Ferro Silicon Nitride Lump For Steelmaking Nitrogen Alloying
Product Overview
Ferro Silicon Nitride Lump is a Fe-Si-N based alloy material used for steelmaking nitrogen alloying, special steel production and furnace addition. Compared with ferro silicon nitride powder used in refractory formulas, lump and granular material are more suitable when your process needs direct charging, alloy batching and controlled metallurgical feeding.
We supply ferro silicon nitride lump with typical Si3N4 70–80%, N 28–33%, Si 47–52% and Fe 12–16%. It can provide both nitrogen and silicon contribution in steelmaking, especially when your production needs a nitrogen-bearing alloy material instead of fine refractory powder.
Product Specification
| Chemical Parameter | Specification |
|---|---|
| Si3N4 | 70–80% |
| N | 28–33% |
| Si | 47–52% |
| Fe | 12–16% |
| Al + Ca | 2.5% Max |
The above chemical values are reference specifications for ferro silicon nitride lump. Actual Si3N4, N, Si, Fe and Al+Ca values should follow the delivered batch data. If your steelmaking process has stricter nitrogen, silicon or impurity requirements, please confirm your internal standard before order arrangement.

Product Applications in Real Production
Steelmaking Nitrogen Alloying
You can use ferro silicon nitride lump when your steelmaking process needs nitrogen input through a ferro alloy material. It is suitable for production routes where nitrogen is part of the alloy design and needs to be added in a controlled way.
In actual use, your team should calculate the addition amount according to nitrogen target, expected recovery, silicon contribution and furnace practice. The material should be selected by chemical content and feeding method, not only by product name.
Special Steel Production
For special steel production, ferro silicon nitride lump can support nitrogen and silicon adjustment when the steel grade requires controlled Fe-Si-N input. Granular or lump material is practical for plants that use direct furnace addition or batch alloying.
If your process has strict requirements for nitrogen control, the delivered batch data should be reviewed before use. Nitrogen content, silicon content, particle size and impurity tolerance all affect the final selection.
Furnace Addition and Alloy Batching
Ferro silicon nitride lump is suitable for furnace addition and alloy batching when your plant does not want to use fine powder. Granular sizes such as 3–5mm and 3–10mm can be used for smaller batching systems, while 10–50mm lump can be considered for wider furnace feeding.
The suitable size should follow your feeding method. Too many fines may cause dust and handling loss, while oversized material may not match your batching system. That is why size confirmation should be completed before shipment.

FAQ
Q: What is ferro silicon nitride lump used for?
A: Ferro silicon nitride lump is mainly used for steelmaking nitrogen alloying, special steel production, furnace addition and metallurgical alloy batching when nitrogen and silicon input are required.
Q: What is the difference between ferro silicon nitride lump and powder?
A: Lump or granular material is more suitable for steelmaking and furnace addition. Powder material is usually used for refractory formulas such as taphole clay, castable and refractory additives.
Q: What sizes of ferro silicon nitride lump can be supplied?
A: Common sizes include 3–5mm, 3–10mm and 10–50mm. Custom size can be discussed according to your furnace feeding or batching requirement.
Q: What chemical values should be checked before ordering?
A: You should check Si3N4, N, Si, Fe, Al+Ca, particle size and batch data before ordering. If your process has stricter impurity limits, the standard should be confirmed before quotation.
Q: How is ferro silicon nitride lump packed for export?
A: Standard packing is usually 1000KG FIBC jumbo bag. PE inner liner, moisture-proof packing, small bags, pallet packing, shipping marks and loading photos can be arranged according to order requirements.
