摘　　要：研制了新型支承辊材料,并成功制造了两支支承辊。结果表明,新型支承辊材料具有较高的淬硬性、淬透性、抗回火稳定性和强韧性,工作层内为全马氏体组织,提高了支承辊耐磨性和抗接触疲劳强度。A new type of backup roller material has been developed,and two backup rollers have been manufactured successfully.The results show that the new backup roll material has high hardening capacity,hardenability,tempering stability,strength and toughness,and the working layer is complete martensite structure,which improves the wear resistance and contact fatigue strength of the backup roll.

关 键 词：新型支承辊 淬硬性 淬透性 全马氏体
