Abstract

PURPOSE: To inspect a black back extremely thin round steel highly efficient and highly accurate, by removing hampering primary factors to magnetic flaw detection by using a bending corrector.
CONSTITUTION: A black bark extremely thin round steel RL to be inspected is fed to a two-roll type bending corrector 3 to correct bending to remove scale to reform a warp and to improve roundness. Flaws on the surface of the round steel discharged from the bending corrector 3 are detected by a magnetic flaw detector 4.
