Product Introduction
75% Ferro Silicon Deoxidizer Alloy Additive Description
FeSi75 Ferro Silicon is an iron-silicon alloy used when your steelmaking process needs high silicon addition, final deoxidation and stable alloy composition adjustment. With Si 75% min, it provides stronger silicon input than FeSi72 or FeSi65, so your plant can reach the target silicon level with a relatively lower total alloy addition amount.
This grade is more suitable when your production focuses on high silicon addition, final deoxidation and ladle composition adjustment. In actual charging work, FeSi75 is not only selected because the Si number is higher. Your team also needs stable lump size, low fines, controlled Al/Ca/P/S values and clear batch COA, otherwise weighing loss, dust and inconsistent addition may still appear during furnace or ladle feeding.
We supply FeSi75 in 10–50mm, 10–100mm and customized size ranges for steelmaking use. For each order, we can help you check Si 75% min, Al, Ca, C, P, S, lump condition, packing method and shipment documents. If your plant uses FeSi75 for final deoxidation or high silicon correction, send us your required size, impurity limits, quantity and destination port, and we will match the suitable batch before quotation.

FAQ
Q: What is FeSi75 ferro silicon used for?
A: FeSi75 ferro silicon is used for high silicon addition, steel deoxidation, final deoxidation, ladle refining and molten steel composition adjustment.
Q: Why choose FeSi75 instead of FeSi72?
A: You can choose FeSi75 when your steelmaking process needs higher silicon input. Compared with FeSi72, FeSi75 provides more silicon per unit weight, so your plant may need a lower total addition amount to reach the same silicon target.
Q: Is FeSi75 suitable for final deoxidation?
A: Yes. FeSi75 can be used for final deoxidation when your process needs stronger silicon addition and stable composition adjustment during ladle refining or molten steel treatment.
Q: What is the silicon content of FeSi75?
A: FeSi75 usually contains Si 75% min. Actual batch values should be checked by COA before shipment.
Q: What size FeSi75 can you supply?
A: Common sizes include 10–50mm and 10–100mm. Custom size can also be discussed according to your furnace feeding or ladle addition method.
Q: Why is 10–50mm FeSi75 commonly used?
A: 10–50mm lump size is easier for weighing, furnace feeding and ladle addition. It also helps reduce excessive dust compared with material containing too many fines.
Q: What chemical elements should I check before buying FeSi75?
A: You should check Si, Al, Ca, C, P and S. These values affect steelmaking impurity control and should match your plant's internal standard.
Q: Can you provide COA before shipment?
A: Yes. We can provide batch COA so your team can check Si 75% min, Al, Ca, C, P and S values before shipment.
Q: How is FeSi75 packed for export?
A: Standard export packing is usually 1MT jumbo bag. Small bags, pallet packing, custom shipping marks and loading photos can be arranged according to your order.
Q: What information should I send for quotation?
A: Please send your required Si content, Al/Ca/P/S limits, size range, order quantity, packing method, destination port and trade term. We will help check suitable FeSi75 supply and quotation details.
