中板四辊轧机薄规格产品轧制稳定性的探讨

THE RESEARCH ON STABILITY OF ROLLINGTHIN PRODUCTS ON 4HIGH PLATE MILL

提出了在中板四辊轧机上轧制厚度为８ｍｍ以下的薄规格钢板时的稳定轧制条件，综合辊凸度Δ≤－０．１５ｍｍ，上下轧辊的轧制速度相同，上下主电机的负荷相同或相近。同时介绍了为保证稳定轧制需采用的两种换制度，以保证辊耗降低。

This paper puts forward the stable rolling conditions when rolling thin plate below 8mm on 4high plate mill: composite roll convexity Δ≤-05mm, the rolling speeds of upper and lower roll are same, the loads of upper and lower main motor are same or nearAt the same time, two kinds of rollchanging regulations for ensuring stable rolling are intorduced in order to ensure low roll consumption
