Tensioner is also called
tension roller group. The function of tension roll group is to realize the separation and regulation of the tension for the steel strip in continuous production line.
In continuous production line for colored steel strip, in order to meet the requirements and ensure of the continuous production process, the color coating line should be broadly divided into a number of different tension partitions, so it is very important to install and control the tensioner unit. To guarantee the stability of high speed of whole line, the tension roller group mostly adapts direct tension closed loop control, to reduce the investment and energy saving at the same time.
