Study on the corrosion mechanism between MgO-CaO refractories and refining slag

摘要：

The refining AOD and VOD slag corrosion and penetration resistance of Magnesia-Calcia materials with different CaO from 22wt％-53 wt％ were investigated by using static crucible technique along with visual observation, SEM and XRD measurements. The results showed that the resistance ability to corrosion and penetration of these materials decreased with the increase of CaO content in specimens. This could be due to the formation of C3S and C2S during the reaction between the specimen and high CaO content slag. The reaction between the molten slag and material also created a dense surface layer, which would restrain the further penetration by the slag. It was found that the depth of the layer penetrated either by AOD or VOD slag decreased with the increasing CaO content.
