摘　　要：通过理论计算对中板工具钢轧辊成分进行设计,分别检测球化退火+淬火回火及铸态直接淬火回火试样的组织及性能,结果显示球化退火对中板工具钢轧辊热处理后性能不构成直接影响;使用数据表明中板工具钢轧辊耐磨性是普通高镍铬轧辊的2倍以上,并且其辊面保持能力优于常规高铬铁及高铬钢轧辊。The composition of medium plate tool steel roll has been designed by theoretical calculation.Microstructure and properties of samples with different heat treatment process of spheroidizing annealing+quenching and tempering and as-cast direct quenching and tempering have been tested.The results show that spheroidizing annealing has no direct effect on the properties of the middle plate tool steel roll after heat treatment.The application data show that the wear resistance of medium plate tool steel roll is more than 2 times that of ordinary high nickel chromium steel roll,and its surface retention ability is better than that of conventional high chromium iron and high chromium steel roll.
