Factory Direct Low Price High Quality Carbon

Carbon Raiser, also known as carbon additive, is a key material in steelmaking, casting, and other metallurgical processes. It is primarily used to increase the carbon content in molten steel or cast iron, compensating for carbon loss during melting. Our Carbon Raiser is produced with high fixed carbon, low sulfur, and low ash content, ensuring clean performance, high absorption efficiency, and stable product quality. It is widely applied in induction furnaces, electric arc furnaces, and cupola furnaces to improve efficiency and reduce costs.

Typical specifications of Carbon Raiser:

Fixed Carbon (FC): 90% – 98%

Sulfur (S): ≤ 0.3% / ≤ 0.5% (depending on grade)

Ash Content: ≤ 1% – 3%

Volatile Matter (VM): ≤ 1%

Moisture: ≤ 0.5%

Sizes: 0–1mm, 1–5mm, 1–10mm, or customized

The carbon absorption rate measures how efficiently carbon is absorbed by molten steel or iron. High-quality Carbon Raiser, such as Graphite Petroleum Coke (GPC), can achieve an absorption rate of 90–95%, depending on furnace type, temperature, and particle size. In comparison, coal-based carbon sources have a much lower absorption rate due to high ash and volatile content. Choosing a high-purity Carbon Raiser ensures better recovery and reduced material waste.

Yes. Carbon Raiser is particularly effective in induction furnaces because:

Fast Absorption: High temperature and controlled conditions allow carbon to be absorbed quickly.

Low Energy Waste: Efficient recovery reduces melting time and power consumption.

Consistent Quality: Induction furnaces require precise chemical balance, and Carbon Raiser ensures stable carbon levels.

Reduced Slag Formation: Low ash and impurities minimize slag, improving furnace efficiency.

For foundries using induction furnaces, factory-manufactured Carbon Raiser is the preferred choice.

Carbon content is one of the most critical factors affecting steel and cast iron performance. By adding Carbon Raiser:

Hardness & Strength: Higher carbon content improves strength and wear resistance.

Toughness: Controlled carbon levels balance ductility and toughness.

Graphite Formation: In cast iron, Carbon Raiser enhances graphite morphology, improving machinability.

Durability: Optimized carbon ensures longer service life of steel and cast products.

In short, Carbon Raiser directly influences the mechanical properties, microstructure, and reliability of final products in metallurgy.
