What Are Graphite Electrode Granules Made Of?
Graphitized petroleum coke is the primary raw material used in the production of graphite electrode granules. This highly graphitized form of petroleum coke provides the core structure and essential properties, such as high electrical and thermal conductivity, chemical inertness, and thermal stability. To hold the graphitized petroleum coke particles together, various binder materials are added to the formulation. Common binders used include pitch (coal-tar pitch or petroleum pitch), resins, and other carbonaceous materials that can form a strong, cohesive matrix. Small amounts of other additives may be included to enhance specific properties or improve the manufacturing process. These additives can include materials like filler materials, lubricants, or processing aids. The exact composition of graphite electrode granules can vary depending on the specific application and the desired properties of the final product. However, the high-purity graphitized petroleum coke is always the primary and essential component that provides the core characteristics of the graphite electrode granules.
Graphite Electrode Granules Properties You Need to Know
Specific Resistance / Electrical Resistivity
It is the resistance to the passage of electric current. A low resistance value allows a higher current intensity without the electrodes overheating.
Apparent Density
It is the weight per unit volume. A higher bulk density usually reflects better mechanical properties.
Resistance to Tension
It is the force that is required to produce a break by tension. A high value reduces the number of nipple breaks.
Flexural Strength
The force required to produce a flexural break (also called a break module). A high value reduces the number of electrode breaks.
Grade
Depends on the quality of the raw material (coke) used in the manufacture of graphite electrodes. The classification may vary among the world’s producers.
Young’s Modulus
It is a measure of resistance to the change of length before a tension or compression force. This modulus of elasticity is expressed as the relation between force (force per unit area) and the resulting deformation (change in length per unit length). A low value is usually associated with a good resistance to thermal shock.
