Abstract Changes in composition and morphology of inclusions during steelmaking and rolling process of tire cord were studied by ASPEX PSEM explorer. The results showed the content of SiO2 in inclusions in as-cast bloom increased a little compared to that in the tundish and dual-phase structure of pure SiO2 in MnO-SiO2-Al2O3 matrix were also observed in as-cast bloom. Inadequate deformation SiO2-type inclusions were observed in rolling products. Thermodynamic analysis showed that mass transfer between liquid steel and inclusions resulted in the rise of SiO2 content in inclusions from tundish to as-cast bloom and accelerated the precipitation of pure SiO2 phase in the formed inclusions. SiO2 solid phase was highly likely to precipitate out from MnO-SiO2-Al2O3 inclusions to form dual phase inclusions，compared to precipitate from CaO-SiO2-MnO-Al2O3 inclusions. During hot rolling，the homogeneous CaO-SiO2-Al2O3-MnO and MnO-SiO2-Al2O3 can easily be elongated and presented long strip shape in rolled products. Phase separation in the dual phase inclusion of MnO-SiO2-Al2O3 and SiO2 may occur for its inhomogeneous composition during rolling accounting for the distribution of non-deformable SiO2 inclusions in the wire rods and some eye-shaped and single-particle inclusions were generated.
