What is Graphite Crucible?

The graphite crucible is a kind of graphite mold, using as a carrier, which can put the raw materials and parts that we need to position or shape together in the graphite mold for high-temperature sintering, melting, or casting. The graphite crucible is made of artificial graphite blocks by mechanical processing.

The advantages of graphite crucible are as follows:

High-purity graphite crucible has excellent thermal stability, corrosion resistance, impact resistance, acid corrosion resistance, high thermal conductivity and quality stability, it has a certain resistance to rapid heat and cold. It is a kind of very excellent performance in molten gold crucibles, and is currently widely used in alloy tools The smelting of steel and the smelting of non-ferrous metals and their alloys. However, improper use of high-purity graphite crucibles will greatly affect its performance and service life.

Attentions of graphite crucible when using:

1: The high-purity graphite crucible must be slowly baked to 500 degrees Celsius before use. After use, it must be placed in a dry place to avoid water intrusion.
2: When using, it must be added according to the capacity of the high-purity graphite crucible, and the metals placed should not be squeezed too tightly to prevent the metal from thermally expanding and cracking the crucible.
3: When taking out the molten metal after melting, it is best to scoop it out with a spoon, use calipers as little as possible, and pay attention to the action to be light, to avoid impacting the crucible to excessive force and damage.
4: When using high-purity graphite crucible, avoid strong oxidizing flame directly spraying on the crucible wall, which will damage the crucible and shorten the service life.
