Products Description
Silicon Carbon (Si-C alloy) is an advanced metallurgical material made by smelting high-purity quartz (SiO₂) and carbon-rich materials such as coke or anthracite in an electric arc furnace at high temperatures. It is widely used as a composite deoxidizer and carbon additive in both steelmaking and foundry industries.
Silicon Carbon combines the functions of ferrosilicon and recarburizers, making it an economical and high-performance replacement in a variety of metallurgical processes. Its unique chemical composition helps improve deoxidation efficiency, increase carbon recovery, and lower slag formation-all while reducing overall production costs.

Product Characters
🔹 High Deoxidation Efficiency: Silicon Carbon reacts readily with oxygen in molten metal, resulting in efficient deoxidation and a cleaner melt.
🔹 Excellent Carbon Recovery: The high carbon content contributes to consistent and effective carburization, improving molten metal quality.
🔹 Low Impurity Levels: Low sulfur and phosphorus ensure cleaner steel and ductile iron, reducing defect rates.
🔹 Thermal Stability: Performs well at high temperatures without decomposition, enhancing melting and alloying efficiency.
🔹 Cost Efficiency: Replaces multiple materials (like ferro silicon and carburizers), simplifying logistics and cutting raw material costs.
Why Choose Silicon Carbon Over Other Deoxidizers?
✅ Dual Functionality: Unlike single-purpose materials such as ferrosilicon or pure carbon, Silicon Carbon offers both deoxidizing and carburizing effects in one product, streamlining operations.
✅ Lower Slag Formation: Its reactions produce less slag compared to ferrosilicon, improving furnace efficiency and metal yield.
✅ Better Alloy Recovery: More efficient absorption of carbon and silicon during the melting process improves element recovery rates.
✅ Reduced Cost: Silicon Carbon is more economical per ton of finished steel, especially when replacing multiple additives.
✅ Improved Quality: Produces purer steel with fewer non-metallic inclusions, enhancing mechanical properties.
