Introduction
Rare earth ferrosilicon alloy is made of ferrosilicon, rare earth, calcium, pig iron or scrap steel and other ingredients by a certain proportion of high temperature melting alloy. The production of rare earth ferrosilicon alloy is carried out in the ore heat furnace, which consumes a lot of power, and can also be produced by the intermediate frequency furnace.
Purpose
1, used in cast steel cast iron, has a strong deoxidation, desulfurization effect.
2. It is the basic material for the production of spheroidizing agent, vermicularization agent and inoculant.
3, in the production of steel, iron as an additive, alloy agent.
