Hot roll ends

1. Ensure that stack rolls are lined up correctly.
— an out of line roll tends to move sideways and “pushers” are sometimes fitted over the ends of journals.
— pushers run on ball bearings and have screw adjustments to keep the rolls in line.
— pushers are required more frequently on the lower rolls.
2. Stagger the rolls by offsetting them, i.e., alternately slightly closer and slightly further away from the dryer section.
3. Ensure that water and grit do not get into the bearing box.
— if this happens, drain and refill the box with fresh oil.
— if necessary, change the bearing.
