The main raw material for smelting ferro molybdenum is molybdenite (MoS2). Molybdenum concentrate is usually oxidized by multi-hearth furnace before smelting to obtain roasted molybdenum ore with sulfur less than 0.07%. Iron molybdenum smelting generally adopts the outside furnace process. The furnace is a cylinder placed on a sand base, lined with clay bricks, with 75% silicon ferrosilicon and a small number of aluminum particles as reducing agents.
After the charge is added to the furnace barrel, it is smelted by the upper ignition method. An initiator (saltpeter, aluminum chips or magnesium chips) is used on the surface of the material, which is a violent reaction after ignition, and then sedated, slagging, and demolition of the furnace tube. The ferro molybdenum ingot is first cooled in the sand pit, then sent to the cooling room for flushing and cooling, and finally broken and finished. The metal recovery rate is 92 ~ 99%.
What about the ferro molybdenum market
Entering mid September, the steel plant is expected to continue bidding due to the need for stock preparation during the National Day holiday.
However, the rise in raw material prices has been hindered and the price of ferro molybdenum is difficult to continue to rise, and the supply and demand game is becoming more intense.
It is not easy to buy at low prices these days and the bidding situation of steel mills is waiting to see.
Ferro Molybdenum composed of iron alloys, generally containing 50 to 60% molybdenum, used as alloy additives for steelmaking. Guida Metals produces ferromolybdenum in a wide range of specifications at an inexpensive price that makes it your best choice.
