What is Silicon Carbide 90%?
Silicon Carbide 90% (SiC 90%) is a cost-effective metallurgical material widely used in steelmaking and casting. It contains approximately 90% silicon carbide, combining both silicon and carbon elements, making it an efficient alternative to traditional deoxidizers such as ferrosilicon.
Compared with higher purity grades, SiC 90% offers a better balance between cost and performance, especially for steel plants seeking to reduce raw material expenses without sacrificing quality.
Why Use Silicon Carbide Instead of Ferrosilicon?
In modern steelmaking, more buyers are shifting from ferrosilicon to silicon carbide due to its economic and technical advantages.
First, silicon carbide contains both silicon and carbon, meaning it can perform dual functions: deoxidation and carburization. This reduces the need for additional carbon additives.
Second, SiC improves slag fluidity and reduces oxidation loss, which directly enhances furnace efficiency.
Most importantly, using silicon carbide 90% can reduce overall steelmaking costs by 10–15%, making it highly attractive for bulk procurement.
Applications of Silicon Carbide in Steelmaking
Silicon Carbide 90% is widely used in:
Steelmaking (as deoxidizer and carburizer)
Foundry casting (improves casting quality)
Electric arc furnace (EAF) operations
Converter steelmaking
Slag conditioning
For steel plants, SiC is particularly effective in improving recovery rates and stabilizing production.
