Ferro Silicon Nitride FeSiN30 For Steelmaking And Refractory Materials

Ferro Silicon Nitride FeSiN30 is a stable nitrogen-bearing ferroalloy used in steelmaking, special steel production, refractory raw materials and high-temperature metallurgical applications. It combines silicon, nitrogen and iron in a practical commercial form, allowing buyers to introduce nitrogen while also benefiting from silicon contribution.

Compared with ordinary ferro silicon, FeSiN provides both silicon and nitrogen. Ordinary ferro silicon is mainly used for silicon addition and deoxidation, while Ferro Silicon Nitride FeSiN30 is selected when nitrogen alloying, nitrogen recovery, grain refinement and high-temperature performance are required.

This product is suitable for steel mill buyers, refractory material manufacturers, ferroalloy traders and purchasing managers who need reliable chemistry, controlled particle size and stable batch supply.

The following specification is a typical reference for FeSiN30. Final values should be confirmed by purchase contract and batch Certificate of Analysis. Low carbon, low phosphorus, low sulfur, particle size distribution and moisture control should be reviewed before bulk purchase.

Ferro Silicon Nitride for steelmaking is used when steel producers need both silicon and nitrogen contribution. In selected steel grades, nitrogen can support strengthening, microalloying response and microstructure control. The product is also used when buyers require more controlled nitrogen addition than relying only on gas-based nitrogen control.

FeSiN30 can support steel nitrogen alloying, nitrogen recovery, grain refinement and strength improvement when matched with the steelmaker's grade design and furnace route. Lumps may be used for furnace or ladle addition, while granules can be selected for controlled feeding.

Ferro Silicon Nitride FeSiN30 is used in special steel, stainless steel, heat-resistant steel, tool steel, structural steel and alloy steel applications where nitrogen control or silicon-nitrogen addition is required. In these steel systems, controlled nitrogen may contribute to strength, grain structure and process stability.

For buyers evaluating high nitrogen ferro silicon nitride, the final effect depends on steel chemistry, furnace practice, temperature control and downstream heat treatment. FeSiN30 should be selected according to actual nitrogen target, silicon requirement and impurity tolerance.

Ferro Silicon Nitride powder is used in refractory materials exposed to high-temperature metallurgical environments. Common applications include blast furnace taphole clay, iron trough castables and high-temperature refractory mixes. In these uses, FeSiN contributes silicon-nitrogen functionality and supports refractory performance under slag and metal contact conditions.

FeSiN for refractory materials is usually selected in powder form, such as 200 mesh, 325 mesh or customized particle size. Refractory buyers should confirm powder size distribution, moisture level, chemical composition and packing before ordering.

Ferro Silicon Nitride FeSiN30 can be supplied as lumps, granules or powder. Lumps such as 10–50mm are generally used for furnace or ladle addition. Granules such as 3–10mm are suitable for controlled feeding or more uniform addition behavior.

Powder grades are used for Ferro Silicon Nitride powder applications in refractory materials, cored wire and customized metallurgical addition. Powder buyers should pay special attention to particle size, moisture, flowability and storage conditions.

Quality control should focus on N content, Si content, low carbon level, low P, low S, particle size consistency, low moisture and batch-to-batch stability. For steelmaking, unstable nitrogen may affect alloying accuracy. For refractory production, inconsistent powder size or moisture can affect mixing and product uniformity.

A reliable Ferro Silicon Nitride supplier should provide batch COA and support inspection of chemistry, particle size, moisture and packing condition. SGS, BV or CCIC inspection can be arranged for buyers with strict quality systems.

Packing options include 25kg bags, 1MT jumbo bags or customized export packing. Moisture-proof packaging is recommended for powder and fine granules. Bag marks, batch numbers, inner lining, pallet requirements and container loading records can be arranged according to purchase contract requirements.

Export supply documents may include commercial invoice, packing list, batch COA and shipment documents. Particle size testing, moisture testing and loading photos can be provided when required.

To request a quotation for Ferro Silicon Nitride FeSiN30, please provide N content, Si content, particle size, packing method, application, destination port, trial order quantity and monthly consumption. For steelmaking use, specify whether the product is for nitrogen alloying, silicon addition, microalloying or controlled nitrogen recovery.

For refractory applications, please specify whether FeSiN30 will be used in taphole clay, iron trough castables, refractory mixes, cored wire or other high-temperature metallurgical materials.
