The production of ferro magnesium involves subjecting the elements to high temperatures, fostering a molten state where alloying occurs. This process results in a material with a complex crystalline structure, exhibiting properties distinct from its individual components. But based on ferro magnesium formula its composition is as bellow:
- Silicon (Si): 40-50%
Silicon is the primary element in ferro silicon magnesium and contributes to the deoxidation and graphitization of the iron.
- Magnesium (Mg): 4-15%
Magnesium is added to promote the formation of spheroidal graphite in ductile iron, improving its mechanical properties.
- Iron (Fe): Balance
Iron is the base metal, and the remaining composition is primarily iron to which the other elements are added as alloying agents.
- Calcium (Ca): 1.5-3%
Calcium is often added for desulfurization and to modify the shape of the graphite in the iron.
- Aluminum (Al): 1% max
Aluminum is used for deoxidation and can also help control the size and shape of graphite nodules.
- Total Rare Earth Elements (TRE): 0.5-20%
Rare Earth Elements (REE) are added to improve the nucleation of graphite and provide other beneficial effects. The specific composition of REEs can vary widely.
It’s important for manufacturers and users to specify the desired composition based on the properties needed for a particular application. The production of ductile iron involves careful control of the alloying elements to achieve the desired microstructure and mechanical properties.
