**Raw material requirements for graphite electrodes**

As an important industrial material, graphite electrodes need to meet certain raw material requirements during the production process. The following are the main requirements for graphite electrode raw materials:

**1. Petroleum coke**

Petroleum coke is one of the main raw materials for graphite electrode production. Its quality directly affects the physical and chemical properties of graphite electrodes. Petroleum coke should meet the following requirements:

* **Purity**: The impurity content in petroleum coke should be as low as possible to avoid negatively affecting the conductivity and corrosion resistance of the graphite electrode.

* **Ash**: The ash content of petroleum coke should be controlled within a certain range to ensure the strength and stability of the graphite electrode.

* **Volatile matter**: The volatile matter content of petroleum coke also needs to be controlled to ensure the stability of graphite electrodes at high temperatures.

**2. Needle coke**

Needle coke is a key raw material for the production of high-power and ultra-high-power graphite electrodes. The requirements are as follows:

* **Crystallinity**: The crystallinity of needle coke should be high to ensure that the graphite electrode has good electrical and thermal conductivity.

* **Particle morphology**: The particle morphology of needle coke should be needle-shaped, which helps to improve the structural stability and high temperature resistance of graphite electrodes.

**3. Coal pitch**

Coal pitch acts as a binder in the production process of graphite electrodes. Its requirements for raw materials include:

* **Softening point**: The softening point of coal pitch should be appropriate to ensure sufficient adhesion during the graphite electrode forming process.

* **Viscosity**: The viscosity of coal pitch should also be controlled within a certain range to facilitate uniform distribution during the graphite electrode forming process.

* **Impurity content**: The impurity content in coal pitch should be as low as possible to reduce the impact on the performance of graphite electrodes.

**4. Graphite particles**

Graphite particles are an important component of graphite electrodes. The requirements for raw materials are as follows:

* **Purity**: The purity of graphite particles should be high to ensure the conductivity and corrosion resistance of graphite electrodes.

* **Particle size distribution**: The particle size distribution of graphite particles should be reasonable to ensure the structural uniformity and stability of the graphite electrode.

**5. Wide graphite**

Wide graphite is an important raw material for the production of graphite electrodes of special sizes. The requirements include:

* **Dimensional Stability**: The size of wide graphite should be stable to ensure that the graphite electrode produced is accurate in size.

* **Structural Uniformity**: The structure of wide graphite should be uniform to ensure uniform performance of graphite electrodes.
