Silicon Carbide 90 (SiC 90%) - ZhenAn International
What is SiC 90%?
Steel and foundry manufacturers often face challenges such as unstable deoxidation, high alloy costs, and excessive slag buildup. These inefficiencies increase operational costs and affect the final product's quality.
ZhenAn's Silicon Carbide 90 (SiC 90%) offers a powerful and cost-effective solution. As a high-purity metallurgical additive, it enhances deoxidation efficiency, stabilizes chemical composition, and improves metallurgical performance-all while lowering costs compared to traditional ferroalloys.
Chemical Composition and Technical Parameters
ZhenAn's SiC 90 is produced to meet strict industrial standards, ensuring stable performance in high-temperature electric arc furnaces (EAF) and basic oxygen furnaces (BOF).
| Parameter | Specification (Grade 90) |
| SiC Content | ≥ 90.0% |
| Free Carbon (F.C.) | ≤ 3.0% |
| Fe2O3 | ≤ 1.5% |
| Al2O3 | ≤ 1.2% |
| Moisture | ≤ 0.5% |
| Bulk Density | 1.4 – 1.6 g/cm³ |
Key Industrial Applications of SiC 90
1. Steelmaking (EAF/BOF)
SiC 90 is used as a potent deoxidizer. It supplements or replaces Ferrosilicon (FeSi) to reduce oxygen levels and acts as a reliable carbon raiser to reach target chemistry.
2. Iron Foundry Applications
In casting operations, SiC 90 improves the graphite structure of cast iron and reduces slag formation. It serves as an efficient source of both silicon and carbon for induction furnaces.
3. Refractory Materials
Due to its high thermal conductivity and oxidation resistance, SiC 90 is an essential raw material for high-temperature furnace bricks and linings.
How SiC 90% Optimizes Steelmaking Efficiency
Metallurgical-grade silicon carbide performs a dual role that simplifies the smelting process:
Cleaner Steel: Silicon reacts intensely with oxygen ($2Si + O_2 \rightarrow 2SiO_2$), lowering total oxygen and reducing non-metallic inclusions.
Exothermic Heat: The reaction of SiC in the furnace releases heat energy, helping to maintain melt temperature and reducing electricity consumption.
Slag Conditioning: It improves slag fluidity, making the tapping process faster and cleaner.
Why Choose SiC 90 over Ferrosilicon?
| Additive | Primary Function | Cost-Effectiveness | Operational Complexity |
| Ferrosilicon (FeSi) | Silicon Additive | Moderate | Requires separate carbon source |
| Petroleum Coke | Carbon Additive | Low | Requires separate silicon source |
| ZhenAn SiC 90 | Dual Function (Si+C) | High | Simple (One-step addition) |
Available Particle Sizes and Customization
We provide customizable sizes to fit different furnace types and dosing systems:
1–10 mm: Ideal for ladle additives and high-reactivity charge.
10–50 mm: Standard size for EAF/BOF furnace charges.
0–3 mm: Used for mixing with other additives or in automatic dosing systems.
SiC Briquettes: Compressed for easy handling and uniform melting.
Key Benefits for Buyers and Plant Operators
Significant Cost Savings: Much lower cost per ton compared to using separate silicon and carbon sources.
Cleaner Output: Lower oxygen levels and less slag lead to higher quality, defect-free steel.
Simplified Inventory: One additive replaces several inputs, streamlining procurement and logistics.
Faster Reaction: Speeds up processing time and increases furnace yield.
