Abstract Scope |
The evolution behaviors of non-metallic inclusions in 55SiCr spring steel were carried out in three melts treated by titanium and calcium in present study. The composition and morphologies of inclusions were determined by FE-SEM&EDS. The results show that less titanium content more easily modifies the inclusions into the liquid phase ones in Si-Mn-Al deoxidized melt. And more calcium content in steel not only transform more solid inclusion to liquid inclusion for cleanliness, but also to avoid that accumulation of titanium oxides in inclusions. The thermodynamic calculations of inclusion were performed in Si-Mn-Al-Ti-Ca-O steel system at high temperature and during solidification process by using Factsage 7.2, the thermodynamic calculations consistent with the experimental results, which can predict the formation of the inclusions in Ti-bearing Si-Mn-Al deoxidized steel. |
