以宝钢2030 5机架冷连轧机为研究对象，经过现场试验与理论研究，在分析了影响冷连轧机成品带钢表面粗糙度的主要因素的基础上，提出了一套冷连轧机成品板面粗糙度预报模型，给出了针对冷连轧机的成品板面粗糙度控制方案，并将其应用到现场成品板面粗糙度控制，命中率达到80%以上。
Taking 2030 fivestand cold tandem mills at Baosteel as the object and through field experiment and theoretical research, a set of prediction models and the control scheme for surface roughness of cold rolled strip were put forward based on the analysis of the main factors of surface roughness. By use of such control technique, the hit rate of surface roughness has reached over 80%.
