摘要
涟钢1800CSP热轧平整机在生产中存在一些板形缺陷,板形质量异议在5%以上。为了提高该机组的板形控制水平,减轻工作辊"W"形不均匀磨损对板形的影响,并提高单辊过钢量,针对热轧平整机工艺特点,以工作辊和支撑辊间接触压力分布均匀化和前张力分布均匀化为目标,优化设计了新的工作辊及支撑辊辊形。理论计算和现场应用表明,优化后新辊形使辊间接触压力分布趋于均匀,平整机工作辊"W"形磨损得到缓解,单辊过钢量与板形质量均显著提高。
Product of 1800CSP hot rolling skin pass mill in Liansteel has shape defects frequently.The amount of shape unqualified exceeds 5%.In order to improve strip shape and reduce the impact of ＂W＂-like heterogeneous roll wear to strip flatness,work roll and backup roll profiles are designed via the optimization method,which aim at making the transverse distribution of pressure between rolls and transverse distribution of front tension homogeneous.The theoretical calculation and actual application shows transverse distribution of pressure between rolls become more homogeneous.With the application of optimized profiles,＂W＂-like wear of work roll is decreased,then total weight of rolled strip is increased and strip shape is improved.
