摘要
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 product development tasks of R2 grade TMBP(tin mill black plate) in a CAPL line,the genetic and change laws of surface roughness in two-stand temper mill rolling were revealed by ways of industrial test methods through whole sampling of strip in trial production and off-line measurement of three-dimensional topography on surface.The prediction model of genetic and change laws were established by the use of stepwise regression method based on a large number of measured data.According to the variation of strip surface roughness obtained from the experiment and the prediction model,the process strategy,set models and process parameters of roughness control were set up,furthermore a set of roughness control technology of R2 grade TMBP were obtained.Applying the technology to actual production,the R2 grade TMBP was successfully developed firstly in China.The roughness control accuracy of R grade TMBP was significantly increased.Color difference after roll spreading was effectively removed.Enormous economic and social benefits were created.
