Chemical Composition
The 80% and 85% designations represent distinct SiC grades that should be specified separately in purchasing documents. While multiple metallurgical SiC grades are commercially available, impurity limits vary between products and applications. Buyers should specify SiC content along with required limits for free carbon, oxides, sulfur, phosphorus, iron, and moisture where applicable.
Size and Form Options
Particle size selection should align with charging system requirements and reaction kinetics. Commercial references include 0-10 mm, 1-10 mm, and 10-50 mm metallurgical SiC products. Finer particles enable more distributed addition, while larger particles are suitable for specific furnace charging applications.
Key Characteristics & Functions
Steel Deoxidation
Metallurgical SiC serves as an effective deoxidizing additive during steel treatment processes.
Silicon Addition
SiC contributes silicon to the melt and facilitates precise alloy chemistry adjustment.
Carbon Addition
The carbon component makes SiC ideal for combined silicon and carbon addition requirements.
Foundry Treatment
SiC is utilized in cast-iron production and can provide preconditioning or nucleation effects in appropriate foundry processes.
Primary Applications
- Steelmaking Deoxidation: Used during steel treatment where silicon-based deoxidation and carbon adjustment are required
- Foundry Treatment: Applied in iron foundries, including induction and cupola furnace applications
- Alloy Processing: Serves as a silicon and carbon source during selected alloy-processing operations
- Furnace Treatment: Particle form enables efficient addition to suitable furnace charging systems
