Overview of rare earth ferrosilicon alloy:

Rare earth ferrosilicon alloy generally contains rare earth 17%-37%, Si35%-46%, Mn5%-8%, Ca5%-8%, Ti6%, and the rest is iron. The alloy is silver gray with a melting point of 1473-1573°C.

Rare earth ferrosilicon alloy is an alloy made of ferrosilicon, rare earth, calcium, pig iron, or scrap steel in a certain proportion and melted at a high temperature. The production of rare earth ferrosilicon alloy is carried out in a submerged arc furnace, which consumes a large amount of power and can also be used for intermediate frequency Furnace production.

The role and use of rare earth ferrosilicon alloy:

A. Used for cast steel and cast iron, with strong deoxidation and desulfurization effects;

B. It is the basic material for the production of nodules, creeping agents, and inoculants;

C. Used as an additive and alloying agent in the production of steel and iron;

3. Product production
