Abstract

JFE Steel has introduced an ultrasonic on-line detection system for nonmetallic inclusions in as-hot-rolled coil to be processed as tin mill black plate (TMBP). TMBP is used for draw and redraw (DRD)-can making, and requires high internal quality. It has been installed at No. 6 pickling line in East Japan Works (Chiba District). The detection result is rapidly fed back to the steelmaking process to improve steel cleanliness. As a result, TMBP coils have been kept in high internal cleanliness and defects found at users’ DRD-can making processes have dramatically decreased.
