Fused Calcium ferrite is a mixture of low melting point after premelting, put it into melting furnace and form liquid state immediately and achieve the purpose of slagging at the beginning of smelting.
Characteristics: Slag forming fast, strengthen the dephosphorization,smelting shortened, replac smelting fluorite, favorable environmental protection, reduce oxygen consumption, improve the yield of metal.
