Product Introduction
Silicon-Barium-Calcium Flux-Cored Wire is a commonly used metallurgical material in steelmaking and casting. It is manufactured by encasing silicon-barium-calcium alloy powder within cold-rolled low-carbon steel strip to form a wire-shaped product. Its outer layer consists of low-carbon steel sheath, primarily serving to protect the core powder and ensure precise feeding. The inner layer comprises silicon-barium-calcium alloy powder, which constitutes the core functional component.
Primary Components
| Si (Silicon) | 40%–60%, primary deoxidizing element |
| Ba (Barium) | 5%–15%, performance enhancer, stabilizes calcium and improves yield |
| Ca (Calcium) | 5%–15%, strong deoxidizing and desulfurizing agent |
| Al (Aluminum) | Trace amounts (1%–3%), auxiliary deoxidizer |
Core Applications
1. Powerful Deoxidation: Synergistic deoxidation by silicon, calcium, and barium delivers significantly stronger performance than single silicon-calcium wires.
2. Deep Desulfurization: Reduces sulfur content to enhance steel ductility and toughness.
3. Grain Refinement and Molten Steel Purification: Improves steel strength, toughness, and surface quality.
4. Prevents nozzle scaling in continuous casting: Modifies inclusions for smoother production.
5. Dual function of inoculation and deoxidation: Suitable for inoculating cast iron grades to reduce white structure and refine microstructure.
Product Advantages
Deoxidation, desulfurization, and purification in one
More effective and stable than calcium-silicon wire
High recovery rate, economical usage, and controllable costs
Wide applicability: suitable for carbon steel, high-quality steel, and cast iron
Usage Method
Equipment
Wire Feeder
Timing
During tapping, in the ladle furnace (LF), or before continuous casting
Application
Use the wire feeder to rapidly insert the cored wire straight into the molten steel, ensuring it sinks deep and does not float on the surface.
Post-Addition
Gently stir with soft argon gas to facilitate full reaction and impurity flotation.
Purpose
Deoxidize, desulfurize, purify molten steel, and prevent nozzle blockage.
