How to maintain when using graphite crucible
Oct 14, 2023
Graphite crucible has good thermal conductivity and high temperature resistance, because of this reason, in the process of high temperature, its coefficient of thermal expansion is small. So how do we maintain it in the process of use?
1. The graphite crucible must be stored in a dry place or on a wooden frame to prevent moisture.
2, when you hold it, you should be careful, it is strictly forbidden to shake.
3, hot baking before use in drying equipment or furnaces, the temperature rises to 500 ° C.
4, the graphite crucible should be placed under the surface of the furnace to reduce the wear of the crucible top.
5, according to the dissolution of the crucible, do not add too much to avoid the crucible too tight.
6, according to the shape of the crucible, the furnace and the crucible should be clamped in the middle to reduce stress damage to the crucible.
7, when cleaning the furnace slag and coke dissolved in the inner wall of the crucible, the crucible should be gently tapped to avoid damage to the crucible.
8, the crucible should be kept at an appropriate distance from the furnace wall, and the crucible should be placed in the middle of the furnace.
9, the use of an appropriate amount of accelerant, additives will reduce the service life of the crucible.
10, the crucible rotates once a week during use, extending the service life of the crucible.
