冷轧带钢卷取工艺优化技术研究

Research on coiling process optimization of cold rolled strip

针对酸轧机组卷取时出现钢卷松卷的问题,考虑到酸轧机组的设备和工艺特点,研究通过卷紧紧密函数、层间滑移和半径均匀度确定钢卷卷紧综合评价函数,对钢卷进行受力分析,提出卷取松卷的控制目标函数。在此基础上研究卷取张力对卷取质量的影响,进一步建立了卷取张力优化模型优化出最佳张力值。将此研究结果应用于现场生产可以预报出最佳卷取张力值,加强了现场对于钢卷内部应力场的了解,也为卷取质量的综合控制提供了参考,为企业经济效益的提高奠定了基础。

In view of the problem of coil looseness during coiling in acid rolling mill,considering the equipment and process characteristics of acid rolling mill,the comprehensive evaluation function of coil tightness is determined by coil tightness function,interlayer slip and radius uniformity,and then the force analysis of coil is carried out,so as to put forward the control objective function of coil looseness.On this basis,the influence of coiling tension on coiling quality is studied,and the coiling tension optimization model is further established to optimize the optimal tension value.The application of the research results to the field production can predict the best coiling tension value,strengthen the understanding of the internal stress field of the coil,and provide a reference to the comprehensive control of coiling quality,it lays a foundation for the improvement of the economic benefits of the enterprise.
