Product Introduction

Product Description

Low Grade Silicon Slag is a premium by-product of the metallurgical process, widely used to reduce costs in steelmaking and casting. Our slag features stable composition and strict impurity control, making it an economical alternative to primary ferro silicon. Whether used as a deoxidizer or filler, it provides significant supply chain cost advantages for customers.

Chemical Composition Table

Element	Content Range (Typical)
Si	40% - 65% (Customizable, e.g., 45%, 55%)
Fe	Balance
Al	< 2.0%
C	< 1.5%
S	< 0.05%
P	< 0.05%

Particle Size Specifications

Standard: 10-50mm (Lump), 0-3mm (Powder)

Customization: Adjustable distribution based on customer usage (e.g., casting or weighting) to ensure minimal powder.

Product Advantages

Cost Efficiency: More competitive pricing than high-purity ferro silicon, significantly reducing smelting costs.
