冷轧过程中带钢楔形与跑偏关系

分享到:
  东莞市广毅荣冷拉钢厂;精密带钢在热处理生产的过程中,往往需要停下设备来对带钢的弯曲变形进行人工拉线检测,通过ADC定时采集位移传感器产生的数据,并由MCU处理、记录,可以实现对带钢弯曲变形的在线自动检测,通过试验验证该在线检测系统可以有效地提高检测精度和带钢生产效率,并实时建立起带钢弯曲变形数据库。
  Precision strip steel production in the heat treatment process often need to stop bending deformation of the strip pull test. The data which acquired by ADC timing collected by the displacement sensor and generated by the MCU processing and recording, can achieve the line automatic detection of strip bending deformation, verifying by experiment that the system can effectively improve the detection accuracy and strip production efficiency, and establish real-time database of bending strip.
  针对国内某厂冷连轧高强钢生产过程中带钢频繁跑偏问题,对原料楔形及带钢跑偏进行了模拟分析,根据体积不变原则及楔形率变化研究了带钢在机架内跑偏的静态模型和动态模型。结果显示,轧制过程中带钢原料楔形与其在机架内的跑偏呈二次积分关系,不能简单通过楔形正负抵消来消除轧制过程跑偏。
  To the problem of high-strength strip running-off frequently during cold continuous rolling, the relation ship between material wedge and strip running-off were analyzed. Both static and dynamic models of strip running off were studied based on wedge rate changing and principle of constant volume. The results show that there is 2-order integration relationship between material wedge and strip running-off during cold rolling. The running-off can not be eliminated by wedge positive-negative offset.
