Graphite Electrode Introduction
Graphite electrode is made by material calcination, kneading, molding, roasting, dipping, graphitization and machining, it is made of artificial graphite electrode. Graphite electrode is a kind of high temperature resistance graphite conductive material .
Graphite Electrode Properties
- Low electric resistance
- High density
- High Anti-oxidation capability
- Precise machiing accuracy
- Low sulphur and low ash will not give steel second time impurity

Electrode Graphite Application
- Used in Electric Arc Furnace Steelmaking Process
Graphite electrode is widely used in electric steelmaking. Electric steelmaking is utilized that graphite electrode introduce electricity into the furnace,
- Used in ore-smelting electric furnace
Ore-smelting electric furnace is mainly used to produce industrial silicon and yellow phosphorus, etc. Its characteristics is that the lower part of conductive electrode is buried in the furnace and form electric arc in material layer. The thermal energy produced by the resistance of furnace material itself to heat furnace material. In this paper, graphite electrode is required for ore thermal electric furnace with high current density. For example, 100 kg graphite electrode will be consumed when 1t silica is produced, 40kg graphite electrode will be consumed when 1t yellow phosphorus is produced.
- Used in Resistance Furnace
The graphitization furnace which is used to produce graphite products, kiln which is used to produce molten glass, electric furnace which is used to produce silica carbide, The material in the furnace is both a heating resistance and a heating object, Generally, graphite electrode for electric conduction embedded in the furnace head wall of resistance furnace , the graphite used in here is not continuingly consumption.
- Used in Making Shaped product
The workplane of graphite electrode is also used in to produce various crucible, moulds, boat and heating element and shaped graphite products. For example, in the quartz glass industry, every 1t fused pipe is produced,10 ton graphite electrode blank will be consumed; Every 1 ton quartz brick is produced, 100kg graphite blank will be consumed.
