Ferro Silicon 75% in Steel Making

Ferrosilicon alloy is a deoxidizer and alloying agent in the steelmaking industry. In order to ensure the quality of steel and obtain steel with qualified chemical composition, deoxidation must be carried out in the final stage of steelmaking. The chemical affinity between silicon and oxygen is very large, so ferrosilicon is a powerful deoxidizer in steelmaking for precipitation and diffusion deoxidation. Adding a certain amount of silicon to steel can significantly improve the strength, hardness, and elasticity of steel. Therefore, when smelting structural steel (containing 0.40-1.75% silicon), tool steel (containing SiO.30-1.8%), spring steel (containing SiO.40-2.8%), and silicon steel for transformers (containing 2.81-4.8% silicon), and also use ferrosilicon as an alloying agent. In addition, in the steelmaking industry, since ferrosilicon powder can emit a lot of heat at high temperatures, FeSi is often used as a heat-generating agent for box-hat to improve the quality and recovery rate of steel ingots.

FeSi 75% Granule for Casting

FeSi 75% is commonly used as an inoculant and nodularizer in the cast iron industry. Cast iron is an important metal material in modern industry. It is cheaper than steel, easy to melt and smelt, and has excellent casting performance and shock resistance. In particular–nodular cast iron, its mechanical properties are close to steel. Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbides in iron and promote the precipitation and spheroidization of graphite. Therefore, in the production of nodular cast iron, ferrosilicon is an important inoculant (helping to precipitate graphite) and nodulizer.

FeSi alloy 75% for Reductant

Ferrosilicon alloy is used as a reducing agent in ferroalloy production. Due to the high chemical affinity between silicon and oxygen, and the low carbon content of high-silicon ferrosilicon, high-silicon ferrosilicon is a common reductant in the production of low-carbon ferroalloy.

Ferrosilicon 75% for Metallurgy

Ferrosilicon 75% is often used in the Pidgeon process for magnesium smelting and is added in the high-temperature smelting process of metallic magnesium. To replace the magnesium in CaO.MgO, about 1.2 tons of ferrosilicon will be consumed for every ton of magnesium metal produced. Ferrosilicon plays a great role in the production of magnesium metal.

About the Production Cost and Price of 75# Ferrosilicon

Ferrosilicon is made of coke, steel scrap, and silica (or quartz) through electric furnace smelting, then one ton of ferrosilicon needs 1.75 tons of silica (cost 100 yuan), 8500 to 9000 kWh (cost 3570 to 3780 yuan) about 1-ton semi-coke, 230 kilograms of steel, and many other things.

In the smelting of ferrosilicon, the raw material silica actually does not account for a large cost, because we have ferrosilicon raw ore and do not need to rely on imports, and the cost of electricity accounts for the largest cost of ferrosilicon smelting. One ton of ferrosilicon will probably consume 9000 kWh of electricity, so many manufacturers choose to build factories and smelt in areas rich in electricity resources. However, this year, due to external factors such as the new crown epidemic, the changing international situation, border trade frictions, and other external factors, coupled with internal reasons such as environmental protection, electricity, and energy restrictions. As a steel mill, the supply of high-grade iron ore in steelmaking or casting will definitely be affected.

We should pay attention to the composition index required by ferrosilicon in casting and steelmaking is different.  Generally, the models of ferrosilicon are 75A, 75B, and 75C. 75A refers to ferrosilicon with a silicon content above 75, 75B refers to ferrosilicon with a silicon content between 72-74, and 75C refers to ferrosilicon with a content between 65-72, The silicon content is different, and the effect achieved is also different. The price difference is also very great, so be sure to pay attention to these issues when purchasing ferrosilicon.
