It is used as flux to reduce the melting point of difficult-melted substance,accelerate the flow of slags to separate the slag and metal thoroughly in steel making.It has the characteristic of desulfurization,dephophorization,increase metal’s forgeablity and tensile strength.Thus,it is widely used in steel making,nonferrous metal metallurgy,ferroalloy metallurgy,chemical and iron industry.
