Ferrosilicon-magnesium nodulizer introduces magnesium so graphite can form as spheroids rather than flakes. The commercial grade must fit the foundry’s actual treatment method and base iron condition.
A high-magnesium alloy may reduce addition weight but can create a more intense reaction. Lower-magnesium or controlled-calcium grades may suit other ladle and cover practices. Rare-earth level should be selected for the charge quality and casting section, not treated as a universal quality indicator.
Quotation data
- Base iron sulfur and treatment temperature
- Sandwich, tundish-cover, wire or other treatment method
- Target residual magnesium and recovery experience
- Required Mg, Ca, RE, Si and Al limits
- Lump size, fines tolerance and packing
Because nodulizer is not the same as inoculant, list both requirements separately. Hyborton can coordinate the relevant foundry alloy inquiry through the contact page.
