Industrial FeSi 65 For Metallurgical Use

 

Industrial FeSi 65 for Metallurgical Use is a ferro silicon grade with Si 65% min, designed for metallurgical operations that require controlled silicon addition. It can be used for steel refining, alloy correction and other processes where a defined silicon-bearing ferroalloy is required.

The value of FeSi 65 is not determined by silicon content alone. Al, S and P limits, particle size, batch consistency and the way the material is introduced into the furnace should also match your production requirements.

For an actual order, confirm the required chemistry, particle size, quantity, packing and inspection documents before quotation. The final supplied material should be evaluated against the agreed specification and batch quality documentation rather than only the commercial grade name.

If you need to compare FeSi 65 with other silicon grades, you can also review our ferro silicon product range.

 

The current FeSi 65 specification controls silicon together with aluminum, sulfur and phosphorus. Particle size and packing are also part of the commercial specification and should be confirmed before the order is finalized.

Specification Category	Technical Parameters	What to Confirm for Your Order
Silicon (Si) Content	Min. 65%	Confirm against your target silicon addition and melt chemistry.
Aluminum (Al) Content	Max. 2.0%	Compare with your maximum allowable Al input.
Sulfur (S) Content	Max. 0.02%	Check against the sulfur limit required by your process.
Phosphorus (P) Content	Max. 0.04%	Confirm that the phosphorus level meets your acceptance standard.
Optional Particle Sizes	50–100 mm / 1–10 mm	Select according to furnace feeding and handling requirements.
Packaging Specifications	1000 kg Ton Bags	Confirm packing and net weight before shipment.

If your internal standard uses tighter Si, Al, S or P limits, send the required chemistry before quotation. We can compare your specification with the available FeSi 65 material before confirming supply.

 

FeSi 65 for Steel Refining

FeSi 65 can be used when your refining process requires a controlled silicon-bearing ferroalloy addition. The required dosage should be calculated from the starting melt chemistry and the target silicon level rather than from the grade name alone.

FeSi 65 for Alloy Correction

When silicon in the melt needs adjustment, FeSi 65 can provide a defined silicon input. Before use, compare Si, Al, S and P with the chemical limits required by your final steel or alloy specification.

FeSi 65 for General Metallurgical Operations

This grade can also be considered for other metallurgical operations where a 65% silicon ferroalloy matches the production requirement. If your process needs a different silicon level or tighter impurity control, another FeSi grade may be more appropriate.

 

Silicon Content

The Si 65% min specification defines the main alloying value of the product. Your required addition amount depends on the existing silicon content in the melt, the target composition and the recovery conditions of your process.

Aluminum Control

Al is listed at 2.0% max in the current reference specification. If your process has a tighter aluminum limit, state the required maximum before ordering rather than assuming all FeSi 65 material uses the same Al specification.

Sulfur and Phosphorus Limits

S and P should be checked separately against your internal steelmaking standard. A batch that meets Si 65% can still be unsuitable if another controlled element falls outside your acceptance range.

 

The current specification lists two available particle-size ranges. Size should be selected according to your charging method, furnace configuration and handling requirements.

Particle Size	Supply Consideration
50–100 mm	Larger lump specification for suitable furnace charging conditions.
1–10 mm	Smaller particle specification where finer material is required.

If your production uses another particle-size range, include it in the inquiry so availability can be confirmed before quotation.

 

 

Chemical Composition Verification

For FeSi 65, batch acceptance should include more than the silicon result. The agreed Si, Al, S and P values should be checked together against the purchase specification.

• Si: confirm the minimum silicon content.
• Al: verify the maximum aluminum limit.
• S: compare sulfur with your process acceptance limit.
• P: confirm phosphorus against the agreed specification.

Particle Size Screening

Particle size should be checked against the range confirmed in the order. This is particularly important when your furnace feeding system is designed for a specific lump or granular size.

COA and Batch Acceptance

If you require a batch COA or quality certificate, state this before order confirmation. The useful acceptance sequence is:

Your internal specification → confirmed FeSi 65 specification → actual batch test result.

If your purchasing procedure includes third-party inspection, sampling rules or a specific test method, send those requirements with the RFQ so they can be confirmed before shipment.

 

1000 kg Ton Bag Packing

The current FeSi 65 specification lists 1000 kg ton bags. If your warehouse, unloading method or transport plan requires another packing arrangement, include it in the inquiry before quotation.

Reference Transport Time

The existing product information gives a reference transport time of approximately 15–20 days, depending on destination and shipping schedule.

This should not be treated as a fixed delivery commitment for every order. Final timing depends on quantity, specification, packing, destination and the actual shipping arrangement.

 

If you are confirming FeSi 65 for a specific metallurgical process, provide the application conditions together with the target chemistry. This gives us a clearer basis for discussing the required grade and particle size.

Dosage and Silicon Adjustment

For silicon correction, provide the starting composition and target Si level. The required addition amount depends on your melt condition and process recovery.

Particle Size Selection

Tell us how the material will be charged into the furnace so the required particle-size range can be confirmed with the order.

Specification Matching

If your internal standard differs from the current FeSi 65 reference specification, send the exact chemical limits rather than only the product name.
