Al₂O₃: MAX 1%
Sulfur (S): MAX 0.15%
Moisture: MAX 0.5%
Grain size: 10–50 mm, MIN 90%
With a minimum SiC content of 90%, this product features low impurities: free carbon ≤1.5%, Fe₂O₃ ≤1.0%, S ≤0.05% and N ≤0.05%, ensuring no secondary pollution to molten steel. The 10-50mm block particles are dense, high-strength and dust-free, enabling smooth feeding and uniform reaction in the furnace, which avoids blockage and improves processing efficiency.
It serves three core functions in steelmaking: efficient deoxidation by decomposing Si and C to combine with oxygen in steel, stable carburization with higher carbon absorption rate than coke, and slag modification to reduce slag melting point and promote slag-steel separation. Packaged in 1000kg jumbo bags, it is convenient for hoisting and automatic feeding, meeting the large-scale production needs of steel mills.
