Nodulizer

Ferro silicon magnesium is a ferrosilicon alloy added by magnesium, calcium, manganese, and rare earth. It always refers to ferro silicon magnesium (MgFeSi) nodularizer.

Our company mainly supplies specialized 3-8 nodulizer, 5-8 nodulizers, and 7-8 nodulizer for ductile iron, ensuring product quality and timely supply. We can process various particle sizes according to customer requirements.

Nodulizer, nodulizing agent also known as ferro silicon magnesium, is an additive that can promote the crystallization of graphite in ductile cast iron into spherical shapes. It is generally used in the field of casting cast iron. During the casting process, the additive added to the molten iron to precipitate graphite in a spherical shape is called a spheroidizing agent. Spheroidizing agents containing rare earth elements are called rare earth spheroidizing agents;

Ferrosilicon magnesium is an alloy formed by melting ferrosilicon, calcium, magnesium, etc. It is a good nodulizer and has strong deoxidation and desulfurization effects. Ferrosilicon, rare earth minerals, and metallic magnesium are produced The main raw material of magnesium ferrosilicon alloy.

In China, the commonly used nodulizer is ferrosilicon rare earth magnesium alloy. Most foreign countries use magnesium-based nodulizing agent (pure magnesium and magnesium alloys), and a few countries use calcium-based spheroidizing agents.

The production of rare earth ferro silicon magnesium alloy is carried out in submerged arc furnaces, which consumes a lot of electricity. Medium frequency furnaces can also be used;

Function of ferro silicon magnesium

The main function of nodulizer is to improve the internal structure and performance of metal, especially in the field of casting. It can precipitate graphite in molten iron in spherical form, thereby producing high-performance ductile iron. Specifically, the addition of nodulizer can:

• Improve the internal structure of metal: Spheroidizing agents can promote the cooling and solidification process of molten metal, forming a finer and denser grain structure, improving the strength, wear resistance, corrosion resistance and fatigue resistance of castings and extending the life of castings.
• Improve the performance of castings: Nodularizing agents can reduce or eliminate casting defects, thereby improving the overall quality of castings.
• Reduce material costs: By effectively spheroidizing metals, spheroidizing agents can improve the utilization efficiency of metals, reduce material consumption, and thereby reduce production costs.
• Improve the cutting performance of metal: Nodularizing agents can reduce internal stress and improve the plasticity and toughness of metal, making the metal easier to cut and process.
• Prevent impurity interference: When the nodularizing agent interacts with low-melting-point impurities such as arsenic, zinc, lead, etc., it can generate iron-insoluble compounds with lower melting points, thereby eliminating the interference of these impurities and protecting the spheroidizing effect.

Application of ferro silicon magnesium nodulizer

1. Nodulizing agent, vermicularizing agent and inoculant for cast iron. Rare earth magnesium ferrosilicon alloy, also known as magnesium alloy spheroidizing agent, is a good inoculant with high mechanical strength and strong deoxidation and desulfurization effects;
2. Additives for steelmaking: Light rare earth magnesium ferrosilicon alloys are used in the production of nodulizing agents, creeping agents, and inoculants. They are also used as additives and alloying agents in the production of steel and iron. Used for refining, deoxidation, denaturation, neutralization of harmful impurities with low melting points (Pb, arsenic, etc.) and solid solution alloying to form new metal compounds, etc. to purify steel;
3. Used for refining, deoxidation, denaturation, neutralization of harmful impurities with low melting points (Pb, arsenic, etc.) and solid solution alloying to form new metal compounds to purify steel;

Ferro Silicon Magnesium Price On March 2024

Within Inner Mongolia, the cash-inclusive tax factory prices for rare earth magnesium range from 8000 to 8500 yuan per ton for 3-8 specifications and 8700 to 9200 yuan per ton for 5-8 specifications. In Jiangsu province, the cash-inclusive tax factory prices for rare earth magnesium range from 10000 to 10500 yuan per ton for 3-8 specifications and 10300 to 10800 yuan per ton for 5-8 specifications.

The price of raw material 90% magnesium ingot remains relatively stable at around 18000 yuan, while 95% magnesium ingot is priced up to 19000 yuan. However, the cost of raw materials has been weak, affecting the overall magnesium product chain. Both upstream and downstream sectors are experiencing weakness, leading downstream purchasers to be cautious. Additionally, it cannot be ruled out that some enterprises may lower prices due to their own financial pressures, which requires monitoring whether market transactions improve at the beginning of the week.

It is understood that following the continued decline in rare earth magnesium prices, some traders and downstream foundries have postponed purchasing plans or continued to lower their inquiries, resulting in stagnant market transactions with most participants adopting a wait-and-see approach.
