The Metsä Board Husum mill had problems with wear at backing roll due to the hard-coated blades wearing the rubber cover edge.
|Customer challenge||Due to wear problems the rubber-covered backing rolls had to be changed every 240-430 hours operating time.|
Polyurethane cover Valmet Coater Roll Cover CC for coater backing rolls was installed on the coating station
|Results||Valmet Coater Roll Cover CC was operated for impressive 1,530 hours – four times longer than the normal rubber-covered backing roll. After run time, the cover was still not significantly worn. Husum mill was impressed by it and ordered a second cover for their stations.|
