Effects of Graphite, SiO 2 , and Fe 2 O 3 on the Crushing ...

2017-6-23 · The softening and melting temperatures of slag were adjusted by changing the slag basicity and FeO content. A proper amount of Fe 2 O 3 or SiO 2 addition increased the crushing strength of DRI due to the softening of slag. Excessive Fe 2 O 3 or SiO 2 resulted in the melting of slag, which decreases crushing strength.
