effect of strain accumulated
度地提高变形抗力模型精度，满足制定轧制规程的需要。 中国对变形累积效应的研究始于20世纪80年代，由冶金部钢铁研究总院进行研究。这一现象的研究对人们理解和认识变形抗力与金属显微组织的内在联系，建立高精度的轧制压力计算数学模型，实现轧钢过程计算机控制提供了有力的支持。b ianxing Ieiji xiaoling变形累积效应(effeet of strain aeeumulat-ed)热塑性变形过程中，下一道次的变形抗力因上道次加工硬化的积累而增大的现象。钢在连续、多道次变形过程中，随着变形温度的降低和变形节奏的加快，前一道次变形后的奥氏体在道次间隔时间之内没有来得及发生或只部分发生再结晶软化，奥氏体以加工硬化或部分加工硬化状态进入下一个道次的变形过程，造成了后续道次的实测变形抗力将比按照传统的。一f(T，。，幻变形抗力模型的计算数值明显增大。 变形累积效应的发现与研究是随着微合金钢的控制轧制工艺研究，逐渐被人们重视与认识的在变形与变形抗力之间的一种新规律。随着变形温度降低、变形程度增大、变形速度增高和道次间隔时间缩短，变形累积效应越发变得显著。其中变形温度影响最大，道次间隔时间影响次之，变形程度影响再次，变形速度影响最小。例如在宽带钢热连轧机上采用控制轧制工艺生产含有Nb、V、Ti一类的微合金钢时，在其精轧机组的后部几个道次中就明显地存在着变形累积效应，使其实测道次变形抗力比传统变形抗力模型计算的数值高出近20%，严重地影响了带钢的尺寸精度，增加了制定轧制规程的难度。 变形累积效应的大小用残余应变系数又来表征: 入~且/(ai一1+风一，)式中凡为第i道次的残余应变系数，久一1为第i一1道次的轧制表道次压下量，召，与召一1分别为第i道次前和第i一1道次前全部道次累积的残余变形量。将传统变形抗力模型中的变形程度项，用该轧制道次的变形程度值与前面各道次所累积下来的残余变形程度值之和，作为有效变形程度的计算值代入计算，就可以大幅
