Coal Based Recarburizer CAC Calcined Anthracite

Calcined Anthracite Coal (CAC), also known as coal based recarburizer or carbon raiser, is manufactured by high-temperature calcination of high-quality anthracite above 1200℃. The calcination process removes moisture and volatile matter, delivering stable high fixed carbon, low sulfur, low ash and low volatile content. It serves as an economical carbon additive widely adopted in steelmaking and foundry industries to adjust carbon content in molten metal.

Key Advantages

✅ High fixed carbon, high carbon absorption rate, stable carburizing effect

✅ Low sulfur & low ash, less impurities, reduces slag generation

✅ Low volatile matter, less smoke and gas during melting ✅ Dense particle structure, good thermal stability, not easy to powder

✅ Cost-effective alternative to graphitized petroleum coke, cuts smelting cost

✅ Multiple particle sizes available for both furnace charging and injection feeding
