| Abstract: | The new material for backup roll of hot continuous finishing rolling mill has been researched. It has been performed tests to measure OCT curves, heating temperature when quenching and tempering for the material and inspected various properties of the steel grade. The results show that the metallographic structure of （ martensite ＋ low-er bainite） matrix and （ M7 C3 ＋ MC） carbide are obtained by strengthening cooling process of quenching heat treatment to improve abrasion resistance and contact fatigue strength of backup roll and make twice rolling period for backup roll. |
