Description

premelted refining slag/RuiShi brand calcium ferrite/calcium ferrite/calcium ferrite dephosphorization/calcium feerite slag/selling calcium feerite slag/melting steel additives/RuiShi brand dephosphorization 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
