Ferro Silicon Barium With Stable Chemical Composition 40% FeSi75 For Iron Castings
- Maximum spheroidization.Encourage type A flake graphite formation in gray irons.
- maxmum chill reduction. Reduced relative hardness to improve machinability.
- Reduced fading tendency.
- reduced sectional sensitivity.
- Stable chemical composition.
- Low melting point(~1300) for easy absorption.
Applications:
The production practice indicated that it was available to decrease acid soluble aluminium content in alloyconstructional steel and spring steel and increase surface quality of products and reduce reject amount of bearing steel products because of D type inclusion by using bariumsiliconalloydeoxidizer partially to replace aluminium.
- Same as other Si base inocuant.
- 0.1-0.5mm is for late stream inoculation.
- Addition rare is about 40% of FeSi75
