High-purity graphite crucible has excellent thermal stability, corrosion resistance, impact resistance, acid corrosion resistance, high thermal conductivity and quality stability. 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.

 

Therefore, relevant experts have summarized the following points for the use of high-purity graphite crucibles.

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.

the high-purity graphite crucible has excellent performance, but in order to better use and prolong the service life of the high-purity graphite crucible, we must know the above instructions to avoid damaging it.
