Source: | Updated: Sep 12, 2016

Roller is the biggest wearing part, expensive so for reducing the cost, we should carefully maintain it.


1. Full quality test before entering into the workshop

Roller is a high technology, high value-added product, should apply quality test according to the quality standard, 

test the roller surface , end’s hardness, the hardness deviation should below ±(2-3)HS,apply ultrasonic to test 

the inside flaws, surface wave for testing surface quality, visual inspection for outside flaws.



2. Regular refacing


We should change the roller regularly for better protection even if the surface is flawless, roller working hours should 

be 50-100H,supportive roller should reface after 2000-3000h, for removing the working layer, the remover layer should 

thicker than the working layer.


3. Use the roller in the right way.

Use the roller according to the guidance, should adjust the temperature to 70-80℃ when switching rollers, cold roller 

should be at 30-50℃, should cold down in the water, the roller neck should be lubricated, keep clean, avoid rusting 

and grinding damage of iron sheet, prevent mis operation and accident.


4. Avoid roller break accident

Breaking down of roller is a destructive accident, there is normally two reasons, one is because the quality of roller

normally we can find flows in the breaking point, the other reason is from the outside and cause the roller power and 

torque is over weight, we should avoid this circumstance.
