Graphite Carbon Raiser

Graphite Carbon Raiser is a high-purity graphitized carbon additive designed to increase carbon levels in molten steel and iron with maximum absorption speed, minimal slag generation, and zero nitrogen porosity risk.

 

 

Indicator	Typical Range	Core Function
Fixed Carbon (FC)	98–99.5%	Determines carbonization efficiency and purity; reduces impurity introduction
Sulfur (S)	≤0.05%	Prevents hot shortness of molten steel and ensures steel toughness
Nitrogen (N)	≤0.02%	Suitable for stringent requirements of low-nitrogen steel and high-end wire rod
Ash Content	≤0.5%	Reduces slag volume and improves molten steel cleanliness
Graphitization Rate	≥90%	Complete crystal structure, enabling carbon absorption rate of 85–95%
Carbon Absorption Rate	85–95%	Significantly higher than ordinary carburizers (60–75%), cutting dosage and cost

 

 

Ultra-Low Ash & Volatiles
Extremely low ash content minimizes slag thickness on the molten pool surface, reducing skimming downtime and energy loss.

 

Graphitized Crystal Structure
High-temperature graphitization ensures rapid dissolution into liquid iron, preventing unburned carbon floating or local carbon segregation.

 

Nitrogen Control
Eliminates nitrogen pinholes and gas defect rejection rates in high-grade ductile iron and low-alloy steel castings.

 

Furnace Protection & Clean Melt
Free of corrosive chemical impurities, reducing erosion on acidic and neutral refractory furnace linings during high-temperature operation.

 

 

Granule Size Distribution: 0.2–1 mm, 1–3 mm, 1–5 mm, or custom mesh sizing to match specific charging mechanisms.

 

Fixed Carbon Grades: Tailored formulations from 98.0% to 99.5% based on target steel/iron purity requirements.

 

Flexible Packaging Format: 25 kg multi-layer paper bags, 1-ton jumbo bags, or moisture-sealed stretch-wrapped pallets.

 

Private Labeling: Custom printing of shipping marks, batch codes, and buyer branding directly on outer bags.

 

 

Raw Material Screening: Strictly selection of calcined petroleum coke subjected to graphitization temperatures exceeding 2800°C.

 

Lab Particle & Chemical Testing: Every production lot is sampled for Fixed Carbon, Volatiles, Ash, Sulfur, and screen size distribution.

 

Batch Identification: Every ton bag carries a unique production heat/lot code for complete backward traceability.

 

Pre-Dispatch Verification: Internal lab analysis data generated for each dispatch lot prior to loading.

 

 

Weatherproof Barrier: Double-layer PE lining inside outer woven bags prevents moisture absorption during transit.

 

Container Loading Protection: Heavy-duty palletizing with edge protectors to prevent bag rupture during high-seas sea freight.

 

Marking Compliance: Clear markings showing gross/net weight, lot number, handling icons, and country of origin.

 

 

31-Year Metallurgical Lineage: Established in 1995, we leverage over three decades of manufacturing experience and 22+ senior engineers to offer tailored alloy ratios and tight tolerance controls.

Scalable Output & Fast Delivery: 80,000+ m² manufacturing base with 8+ dedicated production lines, ensuring an annual output of tens of thousands of tons for bulk orders.

 

Advanced & Mechanized Production: Equipped with upgraded medium-frequency induction furnaces and fully automated workflows for consistent chemical uniformity.

 

Certified Quality Assurance: Full batch traceability under ISO 9001, ISO 14000, and GJB 9001 standards, backed by complete in-house lab testing.

 

Global Logistics & Export Reach: Proven export track record with reliable fulfillment, serving industrial clients across 86+ countries.
