YS/T 699-2018 Graphitized cathode carbon block for aluminium electrolysis
1 Scope
This standard specifies the requirements, test methods, inspection rules and marking, packaging, transportation, storage, quality certificates, and order (or contract) content of graphitized cathode carbon blocks for aluminium electrolysis.
This standard applies to graphitized cathode carbon blocks for construction of aluminum electrolysis cells that are not treated by impregnation and secondary rebaking during the production process (hereinafter referred to as “GCCB”).
