Ferro silicon

Ferrosilicon is literally known as an alloy of iron and silicon. Ferrosilicon is a new type of alloy product. Because ferrosilicon exhibits good chemical properties in use, it is widely used in the industry.

Ferrosilicon is a ferrosilicon alloy made from coke, steel scrap, quartz (or silica) and smelted in an electric furnace. Since silicon and oxygen are easily synthesized into silica, ferrosilicon is often used as a deoxidizer in steelmaking, and at the same time, a large amount of heat is released during the formation of SiO2, and it is also advantageous to increase the temperature of the molten steel while deoxidizing. At the same time, ferrosilicon can also be used as an alloying element additive, 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 iron alloy production and chemical industry.

Application:

(1) in the steel industry used as deoxidizer and alloying agents.
(2) in the iron industry used as a nucleating agent and spheroidizing agent. Cast iron is a kind of important modern industrial metal materials, it is much cheaper than steel, easy to melt refining, excellent casting performance and seismic capacity is far better than steel. Especially the nodular cast iron, its mechanical performance at or near the steel mechanical property. Add a certain amount of silicon in cast iron can prevent iron in formation and precipitation of carbides, and promote the graphite spheroidizing, therefore in the nodular iron production, ferrosilicon inoculants is a kind of important separation graphite (help) and spheroidizing agent.
(3) used as a reductant in ferroalloy production. Not only chemical affinity between silicon and oxygen is very big, but also high silicon silicon carbon content is very low. So high silicon ferrosilicon (or siliceous alloy) is a low-carbon ferroalloy ferroalloy industry production more commonly used a reducing agent.
