在分析轧机工作辊径对轧机横向刚度和纵向刚度的影响的基础上,研究了在考虑带钢压下率的情况下冷连轧机的最佳工作辊径配置问题。可以看出,通过优化冷连轧机的工作辊辊经配置有利于减小和消除热轧来料的厚度和板形扰动,提高冷轧成品的厚度和板形控制精度;同时易于冷连轧机来料的咬入,提高冷轧带钢出口轧制速度;配辊方案将冷连轧机工作辊辊径按机架分成两个部分,易于现场工作辊配辊的实现。
Based on the analysis of the influence of the work roll diameter of the mill on the lateral rigidity and longitudinal rigidity of the rolling mill, the optimal work roll diameter configuration of the tandem cold rolling mill was studied considering the strip reduction rate. It can be seen that by optimizing the configuration of the work roll of the cold tandem rolling mill, it is beneficial to reduce and eliminate the thickness and shape disturbance of the hot rolled material and improve the thickness and shape control precision of the cold rolled product; Material bite, improve the export of cold-rolled strip rolling speed; roll with the program will be tandem cold mill work roll diameter by the rack is divided into two parts, easy on-site work roll with roller realization.
