Pulsed magneto‐oscillation (PMO) has a high homogenization effect on continuous castings, but the heritability of it on hot‐rolled wire rods has not been studied. Recently, the effect of pulsed magneto‐oscillation on SCM435 cold heading steel billet and its hot‐rolled wire rod were investigated. A 180 mm × 180 mm ten‐strand continuous casting machine was used, with the first strand treated by pulsed magneto‐oscillation, and billets hot‐rolled to Φ6.5 mm wire rods. The results showed that compared with the billet without pulsed magneto‐oscillation treatment, the proportion of central equiaxed grain zone of pulsed magneto‐oscillation treated billet increased from 26.5% to 37.4%, and the secondary dendritic arm spacing of columnar was reduced. Futhermore, the segregation index ranges of Cr and Mn decreased by 47.1% and 33.3%, respectively. For the hot rolled wire rods, the solutes homogeneity and the mechanical properties of the rods produced by pulsed magneto‐oscillation treated billet were improved. And its banded structure was significantly refined, where the maximum band width was reduced from 35.4 μm to 12.3 μm. This study showed that the properties of wire rod could be significantly improved by improving the homogeneity of the casting billet by pulsed magneto‐oscillation, and a good histogenetic effect was obtained.
