Ferrosilicon 75 lumps is a commonly used alloy material, mainly composed of silicon and iron. Its "75" usually refers to the silicon content, that is, the mass fraction of silicon is about 75%. This alloy has a high silicon content, which can significantly increase the hardness and strength of steel, so it is widely used in the steel smelting process.

Product sizes typically include: 0-3mm, 0-10mm, 10-50mm, and 10-100mm, and can be customized according to customer needs.

The main features of ferrosilicon 75 lumps include

High silicon content:

The silicon content is as high as 75%, giving it good deoxidation and alloying capabilities.

Enhance the performance of steel:

Adding ferrosilicon 75 lumpss can improve the mechanical properties, wear resistance and corrosion resistance of steel.

Widely used:

In electric arc furnace steelmaking, it is used to adjust the chemical composition of molten steel, especially when the silicon content needs to be increased.

Melting point and density:

Ferrosilicon has a high melting point, usually above 1400°C, and a high density, which requires special equipment and technology during processing.

Performance Advantages

High Deoxidation:

Silicon has a strong affinity for oxygen, resulting in high deoxidation efficiency and significantly reducing the inclusion content in steel.

Cost Optimization:

Compared to other deoxidizers (such as aluminum and titanium), ferrosilicon is relatively affordable, effectively controlling steelmaking costs.

Good Stability:

Chemically stable, it resists deterioration during storage and transportation.

Wide Adaptability:

The composition can be adjusted to suit different steel grades and process requirements to meet diverse production requirements.

Market and Price

Market Dynamics:

China is the world's largest producer and exporter of ferrosilicon. The market price of FeSi75 natural lump is approximately 5,300-5,450 yuan/ton, and the price of the main futures contract fluctuates between 5,600-5,950 yuan/ton.

Price Influencing Factors:

Raw Material Cost:

Fluctuations in the prices of quartz sand and coke directly impact production costs. Energy Prices: Electric arc furnace smelting consumes a lot of electricity, and electricity price fluctuations have a significant impact on prices.
