Brief Introduction To Carbon Additive

Carbon Additive is a material used in smelting processes to increase carbon content; it is available for bulk ordering and customization.

Features of Carbon Additive

High Absorption Rate

Carbon Additive is made from high-temperature calcined materials with stable carbon structure, achieving an absorption rate of 85%–95%, reducing smelting time and carbon loss.

Low Ash & Low Sulfur

Ash ≤5% and sulfur ≤0.5%, helping reduce impurities in molten steel and improve casting purity and performance stability.

Quality Control

01.

Raw Material Testing

Testing of petroleum coke or anthracite for fixed carbon, ash content, and sulfur levels to ensure compliance with standards.

02.

Calcination Control

Precise control of temperature and duration during the high-temperature calcination process to ensure carbon structure stability.

03.

Particle Size Screening

Utilization of screening equipment to maintain particle size within a specified range (e.g., 1–5 mm).

04.

Finished Product Testing

Verification of fixed carbon (90%–98%), ash content (≤5%), and sulfur levels (≤0.5%).
