Product Description
Ferro molybdenum ( Ferro moly ) is an exceptional alloy primarily made up of iron (Fe) and molybdenum (Mo). This top-tier alloy is crafted with precision by melting iron and molybdenum sources-often ferrosilicon and high-grade molybdenum oxide-in a furnace. This process yields an alloy that commonly exhibits a molybdenum concentration ranging from 50% to 75%. Crucially, for logistical considerations, ferro molybdenum is deemed non-hazardous for transportation.
Ferro molybdenum plays a vital role as an additive in steelmaking and cast iron production. Its integration dramatically enhances the hardenability, strength, and corrosion resistance of metal products. The robust molybdenum content allows the alloy to endure extreme temperatures, making it perfect for challenging applications in automotive, construction, petroleum, and natural gas sectors.
Physical and Chemical Properties of Ferro Molybdenum- Atomic weight of Molybdenum (Mo): 95.94. Outer electron configuration: 4d5s. Melting point: 2615°C. Boiling point: 4610°C. Density (at 20°C): 10.2g/cm³.
- Solid Solutions and Intermetallic Compounds : Molybdenum forms both α and γ solid solutions with iron, alongside two intermetallic compounds, ε (Fe7Mo6) and σ (FeMo).
- Composition : Typically, industrial-grade ferro molybdenum comprises about 60% Mo, with a melting temperature range of 1800 to 1900°C, and a density near 9.0g/cm³.
- Role in Steel : Ferro molybdenum is instrumental in boosting hardenability, thermal strength, resistance to temper embrittlement, residual magnetism, coercivity, and protection against corrosive environments, particularly against pitting. It is extensively employed in diverse steel types, including structural, spring, bearing, tool, stainless acid-resistant, heat-resistant, and magnetic steels.
- Role in Cast Iron : Notably enhancing the strength and toughness of cast iron, ferro molybdenum forms a pearlitic matrix structure in castings with medium to large sections when added in quantities of 0.25% to 1.25%. This is especially advantageous in rolls and other wear-resistant castings.

Smelting Method for Ferro Molybdenum
Typically, the production of ferro molybdenum is achieved via the highly efficient metal thermal method.
The key raw material for smelting ferro molybdenum is molybdenite (MoS2). Before smelting, molybdenum concentrate is typically subjected to oxidative roasting in a multi-hearth furnace, resulting in roasted molybdenum concentrate with a sulfur content of less than 0.07%.
The smelting process of ferro molybdenum, a hallmark of innovation, predominantly employs an external furnace method. This method utilizes a cylindrical furnace, intricately lined with clay bricks, and set upon a sand foundation. The charge, a carefully crafted composition, includes ferrosilicon with an impressive 75% silicon content and a hint of aluminum granules as a powerful reducing agent. The smelting adventure kicks off with a spectacular top ignition method: an igniter-such as saltpeter, aluminum shavings, or magnesium shavings-ignites the charge surface with fervor. Following this fiery initiation is a tranquil phase, accompanied by precision slag tapping and the strategic removal of the furnace cylinder. The resulting ferro molybdenum ingots undergo an initial cooling in a sand pit, followed by water cooling in a specialized cooling chamber, before being expertly crushed and refined. The process achieves remarkable metal recovery rates ranging between 92% to 99%. In recent advancements, oxygen molybdenum briquettes have emerged as a favored alternative in the steelmaking industry, showcasing versatility and innovation.
