摘    要：通过对分段辊测张式板形仪板形检测原理的分析发现,分段辊区域宽度对板形检测精度影响较大。将板形曲线分为简单曲线和复杂曲线两种情况,以典型的实际板形曲线为例,分析不同曲线下分段辊区域宽度对不同宽度轧材的板形检测精度的影响,分析时考虑了轧材板形曲线的关键特性,如曲线的单调性、曲线极值所在区域的凹凸性以及曲线陡峭或平缓程度等特性,最后根据分析结果得到不同情况下的板形检测误差及相关重要结论。

Abstract: Through analysis of shape measuring principle of tension measuring type shapemeter with segmented rolls,it is found that effect of width of segmented roller on shape detection precision is large.Shape curve can be divided into simple curve and complicated curve.Taking typical and practical shape curves as an example,effects of segmented roll width on shape detection precisions of strip with different widths were analyzed considering key character of strip′s shape curve,such as,monotonicity of curve,concavity and convexity of area where the extreme point is in,and steep or smooth degree of curve etc.Based on analysis results,shape detection errors and relative conclusions are obtained.
