What are the industrial applications of silicon carbide?
Steelmaking
In electric arc and induction furnaces, B-SiC 0–10mm provides consistent silicon release for deoxidation. Its precise particle size ensures rapid and uniform dissolution, improving steel quality and minimizing slag contamination.
Foundry Operations
For cast iron and ductile iron, these grains improve graphite formation, reduce inclusions, and ensure more uniform mechanical properties in castings. The 0–10mm range offers flexible handling for dosing across different furnace types.
Ferroalloy and High-Temperature Processes
B-SiC grains are suitable for ferroalloy production, helping to control alloy composition with precision. High-purity grains ensure fewer impurities, optimizing performance in demanding high-temperature reactions.
What is the metallurgical mechanism of silicon carbide?
Black Silicon Carbide grains release silicon and carbon into molten metal at high temperatures. Silicon serves as an effective deoxidizer, while carbon participates in reduction and alloying reactions. The uniform grain size 0–10mm ensures even distribution in the melt, reducing losses and stabilizing the reaction rate.
Compared to larger or irregular grains, this controlled size range improves efficiency, minimizes dust, and enhances overall metallurgical process control.
