Analysis of Inclusion Microstructure in Material Engineering of Steel
The sample of oxide inclusion was obtained in the different stage of steelmaking for the 65 steel. The microstructure was observed by using scanning electron microscopy (SEM) to analyze the composition and type of inclusions. It was shown that the microscopic inclusions in the high carbon steel were mainly massive and cluster Al2O3, spherical and slope silicate inclusion, calcium-aluminates inclusions and sulphide complex inclusions. The measures including raw material requirement, improving of the converter, LF refining and continuous casting operations were put forward to decrease inclusion.
