Clay graphite crucible otational Molding type
Large Foundry Clay Graphite Crucibles Supplier
Product Description
physical and chemical index:
Refractory temperature: 1600℃
Carbon content: 40%
Bulk density: 1.7g/cm3
Apparent porosity : 32%
silicon carbide content: 24%
Long working lifetime: clay crucible working lifetime is increased 3-5 times over normal clay-crucible due to the compact body formed under high pressure.
High thermal conductivity: clay crucible high-density body with low apparent porosity greatly improve its heat conductivity.
New-style materials: clay crucible new heat conduction materials ensure faster heat transference, reduces adherent slag and pollution.
Resistance to corrosion: clay crucible better anti-corrosion than normal clay crucible.
Resistance to oxidation: clay crucible advanced process dramatically improves its oxidation resistance, which ensure persistent heat conductivity and long working lifetime.

Above specifications depends on the actual inventory
Product instructions:
1.Crucible need to stored in ventilated and dry environment, avoid moisture to affected application.
2.Crucible should be handling gently, do not roll, in case not to damage the protective layer on the surface of crucible
3.Before use,need baking crucible,the baking temperature from low to high slowly heat up, and constantly flipping crucible and let its uniform heat, eliminate moisture , preheating temperature gradually rises to more than 500℃ (if preheating undeserved, will lead to blowout, spalling,this not belong to quality problems, won’t be refund)
4.Crucible furnace need mating with crucible, the gap of around need to meet the requirements, furnace cover can’t pressure on the crucible.
5.Need to avoid flame spray on the side of crucible, should be sprayed to the crucible bottom.
6.When feeding raw material, should be slowly, big size material don’t install too much and tight,avoid to crack crucible.
7.Crucible tongs need suitable with crucible, to avoid damage crucible.
8.Crucible better be continuous used, in order better to play its high performance.
9.Need to periodic rotation when using crucible, for heated evenly, prolonged use
10.When remove the slag and stick cokes of crucible, should tap gently, to avoid damage to the crucible.
