Graphite crucible sizes are various, ranging from 250g to 800kg. The most seen ones are 2kg/3kg/4kg/5kg/6kg/10kg graphite crucibles. It is mainly used for melting precious metals, gold, silver, copper, aluminum, and various kinds of moulds.

 

Graphite crucible for melting has high temperature resistance, strong thermal conductivity, special glaze layer and dense molding material, which greatly improves the corrosion resistance of the product and extends its service life. As an experienced graphite crucible supplier, our company provide mass purchasing and custom services as needed.

How To Temper A Graphite Crucible

  • Graphite crucible in the production of the main material is graphite, including clay, aggregate and other components. The graphite crucible temperature limit mainly depends on the graphite material, but also is affected by other materials.

 

  • The graphite crucible melting point is 3850±50℃ and the boiling point is 4250℃. Its strength increases with the temperature. At 2000℃, graphite strength is doubled. After ultra-high temperature arc burning, its weight loss is very small, thermal expansion coefficient is also very small.


FAQs of Graphite Crucible

  • Q:

    What is the manufacturing process of graphite crucible?

    The manufacturing process of graphite crucible can be divided into three kinds: hand molding, rotary molding and press molding. The quality of crucible has an important relationship with the forming method. The forming method determines the structure, density, porosity and mechanical strength of the crucible body.

  • Q:

    What are the specifications and dimensions of graphite crucible?

    Machining according to customer requirements and drawing size.

  • Q:

    Can graphite crucible be polished?

    Yes, according to customer's requirements, it will be more smooth and shiny after polishing.
