Rare earth magnesium ferrosilicon

Product details

We devote our special attention to using only the rich quality raw materials followed by rigorous quality control so as to ensure that every product is delivered in strict compliance with national as well as international standards.

Ferro Silicon Magnesium Introduction


The rare earth magnesium Ferrosilicon alloy is a gray black solid. It is a good spheroidizing agent with strong deoxidation and desulfurization effect. Ferrosilicon, rare earth metal and magnesium metal are the main raw materials for producing rare earth magnesium ferrosilicon alloy. The production of rare earth magnesium ferrosilicon alloy is carried out in submerged arc furnace, which consumes a lot of electricity. It can also be produced in medium frequency furnace. In the process of cast iron, the additive added to the molten iron to make graphite precipitate in a spherical shape is called spheroidizing agent. The spheroidizing agent containing rare earth elements is called rare earth spheroidizing agent.


Ferro Silicon Magnesium Feature


  • Higher quality castings through maximum nucleation
  • Improved graphic nodularity
  • Fewer as-cast carbides in thin section castings for improved machine-ability
  • Reduced heat treatment costs
  • Precise control of rare earth levels with single alloy addition
  • Higher levels of ferrite & lower hardness for given composition and section sizes
  • Greater tolerance to slightly higher level of pearlite promoting residual elements.
  • Magnesium from dolomite can be made in the Pidgeon process with the use of Ferro silicon.

Ferro Silicon Magnesium Usage

It is mainly used in mechanical casting industry as spheroidizing agent for the production of nodular cast iron. The additive can promote graphite crystallization into spherical shape in nodular cast iron.

Ferrosilicon, rare earth ore and metallic magnesium are the main raw materials for the production of Ferro Silicon Magnesium alloy. The production of rare earth magnesium ferrosilicon alloy is carried out in a submerged arc furnace, which consumes a lot of electricity, and can also be produced in an intermediate frequency furnace.

Ferro Silicon Magnesium alloy is one of the most important inputs in the manufacturing process of spheroidal graphite iron and find usage in low carbon grades of steel due to their low carbon content.
