以某厂镀锡板连退机组双机架HCM平整机为研究对象,理论分析结合有限元仿真和现场实验,对硬质薄规格镀锡板的平整轧制变形行为进行了研究,揭示了硬质薄规格镀锡板平整时轧制力偏大、实际延伸率达不到设定目标延伸率以及实物板形质量较差的原因,确定了相应的解决问题的技术思路.在此基础上,运用基于有限元仿真的辊形设计方法和软件,研制了新的中间辊端部辊形.生产应用结果表明,该中间辊端部辊形能够有效地减轻压靠、稳定实现设定的目标延伸率且实际平整轧制力降低10%～20%,而且还可以根据需要在正常平整轧制力下使实际延伸率增加0.1%～0.2%.
Taking a double-stand HCM flattening machine with tin-plate continuous-back unit of a factory as the research object, the finite element simulation and field experiments were carried out to study the flat rolling deformation behavior of the hard thin-gauge tinplate, Hard thin tinplate flat rolling force is too large, the actual elongation of less than the set target elongation and poor quality of the physical shape of the reason to determine the appropriate technical solutions to problems on the basis , A new intermediate roll end roll shape was developed by using the roll shape design method and software based on the finite element simulation.The production application results show that the roll shape of the intermediate roll end roll can effectively reduce the pressure and stabilize the set target Elongation and the actual formation of the rolling force reduced by 10% to 20%, but also according to the normal rolling in the normal elongation of the actual rate of increase of 0.1% to 0.2%.
