| Abstract:The cause of zebra grains on the soft calender roll is described to the material fatigue according to material mechanics principle. There are three outer layers of the soft calender roll, i.e. the serious damaged layer which is almost 0.2 mm thick, the controlled grinding transition layer and the basic layer which maintains the material character. The methods for grinding these three layers are discussed. The soft calender roll grinding method including lowering down the temperature, recovery deformation, measuring, controlling the grinding amount and finishing is summarized. |
