The cooling roller is used to cool down the film after horizontal drawing to ensure its stable shape and performance. It is one of the important roller types in the traction section. Usually, the traction section has three cooling rollers, chrome-plated, anti-stick and anti-corrosion cooling rollers.

1.After the TDO , the cooling roller is chrome coating,suitable line speed 600m/min ,width 11000mm
Then the next is anti-stick coating cooling roller ,suitable line speed 600m/min ,width 11000mm
After corona station , it will be anti-corrosion cooling roller ,suitable line speed 600m/min ,width 11000mm
Because during the corona treater roller running, it will release ozone, which have corrosion , once ozone enter into the roller body, which will generate the coating bump and shed
once occur this kind of problem, it need to change the roller completely ,in only repair the surface, the bump and shed problem will occurred again after a while .
