Ferro Silicon In Cast Iron Industry

Ferrosilicon is a necessity in the steelmaking and foundry industries. During the production process, excess oxygen needs to be removed to produce steel and castings with better strength and toughness. During this process, an appropriate amount of ferrosilicon needs to be added to promote deoxidation and reach the oxygen content that meets the qualified standards.

Since silicon and oxygen easily combine to form silica, ferrosilicon is often used as a deoxidizer in steelmaking. At the same time, since SiO2 releases a large amount of heat when it is generated, it is also beneficial to increase the temperature of molten steel while deoxidizing. At the same time, ferrosilicon can also be used as an alloying element additive and is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel, and electrical silicon steel. Ferrosilicon is often used as a reducing agent in ferroalloy production and the chemical industry.

At the same time, the addition of ferrosilicon can also improve the shape of inclusions and reduce the content of gas elements in molten steel. It is an effective new technology to improve steel quality, reduce costs, and save iron. It is especially suitable for the deoxidation requirements of continuous casting molten steel. The practice has proved that ferrosilicon not only meets the deoxidation requirements of steelmaking but also has desulfurization performance and the advantages of large specific gravity and strong penetrating power.
