Product Introduction
Product Introduction
FeSi 72 lumps are a common type of ferrosilicon, an iron-silicon alloy containing about 72% silicon, with iron as the balance element and controlled levels of Al, Ca, C, S and P. The material is supplied in lump form, which makes it suitable for bulk furnace charging, weighing and storage in metallurgical production.
FeSi 72 grade ferrosilicon is used when your production needs a stable silicon source for alloy composition adjustment. The 72% silicon content provides a stronger silicon input than lower ferrosilicon grades, while the lump shape helps reduce excessive fines during handling and feeding. This makes FeSi72 suitable for steel plants, foundries and alloy producers that need controlled silicon addition in regular production.
You can use FeSi 72 lump ferrosilicon when your process needs consistent Si content, practical lump size and controlled impurity levels for furnace addition or alloy adjustment.

FAQ
Q:What is FeSi72 ferro silicon used for?
A:FeSi72 ferro silicon is mainly used for stable silicon addition, alloy composition adjustment and furnace addition. It helps your production control silicon input during steelmaking, foundry or alloy preparation.
Q:Is FeSi72 only used as a deoxidizer?
A:No. FeSi72 can be used for deoxidation, but this grade is also important for silicon content adjustment and controlled alloy addition. For this page, we focus on its stable silicon addition function.
Q:What lump size can you supply?
A:Common sizes include 10–50mm and 10–100mm. We can also confirm other sizes according to your furnace feeding, storage and packing requirements.
Q:What should I check before buying FeSi72?
A:You should check Si content, Al, Ca, S, P, C limits, lump size, powder ratio, packing method, COA and MSDS. If you have a target steel grade or application, you can send it to us before quotation.
Q:How do you pack FeSi72 ferro silicon for export?
A:FeSi72 ferro silicon is usually packed in FIBC jumbo bags. Waterproof packing or customized export packing can be confirmed according to your order, destination and storage conditions.
