Graphite electrode Introduction:
Graphite electrode is made of high-quality low ash materials, such as petroleum coke, needle coke and coal pitch. After calcining, dosing, Mixing, forming, baking and pressure impregnation, it is graphitized in a high temperature of over 3000°C, and then machining.

Applications
- Graphite electrodes are used in electric arc furnace and ladle refining furnace for steel making;
- Graphite electrodes are used in electric smelting furnace for producing industrial silicon, yellow phosphorus, and corundum and so on.

Main properties:
1. Bulk Density: A measurement of weight per unit volume. A higher bulk density will general be reflected in improved mechanical properties of graphite electrode; the density is expressed in grams/cubic centimeter
2. Mechanical strength: It refers to the compressive, flexural and tensile strength. Higher strength in graphite electrodes/pins will generally result in lower breakage.
3. CTE: Lower CTE will give better resistance to thermal shock; also the CTE between the graphite electrode and nipples is important for the satisfactory performance of the electrode joint.
4. Specific resistivity: An electrical resistance of a unit length of graphite electrode. One of graphite’s useful property is that electrical resistance doesn’t increase strongly with the temperature
5.Ash: 0.5% max, and don’t contain elements harmful to steel making or other products
