在带钢的轧制过程中,张力的波动将直接影响带钢成品的板形及厚度公差。因此,卷取机的控制系统不仅在稳速轧制过程中,而且在加、减速的动态过程中均应保持张力一定,即恒张力轧制。这对保证正常生产和提高产品质量都是很必要的。 During the strip rolling, the fluctuation of tension will directly affect the strip shape and thickness tolerance of the finished strip. Therefore, the coiler control system not only in the steady rolling process, but also in the acceleration and deceleration of the dynamic process should maintain a certain tension, that is, constant tension rolling. This is necessary to ensure normal production and improve product quality.
