The Metallurgical Mechanism of SiC 88% Granules
In fast-paced steel plant environments, rapid oxygen removal is critical to quality. ZhenAn's 1-3mm Silicon Carbide 88% provides high surface-to-mass ratio, ensuring rapid deoxidation reaction at the slag-metal interface.
The reaction follows: SiC + 3[O] → SiO₂ + CO↑
The resulting CO gas provides gentle boiling effect, helping float microscopic non-metallic inclusions to the surface, significantly improving steel internal cleanliness.
Key Applications & Performance Benefits
Ladle Metallurgy & Chemistry Trimming
1-3mm grain size is industry standard for automated alloying systems. Uniform flowability prevents hopper bridging, ensuring exact Silicon and Carbon dosing for final chemistry adjustments.
Induction Furnace Conditioning
For foundries and specialty steel mills using induction melting, SiC 88% provides stable, low-nitrogen Silicon source. Creates reducing environment that protects Chromium and Manganese from slag loss.
Refractory Protection
By deoxidizing slag early in the process, SiC 88% granules make slag less chemically aggressive. Reduces corrosive wear on ladle refractory bricks, potentially extending lining life by 10-15%.

FAQ: Frequently Asked Questions
Is 1-3mm sizing better than 0-10mm lumps for ladle deoxidation?
Yes. For ladle trimming, 1-3mm size is superior because it dissolves almost instantly. Lumps (10-50mm) are better suited for primary furnace charge where they need to survive mechanical impact of heavy scrap.
How does SiC 88% impact the recovery of other alloys like Manganese?
By killing the slag early, SiC 88% creates reducing environment. This prevents Manganese and Chromium oxidation, leading to significantly higher and more predictable recovery rates for these expensive alloys.
Does using Silicon Carbide increase hydrogen levels in steel?
No. Silicon Carbide is dry, inorganic mineral. By deoxidizing the melt and creating CO boil, it can assist in removal of dissolved gases like hydrogen and nitrogen.
Can this material be used in automated pneumatic injection systems?
Absolutely. 1-3mm granules are specifically screened for high flowability. They do not clog or bridge in dosing hoppers, making them ideal for modern automated steelmaking facilities.
What is the Silicon Equivalent of SiC 88%?
For calculation purposes, 100kg of SiC 88% provides approximately 61kg of active Silicon and 26kg of Carbon. High concentration allows massive reduction in total additive weight required per heat.
Does ZhenAn provide third-party inspection (SGS/BV) for export?
Yes. While conducting rigorous internal testing for every batch, we facilitate independent third-party inspections at loading port to verify chemical purity and 1-3mm size distribution.
