一、工艺基础和控制在冷连轧线上的轧材同时通过所有的轧机,这种情况与带材热连轧机相似。不同的是,冷轧带材时要有很高的张力(50～250牛顿/毫米~2,约5.1～25.5公斤/毫米~2),张力对所选压下量具有极为重要的作用。当压下量一定并保持不变的情况下,张力愈大轧制力愈小,反之亦然。冷轧时张力之所以特别重要,因为轧制力的作用受轧辊压扁的限制。传动及其控制表明其相互间紧密相连,互相影响,这也就是电气设备的主要问题。
First, the process foundation and control of the rolling line in the cold-rolled line at the same time through all the rolling mill, this situation and hot strip mill similar. The difference is that the cold strip when there is a high tension (50 ~ 250 Newton / mm ~ 2, about 5.1 ~ 25.5 kg / mm ~ 2), the tension on the selected amount of reduction has a very important role. When the reduction is constant and unchanged, the greater the tension, the smaller the rolling force, and vice versa. Tension is particularly important during cold rolling, because the effect of rolling force is limited by roll crushing. Transmission and control that they are closely linked to each other, mutual influence, which is the main problem of electrical equipment.
