| 摘 要： | 针对唐钢冷轧厂生产的低碳钢板所存在的断裂、皱折等深冲性能问题,本文讨论了Δr值对深冲性能的影响,论述了Δr值作为钢板深冲性能指标的重要意义。通过实验,得出Δr值随着变形量的增大而不断减小的结论,并从变形不均匀角度进行了机理分析。

| Abstract: | Low-carbon steel of Tanggang cold rolling factory is not qualified for deep-drawing because of its breakness and wrinkling.The paper discusses the importance of Δr as one of deep-drawing parameters.By experiment,it draws the conclusion that Δr goes smaller when reduction become bigger,at the same time,the reason for the conclusion is analyzed from perspective of uneven deformation. |
