根据冷连轧机组板形控制系统对热轧来料断面形状的检测要求,按照准确可靠、经济、简约的原则,与断面仪制造厂家共同设计了同时具有平直度检测功能的新型带钢断面形状检测仪,并开发了带钢断面形状曲线拟合处理以及断面特征参数识别计算方法。利用实测的带钢平直度信息对检测的断面形状数据进行厚度修正。实际应用结果表明,利用该带钢断面形状检测仪可以获取高精度的带钢断面形状参数,能够为冷轧机板形控制系统提供实时、准确、可靠的带钢横断面形状信息。
According to the inspection requirements of cross-section shape of cold-rolled incoming material according to the strip shape control system of cold tandem rolling mill, a new type of strip section with straightness detection function was designed in accordance with the principle of accurate, reliable, economical and simple. Shape detector, and the strip shape curve fitting process has been developed as well as the section feature parameter identification calculation method. The thickness of the detected section shape data is corrected by using the measured strip flatness information. The practical application results show that the strip profile detector can obtain high-precision strip profile parameters and provide the real-time, accurate and reliable strip shape information for the cold plate mill control system.
