Product Introduction
Medium carbon ferrosilicon is a type of ferrosilicon alloy with a high silicon content and a relatively high carbon content. It is usually used in the steel smelting and casting industries. It is usually produced by blast furnace smelting or electric arc furnace smelting processes and is mainly used for alloying and deoxidation in steel.
The main components of medium carbon ferrosilicon include silicon (Si) and carbon (C), of which the silicon content is 60%~75% (common specifications are FeSi 65, FeSi 70), and the carbon content is 1%~3%. Impurities usually include sulfur (S), phosphorus (P), etc., with low content, which is usually controlled within the required range in steel production.

Advantages and characteristics of medium carbon ferrosilicon
Efficient deoxidation:
Medium carbon ferrosilicon has strong deoxidation ability, especially suitable for the production of high silicon steel and special alloy steel.
Significant alloying effect:
Silicon is an important element in many alloy steels. The use of medium carbon ferrosilicon can ensure the required silicon content in the steel.
Lower cost:
Compared with some other alloy additives (such as ferromanganese, ferrochrome, etc.), medium carbon ferrosilicon has a lower cost and is suitable for large-scale industrial production.
Improving the comprehensive properties of steel:
Including improving strength, hardness, corrosion resistance, etc., especially in the production of some high-performance steels, the addition of silicon is very important.
