company news about Ferro molybdenum in metallurgy

Ferro molybdenum is an alloy of iron and molybdenum, typically containing between 60% and 75% molybdenum, depending on the intended application. Here are the general steps involved in the metallurgy of ferro molybdenum:

1. Molybdenum extraction: The molybdenum is typically obtained from molybdenum-containing ores, such as molybdenite, through a variety of extraction methods, including roasting, leaching, and precipitation.

2. Smelting: The extracted molybdenum is then mixed with iron in the form of iron oxide or pig iron and melted in a furnace. The temperature is raised to between 1400°C and 1500°C to ensure complete melting.

3. Reduction: After melting, the molybdenum and iron mixture is reduced with a carbon source, such as coke or charcoal. This process removes any remaining oxygen and converts the molybdenum to a metallic form.

4. Refining: The molten metal is then refined to remove impurities, including slag, sulfur, and other elements. Refining is typically done using an oxygen injection process, which removes impurities while also reducing the carbon content of the mixture.

5. Alloying: Once the refining process is complete, other alloying elements, such as silicon, aluminum, or titanium, may be added to the molten metal to adjust the final composition and properties of the ferro molybdenum alloy.

6. Solidification: The molten metal is then cast into ingots or other shapes and allowed to cool and solidify. The resulting product is then ready for use in various applications.
