The relationship and difference between ferrosilicon nitride and ferrosilicon

Ferrosilicon nitride is a composite material of silicon nitride, iron and ferrosilicon. It is usually directly nitrided from the ferrosilicon alloy FeSi75 at high temperature.

What is high carbon silicon, and what are the differences between silicon carbon alloy and ferrosilicon?

High-carbon silicon alloy is an alloy composed of silicon and carbon, also known as high-carbon silicon, which is ferrosilicon with a large carbon content.

Rare earth magnesium ferrosilicon alloy (commonly known as spheroidizing agent)

Rare earth magnesium ferrosilicon alloy is an alloy formed by melting ferrosilicon, calcium, magnesium, rare earth, etc. It is a good spheroidizing agent and has strong deoxidation and desulfurization effects.

Introduction to ferrosilicon particles

The ferrosilicon particle inoculant is formed by crushing ferrosilicon into small pieces of a certain proportion and filtering through a certain number of sieves. The small particles that are crushed and screened out with different particle sizes.

The difference between silicon metal and ferrosilicon

The biggest difference is that industrial silicon is silicon metal and ferrosilicon is an alloy product. Both are substances containing silicon. The difference is: industrial silicon is a simple substance in pure substances, which is obtained through industrial smelting. Ferrosilicon is an alloy, which melts silicon and iron elements together at a high temperature in a certain proportion to form a product that meets people's specific needs.

Why does steelmaking need deoxidation

In order to ensure smooth casting and rolling into qualified steel, a certain amount of deoxidizer is added to the molten steel for deoxidation at the end of smelting or during tapping, and an appropriate amount of alloy is added to adjust the chemical composition according to the requirements of the steel specification. Generally, there are silicon-manganese alloys, ferrosilicon, ferromanganese, ferro-aluminum, silicon-aluminum-barium-calcium, etc.

Ferrosilicon alloys and silicon metal have different uses

In summary, ferrosilicon alloys are mainly used in the steel industry, while silicon metal is used in the production of electronics, solar energy, and alloys.

Manufacturing process of ferrosilicon

Silicon iron is an alloy made from silicon and iron, which is widely used in the steel industry for its properties such as high silicon content, good resistance to oxidation and corrosion, and high temperature stability. The manufacturing process of silicon iron involves several steps, as outlined below:

What is the difference between silicon slag and ferrosilicon slag

Silicon slag generally refers to the remaining part of the raw ore after refining, and also contains a certain amount of silicon. There are many types of silicon slag, including industrial silicon slag, solar silicon slag, semiconductor silicon slag, and so on.

Can silicon carbon alloy replace ferrosilicon?

As an alloy variety for converters, silicon carbon alloys can replace ferrosilicon, silicon carbide, and recarburizers, reduce the amount of deoxidizers, and be used in deoxidation alloying processes for converter smelting. The effect is stable, and the chemical composition, mechanical properties and internal control quality of steel types are superior to traditional techniques.
