Graphite Electrode For Arc Furnace

Product description

Raw material and process Our graphite electrode choose low ash raw material of high grade petrol coke,

needle coke and coal pitch, processed with machining after calcimine adjuvant, mixing, forming, roasting ,

pressure impregnation and graphitization under 3000ºC high temperature.

Product sort Graphite electrode can be divided into ordinary power, high power and ultra high power electrode

by electrode quality index.


1.Graphite electrode of ordinary power Graphite electrode which allowable used current density is lower than

17A/cm2, are mainly used in ordinary power electric furnace for steel-making, silicon smelting and yellow

phosphorus smelting.


2.Graphite electrode with oxidation resistant coating Graphite electrode with oxidation resistant coating has

protective layer which can conduct electricity, heat resistant and anti-oxidation, reduce the electrode consume

when steel-making.


3.Graphite electrode of high power Graphite electrode which allowable used current density is lower than

18-25A/cm2, are mainly used in high power arc furnace for steel-making.


Characteristic of graphite electrode

1.Low resistivity,

2.Good conductivity,

3.Low ash,

4.Equality structure,

5.Good oxidative stability

6.High mechanical strength.


Application
Steelmaking in electric arc furnace, industrial silicon furnace, phosphorus furnace, the corundum furnace Nearly

30% graphite electrodes in our country are used for exportation, and domestic demand is mainly for steel making

in the electric arc furnace (35%), smelting of yellow phosphorus in submerged arc furnace(9%), abrasive (8%) and

industrial silicon (5%).Demands of the other industries is small.
