摘要
针对冷轧带卷存在心形卷缺陷的问题,分析了卷取机内套筒的受力情况,以及内套筒所用的焊接钢管的屈曲规律,得出套筒所受环向应力较大是其主要原因,通过采取较低的卷取张力、选择合适的带钢表面涂油量、对应不同的卷重选用合适壁厚的套筒等措施,可避免心形卷的产生。
For heart-shaped coil of cold rolled strip,the force situation of inner sleeve and its material compression deformation were analyzed. The main cause was the sleeve by large circumferential force. Therefore, thesmall coiling tension was applied, reasonable amount of surface coating oil was selected, and different wall thickness of sleeve was used for different coil weight. By these measures, the heart-shaped coil defect was eliminated.
