High-Quality Silicon Slag for Steelmaking and Foundry Industries
Welcome to your trusted source for premium Silicon Slag - a cost-effective and high-performance material widely used in steel refining, deoxidation, and temperature control. Whether you are a steel producer, foundry operator, or raw material trader, we offer fast quotes, reliable supply, and consistent quality tailored to your industrial needs.
What Is Silicon Slag?
Silicon slag is a byproduct of metallic silicon or ferrosilicon production. It consists mainly of silicon dioxide (SiO₂) and silicon metal, with varying silicon content typically ranging from 40% to 70%. Due to its strong deoxidizing properties and low cost, it has become a popular alternative to pure silicon materials in steelmaking and casting processes.
Key Benefits
Cost-Effective Alternative
Silicon slag offers similar deoxidation performance to ferrosilicon at a significantly lower cost, helping you reduce production expenses without compromising quality.
Efficient Deoxidation
With high active silicon content, it effectively removes oxygen from molten steel, improving the cleanliness and mechanical properties of the final product.
Temperature Control
Helps regulate temperature during the steelmaking process, enhancing operational stability and energy efficiency.
Versatile Applications
Suitable for a wide range of uses including steel ingot production, alloy smelting, and foundry casting.
Typical Specifications
We offer various grades of silicon slag to meet different customer requirements. Below are our most commonly supplied specifications:
| Grade | Silicon Content | Size | Application |
|---|---|---|---|
| A | 60–70% Si | 10–100 mm | Steelmaking, deoxidation |
| B | 50–60% Si | 10–80 mm | Foundry, alloying |
| C | 40–50% Si | Powder or lump | General industrial use |
Custom sizes and packaging available upon request.
