《Comparison between the surface defects caused by Al_2O_3 and TiN inclusions in interstitial-free steel auto sheets》
Note:Alssoluble aluminium in the steel;T.Ototal oxygen in the steel.
The following process was adopted to produce IF steel at a certain plant:bottom-blown converter→ladle slag modification treatment→250-t Ruhrstahl–Heraeus(RH)refining→continuous casting(1347 mm×240 mm).The converter terminal carbon content is required to be controlled at0.02wt%–0.04wt%.Before the start of RH refining,the ladle slag was modified.About 20 min after the start of the decarburization in RH vacuum degassing,the carbon content reduced to 15×10–6.After decarburization,Al was used as a deoxidizer,and Ti was added to the liquid steel after deoxidization for 3 min.After RH refining,the steel ladle was left to stand for about 40 min before casting.The composition of the IF steel used in this study is given in Table 1.
