Ferro Alloys
By correct inoculation of cast iron the formation of chill can be prevented and gas related porosity and shrinkage to a great extent controlled and minimized.
Inoculants are specially designed FeSi based alloys to control the microstructure and mechanical properties of cast irons.

Silicon Manganese is used as a complex deoxidizer in steel production, and as reducer in the production of Low and Medium Ferro Manganese.
It can be used as a substitute for Ferro Silicon and Ferro Manganese when added to make different types of steel.
Both silicon and manganese have an important influence on the properties of steel, depending on the amount added and the combined effect with other alloying elements.

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. It is also used in the production of cast iron, as it can accelerate graphitization. Ferro Silicon replaces the need for ferro manganese, Spiegel Eisen and calcium silicide in the manufacturing process.

Ferro phosphorus is used mainly as the additives in the foundry industry to improve the floatability of foundry iron, thus improving the quality of the castings. Phosphorus content can increase the wearing resistance and improve the cutability in the castings. Ferro phosphorus also used as the additive in the steel production, which can improve the corrosion resistivity in certain steel
products.

Ferro-manganese is used mainly in the steel industry for hardening and desulphurisation of steel and as a deoxidizer, making the slag more fluid
Understandably, therefore, ferromanganese is the most widely used ferroalloy.

Ferro-chrome is added to steel to impart properties of hardness, strength and making it stainless. High Carbon Ferro Chrome is most commonly used in specialist applications such as engineering steels. Low-carbon Ferro-Chrome is used during steel production to correct chrome percentages. It is also a low cost alternative to metallic chrome for uses in super alloys and other special melting applications.
