Q1: What is the main difference between Calcined and Graphitized Coke?
A: Graphitized Coke undergoes an additional high-temperature treatment, which increases its crystallinity. This results in faster absorption, higher carbon yield, and significantly lower nitrogen content, making it ideal for advanced applications like ductile iron and low-nitrogen steel.

Q2: How do I choose the right particle size?
A: Smaller particles dissolve faster but may have higher risk of loss. Larger particles are better for deep ladle addition. The optimal size depends on your furnace/ladle geometry and practice. We provide consulting to help you decide.

Q3: Can you customize the product specification?
A: Yes. We can tailor the fixed carbon, sulfur, and particle size distribution to meet unique process requirements. Contact us to discuss custom solutions.

Q4: What's your minimum order quantity (MOQ)?
A: For standard grades, MOQ is typically 1 container (20-24 MT). Trial orders and smaller quantities can be discussed.
