Product Introduction

0.5–4 mm High-quality, low-sulfur petroleum coke is calcined at 1,300°C and then graphitized at 2,500–3,000°C to create Graphitized Petroleum Coke (GPC), a dark-gray, granular carbon-based substance. The product has an interior hexagonal layered graphite crystal structure and a shiny sheen. Excellent qualities include low impurity levels, good electrical conductivity, high thermal stability, and a constant carbon content of ≥98.5%, sulfur ≤0.05%, and ash ≤0.7%. Although the particle size is consistent (0.5–4 mm), it can be altered to satisfy particular client needs.

Product Advantages

1. High Purity and Ultra-low Impurities: Excellent sulfur, nitrogen, ash, and volatile matter metrics, together with a high fixed carbon content. It is appropriate for high-end metallurgical production since the levels of harmful impurities are substantially below industry norms, preventing contamination of steel and castings.

2. strong Absorption Rate and Low Loss: During metallurgy, a carbon absorption rate of more than 95% is made possible by the unbroken graphite crystal structure, which guaranties strong carbon activity. Both manufacturing costs and raw material waste are successfully decreased by rapid dissolving and thorough reaction.

3. Accurate and Stable Particle Size: Carefully regulated at 0.5–4 mm, the particles are homogeneous and have high flowability, guaranteeing clogging-free feeding. This ensures the stability of the product's composition and enables careful control of carbon pickup.

4. Stable Performance and Wide Applicability: Provides outstanding electrical/thermal conductivity, oxidation resistance, and resistance to high temperatures. It is appropriate for a variety of smelting and roasting operations since it does not readily break down or fracture at high temperatures.

5. Quality Enhancement and Process Optimization: Successfully improves the mechanical characteristics and graphite morphology of steel and castings. It makes it possible to use more scrap steel, uses less pig iron, improves smelting procedures, and raises the pass rate of completed goods.

Product Applications

1. Iron and Steel Metallurgy Industry: Used in the smelting of carbon steel, alloy steel, and special steel as a premium recarburizer. It stabilizes the chemical composition of the melt, improves strength, hardness, and homogeneity, and accurately modifies the carbon content of molten steel.

2. Foundry Industry: Optimizes graphite nodularization, refines grain structure, improves wear and impact resistance, and lessens casting flaws including porosity and sand holes. Used in the manufacturing of ductile iron, gray iron, and precision castings.

3. Rubber, Plastics, and Chemical Industries: This functional addition maximizes the physical characteristics of rubber and plastic goods while enhancing their wear resistance, electrical conductivity, and thermal conductivity.
