Nodularizer: Overview | Optimal Results & Best Supplier

What is Nodularizer?

nodularizer is an additive widely utilized in the foundry industry, primarily aimed at promoting the spherical crystallization of graphite in cast iron, thereby enhancing the distribution and efficiency of graphitization. The main chemical components of nodularizers include magnesium, rare earth elements, silicon, calcium, barium, and iron. Nodularizers containing rare earth elements and magnesium play a crucial role in ductile iron, significantly improving nodularization effects and preventing distortions in nodular graphite within thick-walled castings. There are currently several mainstream types of nodularizers, including magnesium ferro silicon based, rare earth magnesium silicon based, calcium based, nickel magnesium based, pure magnesium, and rare earth nodularizers, with silicon magnesium alloys being the most widely used, effectively enhancing the performance of ductile iron.

Applications of Nodularizers

• Grain Refinement: In the steel production process, molten steel gradually solidifies upon cooling, forming crystals. The use of nodularizers can effectively improve the shape and distribution of these crystals, facilitating grain refinement and enhancing the physical properties of castings.

• Improvement of Casting Performance: Nodularizers are effective in the liquid state of steel, reducing the liquid components and improving the fluidity and pouring characteristics of the steel. This results in smoother, more uniform surfaces in castings with fewer internal defects such as porosity.

• Enhancement of Mechanical Properties: The application of nodularizers can significantly enhance the hardness, strength, and toughness of steel, making it more durable and wear-resistant, thus meeting higher performance demands.

Specifications of Nodularizers

Casting Nodularizers

Casting nodularizers have lower impurities and higher absorption rates. XLS Metals produces highly pure nodularizers, employing stringent raw material selection and specialized production equipment based on extensive industry patents. Each batch of casting nodularizer is produced under strict standards, ensuring optimal nodularization effectiveness.

Different types of casting nodularizers are used for various applications. Low magnesium nodularizers containing 4%, 5%, and 5.5% magnesium, with rare earth elements (RE) at 1%-2%, are commonly employed in medium-frequency furnace applications for low-sulfur castings, providing advantageous nodularization reactions and smooth absorption of nodularization elements. Medium magnesium nodularizers (6%-7%) are primarily utilized in cupola furnaces or electric furnace dual smelting for pearlitic ductile iron castings. The appropriate amount of nodularizer is determined based on the casting wall thickness and sulfur content of the molten iron, ensuring broad applicability and diverse nodularization processes. High magnesium nodularizers are suitable for melting in cupola furnaces with sulfur levels at 0.06%-0.09%, requiring addition rates between 1.6%-2.0%. Low-aluminum nodularizers are utilized for castings prone to sub-surface porosity defects and specific aluminum content requirements. Pure Ce and La-produced nodularizers lead to cleaner molten iron with fewer inclusions and well-rounded graphite nodules. Yttrium-based rare earth nodularizers are ideal for large cross-section castings, delaying nodularization decline and preventing chunky graphite.
