Why Choose Silicon Carbide 90% 1–3mm for Metallurgical Applications?
Silicon Carbide (SiC) 90% with a 1–3 mm particle size is widely recognized in steelmaking and foundry industries for its ability to enhance deoxidation efficiency and improve molten metal quality. Its higher purity compared to lower grades reduces impurities like aluminum and iron, resulting in more predictable furnace reactions and superior casting performance.
For foundries and EAF operators, using this grade ensures faster dissolution, consistent silicon delivery, and reduced risk of defects, directly improving operational ROI.
What Are the Technical Specifications of SiC 90% 1–3mm?
| Parameter | Specification |
|---|---|
| SiC Content | 90% ±1% |
| Particle Size | 1–3 mm |
| Aluminum (Al) | ≤0.4% |
| Iron (Fe) | ≤0.3% |
| Carbon Content | ≥2.7% |
| Bulk Density | 2.8–3.0 g/cm³ |
| Moisture | ≤0.3% |
These specifications highlight the high purity and stable composition of SiC 90%, making it ideal for precision metallurgical processes.
How Does Particle Size Affect Performance in Steelmaking?
The 1–3 mm particle size offers a balance between rapid reaction and controlled silicon release. Smaller particles dissolve quickly, ensuring fast deoxidation and uniform silicon distribution. At the same time, slightly larger particles prevent overreaction and allow sustained silicon supply during longer furnace operations.
This particle range also minimizes dust loss during handling and transportation, reducing operational inefficiencies.
Why Is High Purity Important in SiC 90%?
High-purity SiC 90% ensures minimal contamination in the molten metal. Impurities such as iron or aluminum can increase slag formation, reduce silicon recovery, and compromise the mechanical properties of the final steel or cast iron product.
By using high-purity SiC, foundries can maintain stable furnace conditions, improve yield, and ensure consistent quality across multiple production batches.
