Products Description

Ferromolybdenum smelting generally adopts an out-of-furnace method. The furnace is a cylinder placed on a sand base, lined with clay bricks, and ferrosilicon containing 75% silicon and a small amount of aluminum particles are used as reducing agents.

After the furnace material is added to the furnace tube at one time, it is smelted by the upper ignition method. Use an initiator (saltpeter, aluminum scrap or magnesium scrap) on the surface of the material, and it will react violently after ignition, then sedate, release slag, and remove the furnace cylinder.

The ferromolybdenum ingots are first cooled in the sand nest, then sent to the cooling room to be flushed with water for cooling, and finally crushed and finished. The metal recovery rate is 92-99%. Molybdenum oxide briquettes have been widely used instead of ferromolybdenum in the steelmaking industry in recent years.

The product is delivered in blocks, with a block size ranging from 10 to 150mm, and the particle size below 10 10mm shall not exceed 5% of the total weight of the batch. A small amount of block size is allowed, and the maximum size in one direction is 180mm.
