Low Price Carbon Raiser Manufacturer Factory

Carbon Raiser, also called carbon additive, is a vital material used in steelmaking, casting, and other metallurgical industries to increase the carbon content of molten metal. It ensures that steel and cast iron reach the desired chemical composition, improves mechanical properties, and reduces production costs. Our Carbon Raiser is produced under strict quality control, featuring high fixed carbon, low sulfur, low ash, and high absorption efficiency, making it ideal for a wide range of applications.

Typical specifications of Carbon Raiser:

Fixed Carbon (FC): 90% – 98%

Sulfur (S): ≤ 0.3% or ≤ 0.5% (based on grade)

Ash Content: ≤ 1% – 3%

Volatile Matter (VM): ≤ 1.0%

Moisture: ≤ 0.5%

Sizes: 0–1mm, 1–5mm, 1–10mm, or customized as per requirement

High Carbon Content: Ensures effective and stable carbon addition.

Low Sulfur & Nitrogen: Reduces steel defects and improves purity.

High Absorption Rate: Quick melting and efficient carbon absorption.

Low Ash & Impurities: Cleaner operation with minimal slag formation.

Adjustable Size Range: Suitable for different furnace types and processes.

During steelmaking and casting, carbon is often lost due to oxidation and reactions with oxygen in the furnace. Adding Carbon Raiser directly to the molten metal replenishes the lost carbon and increases the carbon content to the required level. This helps achieve better hardness, strength, wear resistance, and improved microstructure in steel and cast iron. High-quality Carbon Raiser also improves furnace efficiency by reducing energy consumption and minimizing the use of expensive alloys.

Selecting the correct grade depends on application requirements:

High-End Steelmaking: Use low-sulfur Graphite Petroleum Coke (GPC) for clean steel and stable quality.

Cast Iron Foundries: Choose Calcined Petroleum Coke (CPC) or coal-based Carbon Raiser for cost-effective carbon recovery.

Aluminum and Special Alloys: Natural graphite or premium GPC is recommended due to high purity.

General Purpose Steel Plants: Standard CPC with medium carbon and low ash provides the best balance between cost and performance.

👉 In general, consider fixed carbon level, sulfur content, particle size, and absorption rate when selecting the right grade for your process.
