Tensioner – color coating line
Tensioner is also called tension roller group, it commonly known as S roll and has been widely used in strip continuous production line, such as galvanizing line, heavy coil line, prepainted steel coil production line and so on. The function of tension roll group is to realize the separation and regulation of the tension for the steel strip in continuous production line.
Tension roller works: wrapped the steel strip around the tension roller and create friction force in its surrounding contact area, to make the exit and entrance generate tension difference so as to changing the tension value of steel strip in the entry or exit and realize the tension control unit.
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.
GEIT can design and manufacture the tension roller according to different requirement. following is some common type for your reference:
Diameter: 350-1300mm
Press roller: 1-4 press rollers. diameter of 200-350mm
Driven by cylinder or hydraulic cylinder
Power: servo or dedicated varible-frequency AC motor.
