Ferro Silicon is an atomized alloy, which is formed by combining iron and silicon with a silicon content range of 15% to 90%. Ferro Silicon is a universal "heat-blocker" used in the production of carbon and stainless steels. This additive is used with other Ferro alloys in the deoxidizing process of steel, as well as in the production of silicon itself. Ferro Silicon is used in the production of cast iron, as Ferro Silicon can accelerate graphitization. Ferro Silicon replaces the need for Ferro manganese, spiegeleisen and calcium silicide in the manufacturing process. Ferro Silicon is mainly produced in India, China, Bhutan & USA.
Application: Used as a deoxidizer in Steel making, used in production of Silicon steel (ex: Steel used in Transformer Cores), and used in production of magnesium via Pidgeon process.
