International standards for graphite electrodes
By:Win Nov 18, 2020
IEC 60239-2005 is an international standard for graphite electrodes. It is a standard editing group that collects standards for UCAR of the United States, SGL of Germany, Tokai carbon of Japan, DanCarbon of China and HEG of India.
Graphite electrode is an important conductive material in steelmaking. The graphite electrode is composed of body and nipple
, which is connected by 3 graphite electrodes of the joint.
Standards for graphite electrode in china
In addition to IEC 60239-2005 standards, China's graphite electrode production should also comply with relevant standards of China's graphite electrode industry.
YB/T 4088 Graphite electrode
YB/T 4089 High power graphite electrode
YB/T 4090 Ultra high power graphite electrode
The standard content of graphite electrode is mainly some performance indexes. Volume density DB, resistivity, flexural strength, elastic modulus E, coefficient of thermal expansion and ash A% of graphite electrode. Graphite electrode manufacturers must meet these standards before they can be used in steel mills.
