Abstract The formation and deformation mechanism of oxygen inclusions in Al-killed wheel steel without calcium treatment were studied by industrial trials based on systematic sampling and electron microscopy analysis on inclusions morphology， size and composition. It can be found that， under the condition of no calcium treatment， massive MgO-Al2O3 inclusions and CaO-Al2O3 inclusions were formed during LF refining and there was a transformation process from MgO-Al2O3 inclusions to CaO-Al2O3 inclusions during RH refining， which leads to generate massive low-modified CaO-Al2O3 inclusions in slab.；During the process of soft bottom stirring and holding process， there can exist a dynamic equilibrium between reoxidation of molten steel by slag or air and flotation removal of inclusions in ladle； During solidification process， Al2O3 based inclusions surrounding a little MnS were formed because Al2O3 based inclusions provided the position of heterogeneous nucleation of MnS precipitation in the interface of solid and liquid during solidification， which made MnS easier precipitate on the surface of Al2O3 based oxygen inclusions. During hot rolling process， alumina inclusions of clusters were often deformed to chain-like ones， Al2O3 based inclusions surrounding a little MnS to tiny tail-like ones， and low-temperature point CaO-Al2O3 inclusions to long striped ones.

Key words： Al-killed steel wheel steel non-calcium treatment inclusion deformation
