The specification of ferrosilicon 75 usually refers to fesi alloy with a silicon content of 75%. It is an alloy composed of iron and silicon elements, which is widely used in steel smelting, especially in the fields of steel deoxidation, alloying and manufacturing silicon steel. FeSi 75 has a high silicon content, so it has strong deoxidation ability and alloying effect, and is often used in the manufacture of steel products with higher requirements.

Physical Form & Size

FeSi75 is available in various forms to suit different applications:

Lumps:

Common sizes: 10–50 mm, 10–100 mm, 50–100 mm.
Tolerances: ≤5% of particles <10 mm or >60 mm (standard), with tighter limits (≤8%) for specific orders.

Granules:

Sizes: 3–10 mm, 1–3 mm, 0–3 mm.

Powder:

Mesh sizes: 325 mesh (≤45 μm) or custom.
Packaging: Typically in 25 kg bags, 1-ton bags, or 20-foot containers for export, with moisture-proof liners to prevent oxidation.

Characteristics of ferrosilicon 75

Silicon content: 75%, which means that there are 750 kg of silicon elements in each ton of ferrosilicon.

Form: It is usually sold in the form of granules, blocks or ingots, which is convenient for adding to molten steel for smelting.

Application areas of Ferrosilicon 75

Steel smelting:

It is widely used as a deoxidizer in the steel smelting process. Deoxidation is an important step in steel production. It can remove oxygen from molten steel and improve the quality of steel.

Silicon steel production:

Used to produce silicon steel (such as electrical steel), which is widely used in the manufacture of power equipment, transformers and motors.

Foundry industry:

In the casting process, It can be used as an alloying element to improve the properties of cast iron.

Alloying agent:

Used for alloying special steel grades, especially in the manufacture of highly corrosion-resistant or high-temperature-resistant alloy steels.

Market price of Ferrosilicon 75

The price of FeSi 75 is affected by many factors, such as raw material costs, electricity prices, production processes, market demand, etc. Generally speaking, the price of FeSi 75 will fluctuate between US$1,100 and US$1,300 per ton. The specific price is determined based on market conditions, origin, supply and demand, and the negotiation results between buyers and sellers.

Factors affecting prices

Raw material costs:

Price fluctuations of silicon ore and iron ore directly affect the production cost of fesi.

Electricity costs:

The production of ferrosilicon requires a lot of electricity, especially when smelted by electric arc furnaces. The fluctuation of electricity costs has an important impact on the price of ferrosilicon.

Market demand:

Changes in demand in the global and regional steel industry will directly affect the demand for ferrosilicon, and thus its price.

International supply chain:

In particular, China, as the world's largest producer and consumer of fesi, has an important impact on the global price of ferrosilicon due to changes in production and demand.
