Anyang Hongshun Industrial Co., Ltd.

Ferrosilicon-magnesium nodulizer is a ferrosilicon alloy containing magnesium, calcium, manganese, and rare earth elements. It specifically refers to MgFeSi nodulizers used in ductile iron production. Our company specializes in 3-8, 5-8, and 7-8 nodulizer series to ensure the quality and stable supply of ductile iron production. Custom particle sizes can be customized to meet customer needs. FeSiMg nodulizer (also known as ferrosilicon-magnesium alloy) is an additive that causes graphite in cast iron to crystallize into spherical shapes. Added to molten iron during the casting process, it promotes the precipitation of graphite into spheroids. Nodulizers containing rare earth elements are called rare earth nodulizers. Ferrosilicon-magnesium alloys are smelted from ferrosilicon, calcium, and magnesium, offering excellent spheroidization and strong deoxidation and desulfurization capabilities. Their primary raw materials include ferrosilicon, rare earth minerals, and magnesium. Rare earth ferrosilicon-magnesium alloys are commonly used as nodulizers in China, while magnesium-based nodulizers (pure magnesium and magnesium alloys) are more commonly used abroad, with a few countries using calcium-based nodulizers. Rare earth ferrosilicon-magnesium alloys are primarily produced in submerged arc furnaces, which consume relatively high energy. Medium-frequency furnaces are also suitable for smelting. Ferrosilicon-magnesium product models include 3-8 nodularizers, 5-8 nodularizers, and 7-8 nodularizers. Ferrosilicon-magnesium functional properties: Nodularizers primarily improve the internal structure and properties of metals. In particular, in casting, they can cause graphite in molten iron to precipitate in a spherical form, thereby producing high-performance ductile iron. Specifically, it can: Improve metal structure: promote the cooling and solidification process of molten metal to form a finer grain structure, improve the strength, wear resistance, corrosion resistance and fatigue resistance of castings, and extend service life. Improve casting performance: reduce or eliminate casting defects, improve the overall quality of castings. Reduce material costs: improve metal utilization and reduce material consumption through effective spheroidization. Improve cutting performance: reduce internal stress, improve metal plasticity and toughness, and make processing easier. Prevent impurity interference: react with low melting point impurities such as arsenic, zinc, and lead to form iron-insoluble compounds, eliminating impurity interference. Reasons for choosing Hongshun ferrosilicon and magnesium: Located in Anyang, Henan, a ferroalloy production base, with obvious advantages in industrial agglomeration, it focuses on the production of spheroidizers and can provide a series of products with magnesium content of 3-8%, 5-8%, and 7-8%. The particle size of 5-30mm can be customized. Direct factory operation without intermediate links, with significant price advantages. Provide third-party inspection reports such as SGS/BV/CCIC. Rich export experience to ensure timely delivery. Application areas of ferrosilicon and magnesium spheroidizers: Cast iron field: used as a spheroidizer, vermicular agent and inoculant. Rare earth ferrosilicon magnesium alloy (magnesium alloy spheroidizer) has high mechanical strength and strong deoxidation and desulfurization effect. Steelmaking additive: used in the production of spheroidizers, vermicular agents and inoculants. At the same time, it is used as a steelmaking alloy additive for refining, deoxidation, and neutralization of low-melting point harmful impurities (lead, arsenic, etc.). Molten steel purification: Purify molten steel by forming new metal compounds through solid solution alloying.
