Soft Calender used in Paper Machine
The soft roll calender is mainly composed of a cold cast iron roll which can be heated to regulate temperature and a soft roll which can control height and coated with elastic materials on the shell. The width of the soft roller pressure area is up to 5-10 mm, which is 5-8 times of that of the general calender.
The auxiliary system includes: heating system, floating roll hydraulic control system, hydraulic cylinder control system, soft roll surface temperature control system.
❶ Wide pressure area, less pressure on the paper, the paper density is uniform, full-width smoothness and gloss are consistent, small difference on both sides, good
ink absorption, strong printability.
❷ It can replace the general calender to install in the paper machine before reeling, so that the paper to obtain a higher performance.
❸ Wide application range, suitable for coated and uncoated paper.
❹ With self-protection function, various protective measures can effectively avoid the damage of equipment caused by abnormal production or wrong operation, so that
the maintenance costs can be saved.
