The results show that large Al_2O_3 inclusions concentrating on the edge of CSP sheet bar cause the cracking during rolling.

The results show that the surface inclusions of cold-rolled IF steel product mainly consisted of the cluster and lump Al_2O_3 inclusions above 100 μm because of re-oxidation in tundish,and they were predominantly located in slab surface layer and at one forth of slab thickness.

Research on inclusions in billet continuous casting of steel ML08Al;

New technology for control and removal of inclusions in tundish;

Formation and Control of Inclusions in Si-Mn Cast Steel with High Carbon Content;

The fault between the impurities containing Zr and matrix is not formed during the rolling process but are depend on the microstructure after rolling.

Research on Inclusion Controlling Technology of Low Carbon Al-killed Steel;

Influence of Electromagnetic Brake in the Continuous Casting on the Non-metallic Inclusion of the Slab;

Analysis and Control of Macro Inclusion in Structural Steel Melting by EAF-LF-CC Process;

There were mainly two types of non-metallic inclusions in the steels,which were the MnS-MnO typed inclusions and TiN-VN typed inclusions.

In combination with the practice and application, the microstructure and non-metallic inclusions at different levels in 16MnDR,15CrMoR and 15MnNbR pressure vessel plate was analysied,which provide the basis for an improvement on quality of the higher pressure vessel plate.

The microstructure and non-metallic inclusions in the medium thickness CC slab of 135 mm were observed and analyzed by using optical microscope and scanning electron microscopy.
