Graphite straight crucible

Summary: Graphite crucible is mainly made of graphite as the main raw material and processed with plastic refractory clay or carbon as the binder. It is mainly used for melting non-ferrous metals and their alloys such as copper, brass, gold, silver, zinc, and lead. The impurities (ash content) of artificial graphite crucibles are less than 1%, used for refining high-purity metals, as well as high-purity graphite that has undergone special purification treatment (ash content<20ppm).
Features: High volume density, high temperature resistance, fast heat transfer, acid and alkali corrosion resistance, high temperature strength, high oxidation resistance, stable quality, greatly improved service life, reduced fuel consumption and labor intensity.
Notes:
Graphite crucibles should be moisture-proof. Graphite crucibles are most susceptible to moisture, which can have a significant impact on their quality. If a crucible is exposed to moisture, it may experience cracking, bursting, chipping, and bottoming, resulting in loss of molten metal and even work-related accidents. Therefore, during the storage and use of graphite crucibles, it is necessary to pay attention to moisture prevention.
