agent
premelted steel making slagging agent(calcium
feerite)can accelerate the dissolution of lime ,so it doesn't need
to use fluorite to promote melting ,to achieve fluoride-free steel
making ,reduce the furnace lining erosion ,and decrease the
environmental pollution .because of good effect of slag melting
,smelting stablity and reduce molten steel splash ,so it can
improve the yield rate of molten steel about 1%.shorten smelting
period ,slag melting quickly ,high performance dephosphorization
rate ,to achieve smelting time shortened
