以某厂连退机组R2级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,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,其中满足粗糙度精度窗口[0.37μm,0.47μm]的合格率达到65.33%,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。
Based on the task of R & D of R2-level surface tinplate substrate of a plant with continuous descending unit, the three-dimensional morphology of the strip was sampled and measured off-line in the trial production, and the industrial test method was used to study the strip rolling process The genetic and variation regularity of the surface roughness of the strip was studied. The stepwise regression method was used to establish a predictive model of the genetic variation of the surface roughness of the strip in the process of double-stand flattening and rolling according to the large amount of measured data. And the prediction model of the surface roughness of the strip obtained by the fitting was established. The technological strategy of the Roughness Control of R-level tin-plated substrate was established. The model and process parameters were set to form a set of R2 Rough surface tin plating substrate control technology. The set of techniques used in the actual production, the first successful development of the domestic R2-class surface tin plate, and R-class surface roughness of tin substrate control accuracy significantly improved, which meet the roughness accuracy window [0.37μm, 0.47μm] The pass rate of 65.33%, basically eliminating the surface of the tin-coated roller printing pattern of color and shade defects.
