What is rare earth ferrosilicon?

Rare earth ferrosilicate alloy is made of ferrosilicate, rare earth, calcium, pig iron or scrap steel according to a certain proportion of batching through high temperature melting of the alloy, rare earth ferrosilicate alloy production is carried out in the furnace, power consumption is large, can also be used in the production of medium frequency furnace.Rare earth ferrosilicate alloy is very effective as denaturant in steel.

Rare earth ferro-silicon alloys generally contain 17%-37% rare earth, Si35%-46%, Mn5%-8%, Ca5%-8%, Ti6%, and the rest is iron.The alloy is silver gray, melting point is 1473-1573℃.Rare earth ferrosilicon is massive, metallic luster, hard and brittle, easy to crush.Rare earth ferrosilicon alloys are silvery gray.The rare earth ferrosilicon magnesium alloy gleamed blue in a silver-gray matrix.
