Abstract
The influence of different magnesium content on the inclusions in steel was studied under the condition of the same molten steel at 1873 K. The results show that, after the magnesium treatment, the tiny MgO•Al2O3 inclusions could become the nucleus of MnS in solidification of liquid steel, which weakens the large number of MnS precipitates in grain boundaries. The change of the oxide core in the composite sulfides with the increase of magnesium content is: Al2O3 MgO•Al2O3 MgO•Al2O3+MgO MgO+MgS.This evolution mechanism can provide certain reference for the application of magnesium treatment in production practice.
