. Scale defects are one of critical problems at hot steel rolling process .. Scale is formed during heating and cooling of rolling process ... Generally, conditions of reheating furnace and cooling rate at rolling process are controlled to reduce scale defects ....In this study, rolling pass schedule is changed to improve scale defects which are detected mainly on the center of flange surface as band or line shape .
