Ferro Silicon 70 Lumps for Practical Furnace Feeding

Ferro Silicon 70 lumps, also called FeSi70 ferro silicon, are iron-silicon alloy lumps containing about 70% silicon, with iron as the balance element and controlled levels of Al, Ca, Mn, Cr, P, S and C. The material is supplied in lump form, making it suitable for furnace feeding, bulk charging, weighing and storage in regular metallurgical production.

This grade is used when your production needs a practical silicon source that can be charged into the furnace more easily than excessive fine powder. The lump shape helps reduce material loss during handling and feeding, while the 70% silicon content supports regular silicon addition in steel plants, foundries and alloy production.

For this page, we focus on Ferro Silicon 70 lumps for practical furnace feeding. You can use this material when your process needs stable lump size, controlled chemical composition and convenient furnace operation, instead of a powder-heavy material that may create more dust, weighing loss or storage problems.

Practical Furnace Feeding

Ferro Silicon 70 lumps are suitable for furnace feeding when your production needs a material that is easier to weigh, charge and handle. Compared with excessive fine powder, lump material can reduce dust, material loss and feeding difficulty during regular operation.

Bulk Charging in Metallurgical Production

The lump form makes FeSi70 suitable for bulk charging in steel plants, foundries and alloy production. You can confirm the lump size before order according to your furnace feeding method, storage condition and material handling process.

Regular Silicon Addition

With about 70% silicon content, FeSi70 provides a practical silicon source for regular production. It is often selected when your process needs a balanced silicon input, convenient lump handling and controlled impurity levels.

Q:What are Ferro Silicon 70 lumps used for?

A:Ferro Silicon 70 lumps are used for practical furnace feeding, bulk charging and regular silicon addition in metallurgical production. With about 70% silicon content, this grade is suitable when your process needs a stable iron-silicon alloy in lump form for easier weighing, storage and furnace operation.

Q:Why choose lump form instead of fine powder?

A:Lump form is easier to handle during bulk furnace feeding. Compared with excessive fine powder, Ferro Silicon 70 lumps can help reduce dust, weighing loss and material loss during storage, transfer and charging. This makes it more practical for regular steel plants, foundries and alloy production.

Q:What size of Ferro Silicon 70 lumps can you supply?

A:Common sizes include 10–50mm and 10–100mm. We can also confirm other lump sizes according to your furnace feeding method, storage condition and material handling requirement before order.

Q:What chemical composition should I check before buying FeSi70?

A:You should check Si content, Al, Ca, Mn, Cr, P, S and C. For Ferro Silicon 70, silicon content is usually about 70% min, with iron as the balance element. We can provide batch COA for your confirmation before shipment.

Q:Is Ferro Silicon 70 suitable for furnace feeding?

A:Yes. Ferro Silicon 70 lumps are suitable for furnace feeding because the lump shape is practical for charging, weighing and bulk operation. If your process does not require very high silicon input like FeSi75, FeSi70 can be a balanced option for regular furnace use.

Q:How is Ferro Silicon 70 packed for export?

A:Ferro Silicon 70 lumps are usually packed in 1 MT FIBC jumbo bags. Waterproof bags or customized export packing can be confirmed according to your destination, storage condition and shipment requirement. We do not recommend carton-style packaging for this bulk ferroalloy product.

Q:Can you provide COA and MSDS for FeSi70?

A:Yes. We can provide COA, MSDS, invoice, packing list and shipping documents according to your order requirement. Before shipment, you can confirm the chemical composition, lump size, packing method and delivery terms with us.

Q:What information should I send before quotation?

A:You can send us your required grade, lump size, quantity, destination port, packing requirement and application. This helps us confirm whether Ferro Silicon 70 lumps match your furnace feeding process and export delivery needs.
