Ferro Silicon Magnesium Manufacturing Process – Why Nortech Leads the Industry in Quality and Innovation

 Crafting Metallurgical Precision with Technological Excellence

In the ever-evolving world of metallurgy, ferro silicon magnesium (FeSiMg) is one of the most crucial alloys used in transforming cast iron into ductile iron. This transformation enhances strength, toughness, and elasticity—making the material indispensable for industries such as automotive, pipe manufacturing, and heavy engineering.

At the forefront of delivering high-performance FeSiMg in India is Nortech Ferro Alloys Pvt. Ltd. Renowned for its commitment to quality, process mastery, and industry innovation, Nortech leads the ferro silicon magnesium manufacturing sector with precision, reliability, and forward-thinking solutions.

Nortech provides FeSiMg in various forms—powder, granules, or chunks—tailored to client furnace conditions.

🔍 What Is Ferro Silicon Magnesium?

Ferro silicon magnesium is an alloy composed primarily of silicon (Si), magnesium (Mg), and iron (Fe). It often contains small quantities of calcium (Ca) and rare earth (RE) elements to improve inoculation behavior and alloy performance.

This alloy is used primarily in the nodularization of graphite during ductile iron casting—allowing for better mechanical properties and improved performance under stress and pressure.

🏭 Nortech’s FeSiMg Manufacturing Process: Step by Step

Unlike generic suppliers, Nortech has developed a controlled, end-to-end production process that guarantees consistent composition, granule sizing, and metallurgical behavior.

1. Raw Material Sourcing

Only high-purity silicon, magnesium, and iron are selected. Sourcing partners are audited for elemental quality, moisture content, and trace impurities.

2. Melting and Alloying

• The raw materials are melted in electric arc furnaces.

• Silicon and iron are combined first.

• Magnesium is then added under controlled atmospheric conditions to minimize oxidation.

3. Alloy Refinement

Once alloyed, the mixture is subjected to:

• Stirring and slag removal

• Addition of calcium or rare earths for enhanced stability

• Real-time temperature and viscosity checks

4. Granulation and Cooling

The molten alloy is poured into granulation units or molds:

• Granule sizes are customizable

• Rapid cooling ensures uniform crystal structure

5. In-House Lab Testing

Each batch undergoes testing for:

• Magnesium content

• Silicon and RE levels

• Nodularization capacity

• Grain uniformity and inclusion control
