Increase Roll Temperature when the Calender is Stopped
Increase the temperature by 20 to 40 degrees F when the rolls are stopped to maintain a more uniform roll surface temperature. The TCU (Temperature Control Unit) controls the temperature of the water exiting the calender not the roll surface temperature. This is an important distinction. When the calender is not actively processing rubber, i.e. during warm-up and when the calender is stopped, the roll surface is losing... --more
