors aviation and the aerospace industry.

Features of specialties graphite:
* High temperature resistance, and the melting point is 3850±50°C, the boiling point is 4250.
* Low ash content, high purity, avoiding pollution to your products.
* Graphite material is easily to machine into any shapes you like.
* High mechanical strength
* Good sliding properties
* High thermal conductivity
* High thermal shock and chemical resistance
* Food safety
* Low wettability

* High density and high mechanical strength
* Proper electrical conductivity

Main properties of graphite specialties

7. Clean the crucible regularly and lightly.
8. The crucible should be put in the center of the furnace and leave some distance between the crucible and furnace.
9. Turn the crucible once in one week and this will help lengthen the service life.
10. The flame should not touch the crucible directly.
11.24 hours constant use will make crucibles have longer service life.
The smelt soup in the crucible should be cleared out when the furnace stop working, in order to avoid molten soup
solidificating and will be expanded when fire to reheat, and affect the service life of crucible or even burst.
12. We suggest that about 2 months for crucible melting aluminum alloy (every week for melting copper alloy), hanging out to check whether there is something wrong in the surface, and clean furnace hearth as well as turn the crucible, this operation ishelpful to prolong the service life of crucible.
