摘要
结合三辊轧制的优点,提出在钛合金棒材精轧机之后增加1架弧三角孔型三辊轧机和4架三辊可调切线孔型减定径机组,来减小棒材尺寸公差,同时采用有限元分析对通过该机架的变直径棒材进行模拟轧制,最终获得了尺寸公差精度完全符合要求的产品。通过模拟和现场实测结果说明在钛合金棒材精轧机后增加三辊组合孔型轧机的方法是完全可以提高钛合金棒材的尺寸公差。
Combining the advantages of three roll rolling,one frame three roll rolling with arc triangle groove and four frame three roll rolling with adjustable tangent pass were puted after finishing roll. It can reduce the bar size tolerance. And while simulated the rolling through the several variable diameter bars using finite element method. The finally dimensional accuracy meets the requirements of products. The simulation shows that the method of adding three roller combined rolling mill in the finishing mill of titanium alloy bar can improve the dimensional tolerance of the titanium alloy bar.
