Product Introduction
Product Description
An outer wire coats highly reactive flux powder, primarily composed of silicon and magnesium with rare earth elements and trace calcium. Upon burning/melting, it supplements alloying elements while promoting spheroidization and inclusion modification. Features continuous feeding, clean on-site operation, and high utilization rate.
Product Features
- Combined Spheroidization and Alloying: The synergistic action of silicon and magnesium, enhanced by rare earth elements, efficiently promotes spheroidization and improves inclusion morphology.
- Rare Earth Enhancement: Rare earth components aid nucleation and inclusion passivation, enhancing metal microstructural uniformity.
- High Utilization Rate: The cored wire format minimizes dust and reduces oxidation/burn-off, yielding superior actual utilization compared to loose powder addition.
- Continuous Feeding: Coil-fed wire integrates with automated feeding equipment, facilitating batch and standardized production.
- Consistent Specifications for Easy Inventory Management: Stable coil length and weight simplify factory scheduling and accounting.
Usage Recommendations
- Conduct pilot tests: Perform small-batch trials based on target metal composition and furnace conditions to confirm feeding rates and effectiveness.
- Control feeding rhythm: Continuous or segmented feeding is acceptable; maintaining a steady speed promotes uniform absorption.
- Coordinate with process parameters: Monitor steel/iron temperature, stirring, and refining conditions, as these affect absorption rate and spheroidization effectiveness.
- Prevent moisture exposure: Moisture reduces core powder reactivity; ensure dry storage and unwinding operations.
- Safety and environmental considerations: Wire feeding is safer and generates less dust than loose powder, but protective gear and adequate ventilation remain recommended in the work area.
