Identification and Detection of the Nature of Non-Metallic Inclusions in Continuously Cast Billets From Steel 26khgmf

The article presents data on the identification of inclusions in metal samples of continuously cast blanks. The counting and identification of inclusions was carried out using the automatic particle analyzer EDAX Particle/Phase Analysis Software. The study established the predominant type of non-metallic inclusions. It is shown that a large proportion of inclusions are endogenous and have a steelmaking nature of origin. It is shown that inclusions are unevenly distributed over the section of the cast workpiece, and the axial volumes of the workpiece have the maximum contamination. At the same time, the distribution of oxide and oxysulfide inclusions is opposite, which is associated with the course of liquation processes during solidification.
