Composition evolution and deformation of different non-metallic inclusions in a bearing steel during hot rolling

The composition evolution and deformation of different non-metallic inclusions in a bearing steel during hot rolling were investigated by the automatic detection and the improved non-aqueous electrolysis method. Manganese sulfide, MnS–TiN, and liquid CaO–Al 2 O 3 inclusions were elongated while TiN...

Summary:The composition evolution and deformation of different non-metallic inclusions in a bearing steel during hot rolling were investigated by the automatic detection and the improved non-aqueous electrolysis method. Manganese sulfide, MnS–TiN, and liquid CaO–Al 2 O 3 inclusions were elongated while TiN and MgO⋅Al 2 O 3 were fractured during hot rolling. The CaS–MnS phase in the MgO–Al 2 O 3 –CaS–MnS inclusion was separated from the inclusion, leading to the formation of CaS–MnS type clusters. Meanwhile, the CaS and MnS contents in oxide-containing inclusions decreased while the MgO and Al 2 O 3 contents increased after hot rolling. The deformability of different inclusions in the bearing steel was quantitatively compared and discussed.
