1 The experience of melting sponge iron in induction furnaces infers that the best usage and melting of the sponge iron can be achieved if the particle size of the sponge iron is in close range and its metallization is 90. The density of its particle should be as high as possible. 2 Even acidic slag facilitiates the melting of sponge iron.
