HONGSHUN FeSiMg Nodulizers for Ductile Iron

Ferro Silicon Magnesium (FeSiMg) Uses

• Deoxidizer for Steelmaking

• Inoculant and Nodulizer for Cast Iron

• Alloying Agent

Application:

Nodulization is a critical process in cast iron production, aimed at controlling the material's structure and mechanical properties. This process transforms graphite from flakes into spheroidal shapes during solidification, improving the material’s ductility and strength. A nodulizer contains elements that promote the formation of spheroidal graphite, such as magnesium (Mg), cerium (Ce), calcium (Ca), and barium (Ba).

HONGSHUN supplies Ferro Silicon Magnesium (FeSiMg) alloys that include cerium (Ce) to enhance the combined effects of these elements. A sufficient amount of magnesium dissolved in the base metal is crucial to form spheroidal graphite. Meanwhile, silicon—acting as the primary graphitizing element—prevents carbide formation and stabilizes the release of magnesium.

HONGSHUN offers two grades of FeSiMg nodulizers specifically designed for producing nodular cast iron (ductile iron):

• FeSiMg with 5.0-5.50%, 5.50-6.00%, and 9.5-10.0% magnesium content.

These alloys ensure optimal graphite nodulization, improving the cast iron's mechanical properties.
