Abstract High temperature homogenization treatment and cycle heating quenching process were taken to improve the ring pattern defects in the forged bars of vacuum arc remelted TM210A steel， and then the bars were rolled. Results show that the ring pattern can be eliminated without affecting mechanical properties of the bars by high temperature homogenization treatment and rolling process.
