Dissolution kinetics of magnesitic-dolomite and magnesite-chrome refractories in secondary steelmaking slags was studied by means of the rotating cylinder method under forced convection. Materials investigated include four magnesitic-dolomite samples(MgO content 40% to 93%)and two magnesite-chrome samples (co-clinkered and semi-rebonded).Synthetic slags simulative of VOD and AOD slags with varying basicity (0.6-2.68) are used.The experiments are carried out in Ar atmosphere at different temperatures (1 600 ℃-1 750 ℃) and revolution speeds (200 r·min-1to 500 r·min-1).The microstructure of specimens (before and after slag tests) are studied by optical microscopy, SEM and EPMA. Based on our experimental results the mechanism and kinetics of the dissolution process are discussed.
