Precipitation and growth of the MnS inclusions during solidification were well predicted by the improved Clyne–Kurz and Ohnaka solute element micro-segregation models by comparison of experimental and calculated results. At the cooling rate of R c = 1.26 K s −1, the solidification fraction values for MnS precipitation in the two models were 0.929 and 0.931, respectively. A non-linear fitting curve equation for describing the relationship between cooling rate of molten steel v and average inclusion diameter d was acquired by experiments: d = 10.726 v −0.438. The MnS inclusion growth was estimated according to the model calculation results. Coupled with thermodynamic calculation of MnS precipitation, two solute element micro-segregation models, Clyne–Kurz model and Ohnaka model, were introduced and improved by taking the micro-segregations of silicon, oxygen, and other solute elements into account during the steel solidification. Effects of cooling method and cooling rate on the morphologies, size distributions, number densities, and average diameters of MnS inclusions in steels were systematically revealed. Yttrium is the first element in the fourth period d-block thus there is one electron in that energy level. Moving across, simply count how many elements fall in each block. For example, there are 2 elements in the s-block, and 10 elements in the d-block. Precipitation and growth behaviors of MnS inclusions during the solidification of non-quenched and tempered steel have been experimentally and thermodynamically investigated. The number of elements in each block is the same as in the energy level it corresponds.
