Denetlenen Tedarikçi Graphite crucible
Graphite crucible is made from our high quality graphite block, and widely used in all kinds of furnace for melting such as jewelry, gold, silver, copper, brass, iron, aluminum, zinc, lead and so on.
Based on working environment, we could supply the molded graphite, isostatic graphite, medium grain graphite, and some imported graphite materials for making the crucibles.

There are various selections of the materials. Based on the working environment, our engineers will offer the suitable graphite material.
Do you know operating instruction of the graphite crucible?
1. The crucibles should be put on the pallets instead of the ground and stored in a dry place with good ventilation.
2. The crucibles should be carried on the special transport machine, so. Please don't roll the crucible directly.
3. Use the proper base to support the crucibles. Attention! The base should be with a bigger diameter than the crucibles' bottom and with the same material as the crucibles'.
4. Don't pack the crucibles too tightly
5. Allow the crucibles have enough expansion and extraction space.
6. Avoid high pressure on the crucibles' top
7. The furnace cover should not be pressed on the crucibles' top.
8. Make sure the furnace lining works well and repair it if there is damage,
9. Make sure the crucible and furnaces are concentric.
10. Don't throw or drop metal ingot into the crucible is forbidden; use pincers to put the metal into crucible carefully
11. Put the metal ingot into crucible vertically not horizontally; be sure there is some space between ingot and inside wall of crucible.
12. Check the burner position in order to ensure the flame is under the joint of crucible and base plate, flame cannot touch the crucible directly.
13. Be sure the tooling and fixture is fastness and prop the bottom always.
14. Don't add up refining agent into the crucible before the aluminum ingot melting is forbidden
15.Clear up slag regularly using proper tool to protect inside wall of the crucible.
