3 terms and definitions
The following terms and definitions apply to this standard.
3.1
Graphite crucible is a natural flake graphite as the main raw material, with refractory spices and binders (clay or resin, asphalt, etc.), through plastic
Molding or isostatic pressing, and by high temperature sintering, for melting and refining high-temperature non-ferrous metal heat-resistant containers.
3.2
Artificial graphite electrode billet, machined from the artificial graphite crucible.
3.3
With a purity of 99.9% or more high-purity graphite blanks, the mechanical processing of high purity graphite crucible.
3.4
Carbon crucible
Mainly to the carbon raw materials, processed by the carbon crucible.
3.5
Plastic molding
The use of mold or tool movement caused by the pressure, shear, extrusion and other external forces on the plastic with the blank processing, forcing the blank
In the external force under the action of plastic deformation and the formation of blank forming method.
