Key Features & Benefits of calcium silicon wire
Effective Desulfurization & Deoxidation – Helps remove impurities (S, O) to improve steel cleanliness.
Inclusion Modification – Transforms harmful inclusions (e.g., Al₂O₃) into softer, spherical calcium aluminates, enhancing machinability.
Alloying & Composition Control – Adjusts calcium and silicon content to meet specific steel grades.
Improved Castability – Reduces nozzle clogging in continuous casting.
High Absorption Rate – Encapsulation minimizes oxidation, ensuring optimal calcium yield (typically 15–30%).
Applications of calcium silicon wire
Ladle Furnace (LF) / Secondary Refining – For refining high-quality steel.
Stainless Steel Production – Controls sulfur and oxide inclusions.
Special Alloys & Cast Iron Treatment – Enhances ductility and mechanical properties.
Specifications:
Diameter: 9–16 mm (common sizes: 13mm).
Core Composition: 30–35% Ca, 55–60% Si, with trace elements.
Wire Coating: Optional anti-rust or alloy-specific coatings.
Advantages Over Traditional Methods:
Compared to direct alloy addition, cored wire ensures deeper penetration, reduced slag formation, and precise dosing, lowering costs and improving consistency.
