High-purity graphite has the characteristics of high strength, high density, high purity, high chemical stability, compact and uniform structure, high temperature resistance, high electrical conductivity, good wear resistance, self-lubricating, and easy processing. It is widely used in metallurgy, chemical industry, and aerospace. , Electronics, machinery, nuclear energy and other industrial fields. Especially large-scale and high-quality high-purity graphite, as an alternative material, has a broad application space in high-tech and new technology fields, and has a wide range of application prospects.

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.
