ISO9001 manufacturing and procesing of graphite electrodes
By:Win May 24, 2021
ISO 9001 is a global quality management system standard, which is the guarantee of the quality of graphite electrodes. Dancarbon graphite electrode products through the ISO9001 quality certification.
The main raw materials of graphite electrode are petrol coke and needle coke, pitch impregnation, through more than ten processes and graphitization of 2800~3000 ℃, can reach the technical data standard of using in EAF.
Graphite electrode is a very significant conductive material in electric arc furnace (EAF) steelmaking, with low resistivity as well as withstand high temperature of EAF.
The graphite electrode has a simple structure, which is composed of a rod and a nipple. The bodies are connected by a threaded joint. Usually, three or four electrodes connected by joints make a long column, then the column will be inserted in to EAF.

60% of graphite electrode production cost comes from raw materials, using petroleum coke, needle coke as aggregate, coal asphalt as binder.
Graphite electrodes manufacture process includes calcination, forming, baking, impregnation, graphitization and machining.
Graphite electrode can only be used in electric arc furnace if it meets ISO9001 quality standard, otherwise it is easy to break and fall off.
