Products Description

This is a set of round gold melting graphite crucibles, which are often used as tools for high-temperature precious metal smelting, mainly due to its unique material properties, structural design and process adaptability.
The gold melting graphite crucible is made of high-purity graphite material, with high melting point, high thermal conductivity and chemical inertness. It can withstand the high temperature environment required for gold melting and effectively avoid metal liquid contamination, thereby ensuring the purity of molten gold.
This set of graphite crucibles adopts a circular structure design, which can effectively reduce local overheating or thermal stress concentration through 360° thermal radiation, and combined with the high thermal shock resistance of high-purity graphite, it greatly improves its service life. At the same time, the wall thickness and caliber ratio are optimized to ensure the thermal efficiency of the gold melting process.
This graphite crucible is very popular in small and medium-sized gold smelting, such as jewelry processing, precious metal recovery and laboratory refining. It is light and easy to hold. When combined with induction heating equipment, it can quickly reach the target temperature and achieve precise temperature control, which can meet the metal fluidity requirements of jewelry casting.
There are many types of crucibles on the market. Compared with ceramic crucibles, graphite crucibles have a lower thermal expansion coefficient and are not easy to crack under repeated hot and cold cycles. They are economical and efficient and are deeply loved in the casting field.
During the use of graphite crucibles, it is important to avoid contact with strong oxidants. After smelting, sandblasting is required to clean the residue to maintain the smoothness of the inner wall.
