High quality C Flute Tungsten Carbide Corrugating Rolls for Single
Facer
1. Advantages
☆ The domestic first-class technology and core operating team, each
member has rich experience with processing more than 5000 sets of
corrugated roller. Depending on the mature stable Taiwan craft
technology and the advanced international technology, we offer the
optimized design of corrugating roll flute profile totally
according to costumer’s requirement.
☆ The CNC intermediate frequency heat treatment quenching machine
adopts the foreign corrugating roll quenching technology and makes
the hardness of the substrate reach more than HRC58 degrees,
meanwhile it retains the toughness and maximizes the anti-thermal
deformation of substrate to ensure the stability of corrugating
rolls.
☆ The leading domestic high precision and high performance CNC
corrugating roll precision grinders, lathe, planer, and other
equipment are equipped with Germany's Siemens control system,
increase grinding accuracy in the maximum.
☆ With the mature of tungsten carbide plating technology, the most
advanced tungsten carbide coating equipment Praxair JP8000 , as
well as high quality imported Praxair tungsten carbide powder, the
abrasion performance of corrugating roll is extreme and maximize
the extension of the service life of the corrugating roll.
2. Adjust Well
Adjusting is very important to the quality of cardboard and rollers
lifetime.
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.
