Ferro Silicon 75% Natural Block

What Problems This Product Solves

1.Lower Cost Than Sized Lumps – Pay Only for Function, Not Extra Screening​ – Natural block keeps original fracture size; you avoid surcharge for tight 10–50mm or 50–100mm sorting when your furnace/ladle accepts varied lump sizes.

2.Si ≥75% Ensures Predictable Recovery​ – Same high Si content as FeSi75 sized grades, giving you confidence in alloy calculation and Si correction without switching grades.

3.Flexible Size Matching on Request​ – Though supplied as natural block, we can loose-screen to common ranges (10–100mm / 50–100mm / 10–50mm mix) to fit your charging system.

4.Batch COA Controls Impurity Risk​ – Al, Ca, P, S checked per lot; low-Al version available if your steel spec demands it.

5.Ideal Feedstock for Further Processing​ – Large natural lumps can be crushed in-house to granules or powder, saving you money on pre-sized material for inoculation/injection.

1.Steelmaking Initial Deoxidation​ – Added at tap or early ladle stage to remove dissolved O and form SiO₂ slag.

2.Furnace Si Adjustment​ – Bulk Si correction before final alloy trim; suitable when tight size not critical.\

3.Foundry Furnace Charge​ – Induction/cupola melt Si addition for gray/ductile iron.

4.Feedstock for Crushing to Granule/Powder​ – Large natural lumps re-crushed for inoculation or injection use.
