軋輥快速拆裝式三輥定徑機孔型錯位的控制

Control of Displacement of Roll Groove Occurring during Quick Roll Change-over Process of Three-roll Sizing Mill

摘要: 了解決軋輥快速拆裝式三輥定徑機孔型錯位問題，通過分析該類定徑機軋輥機架的結構特點及孔型錯位產生的原因，提出了防止孔型錯位的方法及措施。分析認為：通過控制軋輥各部件的公差，使軋輥機架間隙配合時的間隙值在規(guī)定范圍內，并盡可能地減小孔型中心位置偏差，可較好地控制孔型錯位。

Abstract: To solve the roll groove displacement problem as occurring during quick roll change-over process of the three-roll sizing mill，based on analysis of roll stand frame structure characteristics and causes for roll groove displacement of such type of sizing mill，relevant preventative methods and measures are put forward. Specifically speaking， the groove displacement problem could be properly prevented by means of controlling the tolerances of each individual component of the roll to ensure that the clearance value falls within the specified range during clearance fitting between the roll stands，and minimizing deviation of the groove center location.
