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. get price
