- Submerged Arc Welding Flux: Acts as an effective deoxidizing agent, improving weld metal purity and mechanical properties.
- Cored Wire Electrodes: Used in the core formulation to enhance arc stability and weld bead appearance.
- Manual Electrodes (Stick Electrodes): Enhances arc ignition and slag removal, increasing welding efficiency.
- Thermal Spray Coatings: Applied in wear-resistant and corrosion-resistant surface engineering.
(2) Use of Atomized Ferrosilicon Powder in Other Industries
- Foundry Industry: Serves as an alloy additive to improve casting strength and ductility.
- Metallurgical Industry: Used during steelmaking to adjust chemical composition and refine grain structure.
3. Chemical Composition of Ferrosilicon Powder (Typical Values)
| Element | Content Range |
|---|---|
| Si | 43%-47% |
| Fe | Balance |
| Al | ≤1.0% |
| Ca | ≤0.5% |
| Mn | ≤0.5% |
| C | ≤0.2% |
| P | ≤0.03% |
| S | ≤0.03% |
The controlled composition ensures that Ferrosilicon Powder maintains high purity and low levels of harmful elements like phosphorus and sulfur, contributing to improved weld quality and structural integrity.
