Ferrosilicon(FeSi) is made from semi-coke, silica, steel chips, and other products as raw materials, and is smelted by continuous operation in an open or semi-closed reduction furnace. The appearance of ferrosilicon is silver gray with a metallic luster, which can be processed intoferrosilicon lump,ferrosilicon granule,orferrosilicon powder, according to customer requirements.
The main uses of ferrosilicon aredeoxidizersandalloying agentsforsteelmaking,inoculants, and nodularizing agents forcast iron, and are also widely used inmagnesium metalandchemical industries.
Chemical Composition: Si, Al, Ca, Mn, Cr, P, S, C, Fe, and other elements.
Size: 0-3mm, 3-10mm, 10-50mm, or as the customer required.
Packaging Details: 1mt or 1.25mt per big bag, and also can be customized as the customer requires.

Advantages of Ferrosilicon in Steel Production
• Used as a deoxidizer to increase the strength and hardness of steel.
• Lower the melting point of steel.
• Improve production efficiency.
• Reduce energy consumption and production costs.
Application of Ferrosilicon
• Deoxidizer: Ferrosilicon can ensure the quality of steel during the steelmaking process while being used as a deoxidizer for precipitation and diffusion deoxidation.
• Alloying Agent: Ferro silicon can significantly improve the strength, hardness, and elasticity of steel while adding it to steelmaking.
•InoculantandNodulizer: Ferrosilicon can be used as an inoculant and spheroidizer in the cast iron industry. The iron silicon alloy can prevent the iron to format carbides and concurrently promote the precipitation and spheroidization of graphite.
• Reducing Agent: High silicon ferrosilicon has a very low content of carbon, ferro silicon is a reducing agent for producing low-carbon ferroalloys in the ferroalloy industry.
• Magnesium smelting:75 ferrosiliconalloys are often used in the high-temperature smelting process of metal magnesium.
• Suspended phase: Milled silicon and atomized silicon can be used in the mineral processing industry as the suspended phase.
• Coating: Ferrosilicon powder can be used as a coating for welding rods.
Among the above usage, the steelmaking industry, the foundry industry, and the ferroalloy industry are the largest users, which consume more than 90% of ferrosilicon. Among the different grades of ferrosilicon,75# ferrosiliconraw materials are the most widely used. In the steelmaking industry, it takes about3-5kgof75# ferrosiliconto produce1Tsteel.
Factors Affecting the Price of Ferrosilicon
Ferrosilicon for Steelmaking
• Demand for ferro silicon
The steel industry is the most important downstream industry of ferroalloys. More than 60% of the downstream demand for ferrosilicon is in the steel industry. Therefore, the output of steel has a decisive impact on the price of ferro silicium, and the cyclicality of the steel industry also drives the cyclical fluctuation of the price of ferrosilicon.
• Export of ferrosilicon alloy
The ferro silicon suppliers in China are mainly sold to Japan, South Korea, United Arab Emirates, India, United States and Brazil. In 2021, with the recovery of the global economy in the post-epidemic era, overseas ferroalloy demand will be strong, and the price of ferroalloy will rise sharply.
• Steel tenders and ferrosilicon prices
The spot market price of ferro silicio is cross-referenced with the tender price of steel mills. The current price of ferrosilicon has a guiding role in the bidding time of steel mills. The timing of the tenders reflects mills’ expectations for future ferrosilicon prices. On the other hand, steel prices and purchase volumes also have a certain impact on ferrosilicon futures prices.
• Cost of ferrosilicon production
In the cost of ferrosilicon, electricity accounts for 60%-70%, which has the greatest impact on the cost of ferrosilicon; blue carbon accounts for 25%-30%; raw silicon dioxide accounts for 2%, and silica has little impact on the cost of ferrosilicon.
•Both energy consumption and production restriction policies
Ferroalloy smelting is a highly polluting and energy-intensive industry, and electricity costs account for a high proportion of its costs. In addition to production and supply costs, there is also the impact of the dual-control policy on energy consumption and the policy of curtailment of electricity and production. The short-term rise and fall of ferroalloy prices are often dominated by policy.
