摘要
介绍了国外万能轧制技术的原理、设备配量、孔型设计及对重轨断面尺寸精度的影响；分析了传统轨梁轧机的固有问题及造成重轨几何尺寸超差的根本原因，提出了万能轧机轧制重轨是当代提高重轨轧制精度的有效方法。作者针对攀钢的实际情况提出了建议。
The principle of world-wide universal rolling technology,plant layout,pass design and their effects on the dimensional accuracy of heavy rail section are reviewed.An investigation is con-ducted on the inherent problems of traditional rail and beam mills and the primary causes of rail di-mensional variation,It is proposed that the current use of universal rolling technology is a method to improve heavy rail rolling tolerance. The suggestions are put forward for Panzhihua I.&S. Co.to adopt this technology.
