Industrial Silicon Carbide (SiC) - ZhenAn International
What is Industrial Grade Silicon Carbide?
In heavy industries such as steelmaking and large-scale foundry operations, the pressure to reduce material costs while maintaining high-quality outputs is constant. Traditional additives like ferrosilicon can be expensive and sometimes provide inconsistent deoxidation results.
ZhenAn's Industrial Silicon Carbide (SiC) serves as a robust, dual-purpose additive that enriches both silicon and carbon levels simultaneously. Known for its high thermal conductivity and chemical stability, our industrial-grade SiC is the preferred choice for global smelting plants seeking to maximize furnace efficiency and minimize slag volume.
Technical Parameters and Chemical Composition
ZhenAn provides a range of industrial SiC grades, typically categorized by their SiC purity to suit different furnace requirements (EAF, BOF, or Induction).
| Component | Industrial Grade 88% | Industrial Grade 90% | Industrial Grade 95% |
| SiC Content | ≥ 88.0% | ≥ 90.0% | ≥ 95.0% |
| Free Carbon (F.C.) | ≤ 4.0% | ≤ 3.0% | ≤ 2.0% |
| Fe2O3 | ≤ 2.0% | ≤ 1.5% | ≤ 1.0% |
| Moisture | ≤ 0.5% | ≤ 0.5% | ≤ 0.3% |
| Al2O3 | ≤ 1.5% | ≤ 1.2% | ≤ 0.8% |
Key Industrial Applications: Steel, Casting & Refractory
1. Steelmaking Deoxidation
Industrial SiC is an effective deoxidizer for molten steel. It reacts with oxygen more vigorously than ferrosilicon at high temperatures, leading to cleaner steel with fewer non-metallic inclusions.
2. Iron Foundry Inoculant
In gray and ductile iron casting, SiC acts as a powerful nucleating agent. It promotes the formation of graphite flakes or nodules, improving the mechanical properties and machinability of the final casting.
3. Refractory Raw Materials
Because of its high melting point (approx. 2700°C) and resistance to thermal shock, industrial SiC is widely used in making furnace bricks, kiln linings, and crucibles.
4. Slag Conditioning
It helps in maintaining slag fluidity, making the tapping process smoother and reducing the loss of valuable alloys into the slag.
How Industrial SiC Optimizes Smelting Costs
The use of Industrial SiC provides a clear economic advantage through its "dual-alloying" effect:
Carbon and Silicon Recovery: One unit of SiC provides both silicon and carbon, replacing the need for separate additions of petroleum coke and ferrosilicon.
Exothermic Energy: The chemical reaction of SiC in the melt is exothermic, which helps maintain the liquid temperature and reduces the electricity consumption of the furnace.
Higher Yield: Faster deoxidation leads to a higher recovery rate of other noble alloys like manganese or chromium.
Industrial SiC vs. Traditional Ferroalloys
| Feature | Ferrosilicon (FeSi) | Petroleum Coke | ZhenAn Industrial SiC |
| Function | Silicon Additive | Carbon Additive | Si + C Dual Additive |
| Cost per Ton | High | Low | Moderate (Highest ROI) |
| Reaction Speed | Normal | Slow | Fast / Exothermic |
| Slag Production | High | Minimal | Low |
Available Forms: Lumps, Briquettes, and Grains
To accommodate various charging systems, ZhenAn offers industrial SiC in multiple physical forms:
SiC Lumps (10-50mm): Best for initial charging in Electric Arc Furnaces (EAF).
SiC Grains (1-10mm): Ideal for ladle additions and induction furnace charging.
SiC Briquettes: Compressed balls (e.g., 50x30mm) for easy handling and uniform melting.
SiC Powder: Fine mesh for specialized refractory mixing or coating.

Packaging, Logistics, and FAQ
Q: Can industrial SiC replace 100% of ferrosilicon in my process?
A: In many cases, yes. However, a partial replacement (50-80%) is often the most common strategy to balance chemistry and costs. We can provide a calculation based on your current melt profile.
Q: How do you manage the moisture content for export?
A: We use moisture-proof jumbo bags (1mt) with thick inner liners to ensure the product remains dry during sea transit.
Q: What is your typical lead time?
A: For standard specifications, we usually ship within 7-15 days from the receipt of an order.
