Lengthwise Graphitization Furnace Suitable for The Production Large Size Graphite Electrodes with Low Power Consumption

Product Description

Electrode Graphite with High Density Graphite Carbon Electrode Shp
Using coal pitch as binder, the graphite electrode which is mainly made of petroleum coke and needle coke is being made through the process of calcination, compounding, kneading, pressing, baking,impregnation, graphitization and machining. It is a conductor that release electrical energy to heat and melt the charge in the form of an electric arc in an electric arc furnace, and has the characteristics of low electrical resistivity, good electrical conductivity, low ash content, uniform structure, good oxidation resistance and high mechanical strength.
Materials: Needle coke,CPC,Coal Pitch;
Process: Petroleum coke calcined,Crush,Forming,Baking,Graphited,Machining;
Grades: RP/HP/SHP/UHP;
Application: Used in EAF/LF to make steel.
Features:
Low resistivity
Good conductivity
Low ash
Compact and uniform structure
Good oxidation resistance
Mechanical strength
Graphite electrodes are used mainly in ladle furnaces, electric-arc furnace steelmaking,
Yellow phosphorus furnace, Industrial silicon furnace or melting copper. They are presently
the only products available that have high levels of electrical conductivity and the capability
of sustaining the extremely high levels of heat generated in this demanding environment.
