Notes of operating graphite crucibles
1. The crucible should be stocked in the dry situation
2. Carry the crucible lightly
3. Warm the crucible in the drying machine or near the furnace. The warming temperature should be up to 500℃.
4. The crucible should be put under the furnace month flat.
5. When put the metal into the crucible, you should take the crucible capacity as your reference. If the crucible is too full, it will be damaged by expansion.
6. The clamps shape need as that of crucible. Avoid the concentrate stressed destroy of the crucible.
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.
