The composition and microstructure of vanadium-titanium sinters with different MgO contents were determined by means of polarization microscope.The result shows that,as MgO content increased,the microstructure transferred from melting corrosion to granular structure.Meanwhile,he content of metal phase increased and the content of binder phase decreased.The tumbler strength of sinter decreased,and RDI of sinter improved.The content of MgO in sinter raw material of Chengde Iron&Steel Corporation is proposed at around 2.0%.
