What is ferro silicon?
Ferrosilicon is an iron alloy formed by the combination of iron and silicon. The silicon content is usually between 15% and 90% (the commonly used grade FeSi75 contains about 75% silicon). It is made by smelting in an electric furnace with coke, steel scraps and quartz as raw materials. Its main uses include steelmaking deoxidation, alloy additives and inoculants in the casting field.
What is the price of ferro silicon per kg?
5.35-6.00 yuan/kg (equivalent to 5350-6000 yuan/ton)
The price of ferrosilicon futures fluctuates in tons. For example, the spot contract price is 8,000 yuan/ton (about 8 yuan/kg), and the minimum change unit is 2 yuan/ton. The specific price needs to be adjusted in real time based on market supply and demand.
How do you make ferro silicon?
Process flow:
Raw materials: coke (reducing agent), steel scraps or iron ore (iron source), quartz/silica (silicon source).
Smelting: Silicon dioxide is reduced at high temperature in an electric arc furnace, and a chemical reaction generates ferrosilicon alloy.
What is the difference between silicon and ferrosilicon?
Silicon: A single chemical element (Si), which is active in nature and needs to be extracted through smelting.
Ferrosilicon: An alloy of silicon and iron, which is directly used for deoxidation or alloying in industry and has higher stability.
Is ferrosilicon toxic?
The existing data does not clearly mention toxicity, but dust pollution may be generated during the smelting process, and industrial protection standards must be followed.
