以某厂连退机组R2级高粗糙度表面镀锡基板产品开发任务为依托,通过在试验生产中带钢整体取样和离线测量表面三维形貌,以工业试验方法研究揭示了双机架平整轧制过程中带钢表面粗糙度的遗传与变化规律,运用逐步回归方法针对大量实测数据建立了双机架平整轧制过程带钢表面粗糙度遗传与变化的预测模型,并根据试验掌握的带钢表面粗糙度的变化规律和拟合获得的带钢表面粗糙度预测模型,研究建立了R2级表面镀锡基板的连退平整轧制过程粗糙度控制的工艺策略、设定模型和工艺参数,形成一套R2级表面镀锡基板粗糙度控制技术。将该套技术应用于实际生产中,在国内首次成功开发出R2级表面镀锡板,并且使R级表面镀锡基板粗糙度控制精度显著提高,基本消除了镀锡辊涂后的表面印刷图案的色差和鲜映度缺陷,创造了巨大的经济和社会效益。
Relying on the task of product development of R2-level high-roughness surface tin-plated board of a plant with continuous descending unit, the three-dimensional appearance of the strip was measured by the whole sampling and off-line in the trial production. The industrial test method revealed that the double- The rule of inheritance and variation of the surface roughness of the strip during the manufacturing process was established. By using the stepwise regression method, the prediction model of the heredity and variation of the surface roughness of the strip during the double-stand flattening rolling was established according to a large number of measured data. Surface roughness and surface roughness of the strip obtained by the fitting prediction model of the surface roughness of R2-level surface tin-plated substrate Roughing control process strategy, set the model and process parameters to form A set of R2 level surface roughness of the substrate control technology. The set of techniques used in actual production, for the first time in the country successfully developed R2-class surface tin plate, and R-class surface roughness of the substrate control accuracy significantly increased, basically eliminating the tin-coated roller surface after the printing pattern The color difference and the freshness defect, has created tremendous economic and social benefits.
