对于较薄带钢的冷轧,通常是在可逆式冷轧机上应用小张力进行轧制的。其张力选用的大小主要依据钢质、板宽、板厚等参数。一般是所轧带钢越薄,越软,使用的张力越小。然而,小张力在轧制中极不稳定,会降低轧制精度。为此,轧制工艺要求薄带小张力轧制时,必须保持张力恒定。该轧机原张力调节系统,其张力波动量很大,特别是轧制0.5mm以下薄带时,经常发生松套、蹦带和断带事 For thin strip cold rolling, cold rolling is usually performed on a reversing cold mill. The tension of the size of the main selection based on steel, board width, thickness and other parameters. Generally the strip is thinner, softer, the smaller the tension used. However, the small tension in the rolling is very unstable, will reduce the rolling accuracy. To this end, the rolling process requires a thin strip of small tension rolling, the tension must be maintained constant. The original tension regulating system of the rolling mill has a great fluctuation of the tension, especially when the rolling is carried out on the strip below 0.5mm, loose sleeves,
