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 high temperature. The production of rare earth ferrosilicon alloy is carried out in submerged arc furnace, which consumes a lot of power and can also use intermediate frequency Furnace production.

 

 

Features:     

 

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.

 

 

The role and use of rare earth ferrosilicon alloy:

 

 

1. For cast steel and cast iron, it has strong deoxidation and desulfurization effects;

 

2. It is the basic material for the production of nodularizing agent, creeping agent and inoculant;

 

3. Used as additives and alloying agents in the production of steel and iron;
