Abstract
The solubilities of MnS in MnO-SiO2-TiO2 melts have been investigated to clarify the mechanism of the formation of inclusions in steel durin g solidification by employing a chemical equilibration technique. A Mn S pellet was equilibrated with MnO-SiO2 and MnO-SiO2-TiO2 melts betwee n 1528 and 1723K. The solubility of MnS in MnO-SiO2 melts increases wi th increasing the ratio MnO/SiO2 and temperature. The influence of rep lacement of SiO2 by TiO2 on the MnS solubility of the MnO.SiO2-MnO.TiO 2 system has also been investigated at 1623K. The solubility of MnS in creases with increasing TiO2 content. Furthermore, the precipitation m echanism of oxysulfide inclusions during solidification of steel is di scussed.
