Post‑calcined coke carbon‑addition agents are widely used in steelmaking, ironmaking, metallurgy, casting, and the automotive brake‑pad industry. They offer stable performance, low impurity levels, and tightly controlled particle size, enabling rapid carbon addition and improved production efficiency. Particle size and packaging can be customized to meet customer specifications.

As the “heart” of the aluminum electrolysis cell, the prebaked anode serves both as a current‑carrying electrode and as a participant in the electrochemical reactions of aluminum production, making it one of the most critical components of the aluminum electrolysis process. Calcined petroleum coke is one of the primary raw materials used to manufacture prebaked anodes, and its quality directly influences the anode’s physicochemical properties and the stability of the production process.

Resistance-grade and insulation-grade materials refer to calcined petroleum coke of varying particle sizes, named according to their intended use in the electrode or negative‑pole graphitization process. Typically, resistance-grade material is selected with a particle size of 8–25 mm, while insulation-grade material is chosen with a particle size of 0–2 mm.

Carbon powder refers to petroleum coke with a particle size of 0–1 mm after sieving.

Graphitized petroleum coke is produced by subjecting calcined petroleum coke to high‑temperature graphitization at 2,500–3,000 °C, resulting in a material with high carbon content and low levels of sulfur and nitrogen. Typically, sulfur content is below 0.05% and nitrogen content is below 300 ppm. It is widely used in the steelmaking and foundry industries, offering rapid dissolution and high absorption rates.

Graphite powder and graphite scrap are screening fines derived from graphitized petroleum coke, as well as cutting and crushing residues from graphite electrodes. Due to the high-quality raw materials used in their production and multiple stages of pressing and calcination, these products exhibit high carbon content, low sulfur levels, and a high specific gravity, making them widely employed in the steelmaking and foundry industries.
