| 摘 要： | 针对带钢开卷工序存在的松卷与层间滑移缺陷，考虑开卷机组设备与工艺的特点，通过理论研究与现场试验，建立了钢卷开卷过程中内部应力的分布模型，实现了对开卷过程钢卷内部应力分布的预报。在分析松卷与层间滑移缺陷产生机理的基础上，采用开卷层滑因子来定量描述松卷与层间滑移缺陷程度，结合钢卷开卷过程中的内部应力分布模型，开发了钢卷开卷过程中开卷张力的综合优化设定技术，达到了综合防控开卷过程中钢卷松卷与层间滑移缺陷的目的。

| Abstract: | With reference to problems of coil relaxation and interlayer slip in steel roll uncoiling processes, this paper fully considered mechanical and technological characteristics of uncoiling unit by a large number of theoretical researches and field tests, established a set of internal stress distribution models of steel roll uncoiling, and achieved prediction of internal stress distribution in uncoiling processes. Based on generation mechanism analyses of coil relaxation and interlayer slip, a new concept of “uncoiling layer sliding factor” was proposed to describe the degree of coil relaxation and interlayer slip quantitatively. With combination of internal stress distribution models, a set of uncoiling tension comprehensive optimization technology was developed to prevent and control the defects of coil relaxation and interlayer slip. |
