Ferro Silicon(FeSi)
What is Ferro Silicon?
Ferro Silicon (FeSi) is a ferroalloy composed primarily of iron and silicon. It is one of the most important raw materials used in the steelmaking and metallurgical industries, serving as a deoxidizer and alloying agent to improve the quality, strength, and performance of steel and cast iron products.
Produced in electric arc furnaces through the reduction of silica using carbon based reducing agents, Ferro Silicon is valued for its high silicon content, consistent chemical composition, and versatility across a wide range of industrial applications.
Ferro Silicon – Production Process
At Kinley Metal Private Limited, Ferro Silicon is manufactured using carefully selected raw materials and modern metallurgical processes. High purity quartz serves as the primary source of silicon and is combined with iron bearing materials and carbon reductants inside a submerged electric arc furnace.
The high temperatures generated within the furnace reduce silica into molten Ferro Silicon, which is then refined to achieve the required chemical composition. After refining, the alloy is cast, cooled, crushed, screened into various particle sizes, and packaged according to customer specifications.
Every stage of production is closely monitored to ensure consistent product quality, operational efficiency, and compliance with international standards.

Ferro Silicon Magnesium (FeSiMg)
What is Ferro Silicon Magnesium?
Ferro Silicon Magnesium (FeSiMg) is a ferroalloy containing iron, silicon, and magnesium, primarily used as a nodulizing agent in the production of ductile iron. It plays a critical role in modifying the shape of graphite inclusions in molten iron, transforming them from flakes into spherical or nodular forms.
By promoting the formation of nodular graphite, Ferro Silicon Magnesium improves the mechanical properties, strength, toughness, and durability of cast iron products. Its controlled chemical composition and consistent metallurgical performance make it an essential material for modern foundry operations.
Ferro Silicon Magnesium – Production Process
At Kinley Metal Private Limited, Ferro Silicon Magnesium is produced using carefully selected raw materials and controlled metallurgical processes. Ferro Silicon serves as the base alloy and is combined with magnesium and other alloying elements according to the required chemical composition.
The alloying process is carried out under controlled conditions to ensure proper incorporation and distribution of magnesium within the Ferro Silicon matrix. The resulting alloy is then cast, cooled, crushed, screened into different sizes, and packaged according to customer requirements.
Throughout the production process, quality parameters are closely monitored to maintain consistent composition, product performance, and suitability for foundry applications.
