![Petroleum Coke Based Carburizer]()
Petroleum Coke Based CarburizerProduct Overview Our petroleum coke-based carburizer is a high-efficiency, low-sulfur carbon additive specially designed for the foundry and steelmaking industries. Made from premium petroleum coke
1. By Raw Material
(1) Petroleum Coke-Based Carburizer
Features: High carbon content (typically ≥98%), low sulfur (premium grade ≤0.5%), minimal ash, and high absorption rate (85-95%).
Applications: Premium casting (e.g., ductile iron, precision castings) and EAF steelmaking.
(2) Graphitized Carburizer
Features: High-temperature graphitization treatment ensures stable carbon structure, ultra-high carbon content (≥99%), extremely low sulfur (≤0.05%), and near-100% absorption.
Applications: Critical applications like automotive engine castings and specialty alloy steels.
(3) Coal-Based Carburizer (Anthracite/Coke)
Features: Cost-effective but with lower carbon content (90-95%), higher sulfur/ash (sulfur may exceed 1%), and moderate absorption (70-80%).
Applications: General gray iron or less stringent carbon requirements.
(4) Biomass Carburizer
Features: Derived from coconut shells/charcoal, eco-friendly but variable carbon content (80-90%); requires pre-treatment.
Applications: Small-scale foundries or green production initiatives.
2. By Physical Form
Granular (1–10mm): Standard for controlled dosing and uniform absorption.
Powdered (<1mm): Rapid dissolution in induction furnaces (may cause dust loss).
Briquettes/Pellets: Minimizes handling losses; ideal for bulk usage.
3. Key Performance Comparison
| Type | Carbon (%) | Sulfur (%) | Absorption (%) | Typical Use Cases |
|---|---|---|---|---|
| Graphitized | ≥99 | ≤0.05 | 95–100 | Premium castings, specialty steel |
| Petroleum Coke | ≥98 | ≤0.5 | 85–95 | Ductile iron, EAF steelmaking |
| Anthracite | 90–95 | 0.5–2.0 | 70–80 | General gray iron |
4. Selection Guide
Maximize Absorption: Prioritize graphitized or low-sulfur petroleum coke.
Cost Control: Coal-based options (monitor sulfur impact).
Sustainability: Biomass carburizers (verify consistency).
