张力变化直接影响到带钢轧制厚度的变化。控制张力变化是平整过程中一个非常重要的环节,在张力控制系统中,入口S辊的控制又是重点和难点,本文就入口S辊在张力控制系统中的作用及前后张力计算和调节作分析与讨论。 Tension changes directly affect the thickness of the strip rolling changes. Control of tension changes is a very important part in the process of leveling. In the tension control system, the control of entrance S-roll is the key and difficult point. In this paper, the function of entrance S-roll in tension control system and the calculation and adjustment of tension before and after are analyzed Discuss with.
