HONGSHUN FeSiMg Nodulizers for Superior Ductile Iron

Ferro silicon magnesium, also known as FeSiMg alloy, is a remelting alloy made up of Ferro silicon, Magnesium, rare earth, and Calcium.
As an additive, it can crystallize the graphite in cast iron into a ball shape. Its’ main elements are Si, Mg, Re, Ca, etc. The silicon magnesium alloys containing rare earth elements are divided into ordinary rare earth nodularizer and yttrium base heavy rare earth nodularizer.

FeSiMg Key Uses:

• Deoxidizer for Steelmaking

• Inoculant and Nodulizer for Cast Iron

• Alloying Agent

Application in Ductile Iron Production:

Nodulization is a vital process in the production of ductile iron, where graphite is transformed from flakes into a spheroidal (round) shape during the solidification phase. This transformation significantly enhances the mechanical properties of cast iron, making it more ductile, durable, and resistant to fracture. A material known as a nodulizer, containing elements like magnesium (Mg), cerium (Ce), calcium (Ca), and barium (Ba), facilitates this change by influencing the formation of spheroidal graphite.

HONGSHUN specializes in Ferro Silicon Magnesium (FeSiMg) nodulizers, designed specifically to meet the needs of ductile iron foundries. These nodulizers contain precise amounts of magnesium and other elements like cerium (Ce), which work synergistically to ensure uniform graphite formation. Magnesium is the key element that initiates the spheroidal shape of graphite, while silicon plays a pivotal role in preventing carbide formation and controlling the release of magnesium.

Product Range and Advantages:

HONGSHUN offers two main types of FeSiMg nodulizers:

• 5.0-5.50% Mg

• 5.50-6.00% Mg

• 9.5-10.0% Mg

These products are specially formulated for foundry applications, ensuring consistent nodulization and excellent quality in the final cast iron products. By adjusting the magnesium content according to the specific production requirements, foundries can achieve precise control over the graphite morphology, leading to improved mechanical properties like tensile strength, elongation, and impact resistance.

Additional Benefits:

• High Efficiency in Nodulization: The controlled release of magnesium ensures complete absorption, minimizing losses and maximizing efficiency.

• Improved Cast Iron Quality: Ductile iron produced with FeSiMg nodulizers from HONGSHUN offers superior mechanical performance, making it suitable for a wide range of industrial applications, including automotive parts, pipes, and heavy machinery.

• Custom Solutions: HONGSHUN can customize FeSiMg nodulizers to meet specific foundry requirements, offering flexibility in product formulations and magnesium content.

With a long history of delivering high-quality ferroalloy products, HONGSHUN ensures that its FeSiMg nodulizers provide reliable and consistent performance, helping manufacturers achieve optimal results in ductile iron production.
