How to maintanance the hard chrome plated roller to extend the
lifetime? Pls follow our suggestions.
⇒Store
1. Store in dry places.The surface of corrugating rolls is not
compact structure. The permeation and corrosion of water and steam
will cause unusual falling off of coating.
2. Apply silicon oil. The silicon oil is valid for 3 months. If you
don’t use corrugating rolls for a long time, silicon oil must be
applied to the rolls regularly to avoid unusual falling off of
coatings caused by the permeation and corrosion of water and steam.
3. Keep the surface clean. If you put the corrugating rolls in the
warehouse, the surface should be cleaned and applied silicon for
later use.
⇒Clean
1. Don’t wash the corrugating rolls directly when the rolls are
hot.
2. After the corrugating rolls cool down, wash the rolls by water
or gas.
3. Clean the glue and paper scraps on corrugating rolls after
production to avoid scratches of coatings.
4. After cleaning, apply silicon oil on corrugating rolls.
⇒Adjust
1. Inspect the balance of corrugating roll regularly, at least once
a month.
2. Inspect the gap among corrugating roll, glue roll and pressure
roll to avoid abrasion.
3. When installing corrugating rolls, mind the small gap between
corrugating rolls and suction hood which will cause abrasion of
corrugating rolls and aluminum plate from suction hood.
4. The copper knives will loosen with the movement of machine. The
knife in “T” position will scratch the coating on two sides of
grooves. So fix the cooper knives regularly.
5. In the premise of assuring corrugated board quality in real
production, it’s better to use smallest oil/air cylinder pressure
both of corrugating roll and pressure roll.
6. When changing wide width to small width in real production,
reduce oil/air cylinder pressure both of corrugating roll and
pressure roll accordingly to avoid abnormal abrasion caused by
excessive pressure. Especially the direct abrasion between
corrugating rolls and pressure roll in paperless areas will cause
falling off of coatings.
⇒Heat
1. Start the corrugating rolls before filling in steam to avoid
abnormal deformation.
2.Check the temperature of corrugating roll and pressure roll
regularly to avoid temperature decrease caused by accumulation of
condensate water.
3. If the temperature is abnormal, please check and keep the
correct position of siphon to let condensate water out
successfully.
