随着带钢酸洗—冷轧—精整各工序直接连接工艺的推广,控制带钢张力和对带钢正确导向显得更为重要。传统的S张紧辊已不能满足要求,因而联邦德国Bandanlagen-Technik公司开发了Umlauf带钢张紧装置。 该新型带钢张紧装置具有表面复上橡胶的两条链带以及将两条链带压紧的机构。该装置工作时,链带夹紧带钢,借助于驱动马达可使轧机入口段的带钢张力提高到2000 kN,也可将驱动马达当作牵引发电机,使带钢张力减小。张力的增大、减小都是在带钢不发生弯曲的情况下,在很短的直线段中发生
With the strip pickling - cold-rolled - finishing the process of direct connection of the promotion of control of strip tension and strip the correct orientation is even more important. Traditional S-tensioning rollers are no longer sufficient, so Umlauf strip tensioners have been developed by the German-based company Bandanlagen-Technik. The new strip tensioning device has two straps that are rubberized on the surface and a mechanism to compress the two straps. In operation, the belt clamps the strip and, with the help of the drive motor, increases the strip tension in the entry section of the rolling mill up to 2000 kN. The drive motor can also be used as a traction generator to reduce strip tension. Tension increases, decreases are in the strip does not occur in the case of bending, occurred in a very short straight line segment
