Analysis of tendency of ductile fracture at corner of workpiece during grooveless rolling 无槽轧制轧件角部的韧性断裂趋势分析
Abstract : determining nip point is important for steady rolling section steel 文摘:确定型钢轧制时轧件的咬入点对实现稳定轧制有重要意义。
Theoretical direction may be provided on judging defect of rolling workpiece surface 从而为估测楔横轧成形阶梯轴类件时轧件表面是否会产生缺陷提供理论指导。
It is indicated that three - roll cross wedge rolling process has a distinct advantage in the forming quality of the center of rolled pieces 分析表明,三辊楔横轧轧制工艺在轧件心部成形质量上具有明显的优势。
Based on analyzing the intersection curve between the rolled - piece and roll , the method of determining the nip point is put forward 基于对轧件与轧辊截交线的分析,提出了在二维直角坐标系中确定轧件咬入接触点的方法。
