Products Description
Silicon Slag, also known as Ferro Silicon Slag, is a by-product generated during the production of ferro silicon alloys. It contains moderate silicon content and is widely used in steelmaking, foundries, and alloy production as a deoxidizer, flux, and heat-preserving additive. Its cost-effectiveness and stable performance make it a popular choice for improving metal quality and furnace efficiency.
Specification
| Parameter | Typical Value |
|---|---|
| Si Content | 25% – 60% |
| Al Content | 2% – 5% |
| Ca Content | 2% – 8% |
| S, P | ≤ 0.05% |
| Size | 0–10mm, 10–50mm, customized |
Silicon Slag can be supplied in powder, granular, or lump forms depending on application requirements.
