Is Ferro Silicon A Dangerous Product?

What is Ferro Silicon?

Ferrosilicon alloy is composed of silicon, iron, and other impurities such as carbon, aluminum, and so on.

Ferrosilicon is mainly used in the steel industry, casting iron, magnesium ingot production, mineral industry, and welding rod. The silicon content is from 15% to 90%.

Is Ferro Silicon a Dangerous Product?

Ferro silicon, silicon content of 30%-90%, is dangerous.

UN Number: UN1408

Name: Ferrosilicon

Risk Category: 4.3 (Danger in water), 6.1 (Toxicant)

Ferrosilicon reacts slowly with water to release hydrogen. Increased hydrogen concentration can easily burn or explode. Therefore, ferrosilicon belongs to dangerous goods, but the danger degree is low.

According to the provisions of the Ministry of Communications, ferrosilicon in the process of sea and land transportation, must handle the relevant procedures for the transport of dangerous goods.

How to Export Ferrosilicon Alloy.

Ferrosilicon exports mostly choose ton bag packaging, the bag should have a clear sign indicating that it is ferrosilicon.

How to Store Ferrosilicon?

Ferrosilicon needs to be stored in a dry space. If long-term storage is required, to avoid contact with water. A layer of wood can be laid under the ferrosilicon to separate it from the ground.

Ferro Silicon Uses

Silicon and oxygen combine easily to form silicon dioxide. Therefore, ferrosilicon is often used in steelmaking as a deoxidizer, and due to the release of a large amount of heat when SiO2 is generated, it is also beneficial to improve the temperature of molten steel at the same time. Ferrosilicon as alloying element additive. It is widely used in low-alloy structural steel, bonding steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. Outside ferrosilicon is commonly used as a reducing agent in ferroalloy production and chemical industry. The silicon content is 95%–99%. Pure silicon is commonly used to make monocrystalline silicon or to prepare nonferrous metal alloys.

Ferrosilicon is widely used in steel industry, casting industry and other industrial production. Ferrosilicon is an essential deoxidizer in steelmaking industry. In torch steel, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying agent in steelmaking. Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of steel, improve the permeability of steel, and reduce the hysteresis loss of transformer steel. The general steel contains 0.15%-0.35% silicon, the structural steel contains 0.40%-1.75% silicon, the tool steel contains 0.30%-1.80% silicon, the spring steel contains 0.40%-2.80% silicon, the stainless acid-resistant steel contains 3.40%-4.00% silicon, and the heat-resistant steel contains 1.00% ~ 3.00% silicon. Silicon steel contains 2% to 3% silicon or higher.

High silicon ferrosilicon or siliceous alloys are used in the ferroalloy industry as reducing agents for the production of low carbon ferroalloys. Adding ferrosilicon to cast iron can be used as inoculant of nodular cast iron, and can prevent the formation of carbide, promote the precipitation and nodulation of graphite, and improve the performance of cast iron.

In addition, ferrosilicon powder can be used as a suspended phase in the mineral processing industry, and as a coating for welding rods in the welding rod manufacturing industry. High silicon iron silicon can be used to prepare semiconductor pure silicon in the electrical industry, and can be used to manufacture silicone in the chemical industry.

In the steelmaking industry, about 3 ~ 5kG 75% of ferrosilicon is consumed per ton of steel produced.
