What Is Ferrosilicon Magnesium?

Ferrosilicon magnesium, also known as FeSiMg alloy, is a remelting alloy made up of Ferro silicon, Magnesium, rare earth, and Calcium.
As an additive, it can crystallize the graphite in cast iron into a ball shape. Its’ main elements are Si, Mg, Re, Ca, etc. The silicon magnesium alloys containing rare earth elements are divided into ordinary rare earth nodularizer and yttrium base heavy rare earth nodularizer.

Magnesium has the strongest spheroidizing ability and it is most widely used as spheroidizing agent. However, magnesium has a low boiling point, which is much lower than the temperature of molten iron. Therefore, when pure magnesium is used as a spheroidizing agent, the magnesium will be gasified at a high speed, which is not safe and economical, and will also pollute the environment. In nodular iron foundries, in order to slow down the gasification of magnesium, cast iron manufacturers generally use ferrosilicon-magnesium alloys with a mass fraction of magnesium not exceeding 10%, or rare earth ferrosilicon-magnesium alloys as spheroidizing agents.

Ferrosilicon Magnesium uses

The ferro silicon magnesium is a common additive used in the steelmaking industry.

  1. In iron steel making, it is added as the nodularizer, the vermiculizer, and the inoculant. With strong mechanical strength, it works well in deoxidation and desulfurization.
  2. It can also be used as alloy agent for refining, deoxidation, denaturation and neutralization of harmful impurities (Pb, arsenic, etc.) with a lower melting point. By solid solution alloying, the ferro silicon magnesium can help to form new metal compounds with the impurities, to purify the steel.
