What Is Ferrosilicon
Sep 06, 2018

Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon is a ferrosilicon alloy made from coke, steel scraps, quartz (or silica) as raw materials by electric furnace smelting. Ferrosilicon is often used as a deoxidizer in steelmaking because silicon and oxygen are easily oxidized to form silicon dioxide. At the same time, because of the large amount of heat released during the formation of SiO2, it is also beneficial to increase the temperature of molten steel while deoxidizing. At the same time, ferrosilicon can also be used as an additive of alloy elements, widely used in low alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel, ferrosilicon in ferroalloy production and chemical industry, often used as reducing agent.

A ferroalloy consisting of iron and silicon (ferrosilicon is formed by melting silicon reduced at 1500-1800 degrees from silica, steel and coke into molten iron). It is an important alloy variety in smelting industry.
