铜及铝板带轧制过程中轧机不稳定因素探讨

Discussion on Rolling Mill Unstable Factors During Copper Strip Rolling Process

有色金属板带材轧制过程中,会出现各式各样轧制过程不稳定现象,是生产高精度带材的大敌之一。目前,对该问题的研究主要集中在钢铁行业的带钢轧机上。由于有色金属板带材和钢铁的性能有所区别,轧机的要求也有所不同。具体到某一钢铁厂来讲,如连铸连轧的厂家,虽然年产几十万吨,但只有一种金属或合金成分,品种较单一;而一个铜板带车间不要说有数百种产品规格,仅合金成分就不下数十种。有色金属轧制时,轧机的速度虽然没有钢铁轧机高,轧机规格没有钢铁大,但轧机调试困难程度毫不亚于钢铁轧机。本文仅从工艺的角度对轧机轧制过程不稳定现象进行分析,与各位同仁共同商榷。

Although the research works on rolling mill unstability are mainly concentrated on steel strip rolling mills,the various unstable phenomena may occur on the nonferrous metals rolling mills,which are formidable enemies for producing high - accuracy stdps.In this paper the author analyzes the unstable phenomena from the point of view of the rolling process and introduces the means and ways to eliminate or minimize them.
