company news about ferromolybdenum production process

Ferromolybdenum is an alloy of iron and molybdenum, which is used as an additive in the production of steel to improve its strength and corrosion resistance. Here's a brief overview of the process for producing ferromolybdenum:

1. Roasting: The raw materials for ferromolybdenum production are molybdenum oxide (MoO3) and iron oxide (Fe2O3). These materials are mixed together and roasted in a furnace at a high temperature (around 1,200°C) to convert the molybdenum oxide to molybdenum dioxide (MoO2).

2. Reduction: The roasted mixture is then transferred to an electric furnace, where it is mixed with iron and heated to a high temperature (around 1,600°C) in the presence of a reducing agent, such as aluminum or silicon. The reducing agent reacts with the molybdenum dioxide to form molybdenum metal, which then alloys with the iron to form ferromolybdenum.

3. Refining: The resulting ferromolybdenum is then refined to remove impurities and adjust the molybdenum content to the desired level. This is typically done by adding a slag-forming material, such as lime or silica, to the molten alloy and then skimming off the impurities that rise to the surface.

4. Casting: Once the desired composition and purity are achieved, the molten ferromolybdenum is cast into ingots or other shapes for shipment and further processing.
