Abstract In order to improve the central segregation and radial distribution of solutes of the 35CrMnSi alloy constructional steel continuous casting billet with a section diameter of 300 mm, Pulsed Magneto-Osillation (PMO) technology developed by the Center for Advanced Solidification Technology was applied. With the PMO treatment in the secondary cooling zone, the distribution uniformity of C along the radial direction of the billet was improved, the range of C decreased by more than 40%, and the ranges of Cr, Mn, Si in the center of the billet decreased by 18%, 16% and 33%, respectively. The serious segregation phenomena of C, Cr, Mn and Si in the center of the billet were eliminated. The solutes distribution of 35CrMnSi alloy constructional steel billet was improved without changing the original continuous casting process. It provides a new method to improve the central segregation by improving the center quality of ø300 mm round billet.

Key words： PMO solute distribution continuous casting billet alloy constructional steel central segregation
