Description

Technical Field

[0002] Graphite crucible, also known as melting copper bag, melting copper, etc., refers to a type of crucible made of graphite, clay, silica and wax stone as raw materials. Graphite crucible is mainly used to smelt non-ferrous metals and their alloys such as copper, brass, gold, silver, zinc and lead. Graphite crucible is made of natural flake graphite as the main raw material and plastic refractory clay or carbon as a binder. It has the characteristics of high temperature resistance, strong thermal conductivity, good corrosion resistance, and long service life. When processing the graphite crucible, it needs to be polished.

When this structure is used in actual use, due to the fixed size of the graphite crucible grinding sheet, only one position of the graphite crucible can be polished, and the position of the graphite crucible needs to be frequently changed, which undoubtedly increases the labor intensity.
