🔥 What Is Calcined Anthracite Coal?

Calcined Anthracite Coal (CAC) is a high-purity carbon material produced by heating raw anthracite coal to temperatures above 1200°C in the absence of air. This thermal treatment removes moisture and volatile components, resulting in a dense, low-sulfur, high-carbon product.

📌 Key Properties:

• Fixed Carbon: 90–95%

• Sulfur Content: <0.25%

• Volatile Matter: <1.5%

• CAS Number: 8029-10-5

• Typical Sizes: 0–1 mm, 1–3 mm, 3–8 mm

🏭 Main Applications:

• Steelmaking: Used as a recarburizer to adjust carbon content in molten steel

• Foundry: Enhances graphitization and casting surface quality

• Electrode Production: Filler for carbon paste electrodes

• Refractory & Industrial Furnaces: Clean-burning carbon source

🔬 What Is Calcination?

Calcination is a thermal process in which a material is heated to high temperatures (typically 800–1500°C) to induce physical or chemical changes. It is performed either in the presence or absence of air, depending on the desired outcome.

🎯 Purpose of Calcination:

🏭 Common Uses:

• Calcined Anthracite Coal production

• Calcined Lime (CaCO₃ → CaO) for cement and steel

• Calcined Bauxite/Dolomite/Kaolin for refractories and ceramics

• Metal oxide preparation in metallurgy and chemical synthesis

Calcined Anthracite Coal is a high-purity carbon additive used primarily in steelmaking, foundry operations, and electrode production due to its high fixed carbon content (up to 95%), low sulfur (<0.25%), and low volatile matter.

🔥 What Is Calcined Anthracite Coal?

Calcined Anthracite Coal (CAC) is produced by heating raw anthracite coal to temperatures above 1200°C in the absence of air. This calcination process removes volatile components and moisture, resulting in a dense, carbon-rich material with excellent thermal and chemical stability.

🔒 Industries Where Calcined Anthracite Coal Is Mandatory

🏭 1. Steelmaking

• Why mandatory? CAC is used as a recarburizer to precisely adjust the carbon content in molten steel. Its low sulfur, high fixed carbon, and low volatile matter make it ideal for electric arc furnaces (EAF) and induction furnaces.

• Alternatives? Graphitized petroleum coke is purer but more expensive. CAC offers a balanced cost-performance ratio.

⚙️ 2. Foundry Industry

• Why mandatory? CAC enhances graphitization, reduces slag formation, and improves casting surface quality. It is essential in ductile iron and gray iron casting processes.

• Alternatives? Natural graphite or petroleum coke may be used, but often lack the consistency and purity of CAC.

🔌 3. Electrode Manufacturing

• Why mandatory? CAC is used in carbon paste electrodes for aluminum smelting and ferroalloy production. It provides high electrical conductivity and low reactivity, which are critical for stable performance.

• Alternatives? Graphitized coke is used in premium applications, but CAC remains the standard for cost-effective electrode mass.

🔥 4. High-Temperature Industrial Furnaces

• Why mandatory? CAC serves as a clean-burning carbon source with low ash and sulfur. It is used in refractory linings, ceramic kilns, and thermal processing units.

• Alternatives? Raw coal or low-grade carbon additives introduce impurities and reduce furnace efficiency.
