It was found that along with UFC temperature drop the diameter of spheroidal pearlites and interval of lamellar pearlites both decrease if the UFC rate is higher than 100 ℃/sec after high-temperature final rolling to cool the workpiece to a certain degree then it is slowly cooled to ambient temperature.
研究发现:高温终轧后以大于100℃/s的冷却速度超快速冷却到一定温度后缓冷到室温,随着超快冷段终冷温度降低,珠光体球团直径和片层间距减小;终冷温度过高只能使晶界碳化物厚度减薄但不能抑制其呈网状析出,降低终冷温度到715℃以下就可以得到抑制了网状碳化物析出的细片层珠光体型组织;随着终冷温度继续降低显微硬度增加并有退化珠光体产生,其显微硬度可达到426 HV。
