A crucible is a container used to hold metal for melting in a furnace and it is needed to withstand the extreme temperatures encountered in melting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength even when white hot.Graphite crucible can withstand the high temperature, and has good resistance to chemical erosions and thermal shock. Especially graphite crucible is ideal for the melting of aluminum, copper and etc.

 

We can offer graphite crucibles in different sizes and types. Whenever you need it, just feel free to contact us, and we will reply you in the shortest time.

Applications:

   1. Melting gold / silver / lead / zinc / brass / copper / aluminium,etc metals.

   2. Like non-ferrous metals and  aluminium alloy melting.

   3. The sic graphite crucible is widely used in metallurgical industry.

Materials:

Molded Pressing Graphite 

The moulded graphite is made from the raw materials of high quality pitch, petroleum coke and other aggregate and binding materials, through the processing of grinding, kneading, second grinding, moulded forming, baking, impregnation with pressure, second baking, graphitization in high temperature, refinement etc.

Isostatic Pressing Graphite 

The isotropic graphite is made from the raw materials of high quality pitch, petroleum coke and other aggregate and binding materials, through the processing of grinding, kneading, second grinding, isotropic forming, baking, impregnation with pressure, second baking, graphitization in high temperature, refinement etc. Isotropic graphite is widely used in the fields of semi-conductors, solar & photovoltaic, EDM processing, aerospace & defense, metal continuous casting and other industries. The granule D50 is between 10um to 20um.
