Products Description
Carbon Raiser, also known as recarburizer or carbon additive, is a vital material used to increase the carbon content in molten metals, especially in steelmaking and iron casting. It plays a key role in adjusting the chemical composition, improving mechanical strength, and enhancing the quality of the final product. Our carbon raisers are made from high-quality raw materials such as graphite petroleum coke, calcined anthracite, or artificial graphite, offering high carbon content and low impurity levels.

FAQ
Q1: What's the difference between GPC and CPC carbon raiser?
🔹 GPC (Graphitized Petroleum Coke) has higher purity and better performance but is more expensive.
🔹 CPC (Calcined Petroleum Coke) is cost-effective with good carbon recovery.
Q2: What carbon recovery rate can I expect?
🧪 Typically between 90%–98%, depending on the furnace type and process conditions.
Q3: Can you provide customized sizing or packaging?
✅ Yes, we offer custom particle sizes and various packaging options like 25kg bags, jumbo bags, or bulk.
Q4: Do you offer technical support?
🛠️ Absolutely! Our team provides technical consultation to help select the right grade for your specific application.
Q5: What's the delivery time for international orders?
📦 Standard delivery is 7–15 days, depending on order size and destination.
