Graphite single ring crucible

Summary: Graphite crucible, also known as molten copper ladle, molten copper, etc., refers to a type of crucible made by firing graphite, clay, silica, and wax stone as raw materials. Graphite crucible is mainly used to melt non-ferrous metals such as copper, brass, gold, silver, zinc, and lead and their alloys.
Characteristics: Graphite crucibles have good thermal conductivity and high temperature resistance. During high-temperature use, the coefficient of thermal expansion is small, and they have certain strain resistance to rapid heating and cooling. It has strong corrosion resistance to acidic and alkaline solutions and excellent chemical stability.
Attention: 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.
