The calculation results by this model shows that the segregation degree of solute elements is suppressed greatly due to the precipitation of Ti-O inclusions during solidification. The inclusions can be uniformly dispersed in steel by controlling due oxygen content. The number of oxides increases and their size reduces with the increasing cooling rate. The radius of the oxides only reach 0.58μm and their number and size are uniformly dispersed in steel and help to improve steel properties by controlling the condition of CSP.
