The source and negative effects of macro-inclusions in Ti-IF steel were studied by sliming extraction, ultrasonic detection, depth corrosion and SEM/EDS. High SiO2 content inclusions, and Al2O3 and MgO· CaO inclusions were observed after sliming. Ultrasonic results showed that defects in the surfboard with sizes 0.5 mm-3mm were mainly distributed in the inner arc and outer arc sides close to 1/8 of the slab’s surface. The number of defects in the inner arc side was 1.5 to 2 times of that in the outer arc side. Defects in the surfboard and cold-rolled plant were formed due to inclusions which were similar to that observed in the sliming sample.
