High quality Hard Chrome Doctor Roll for BHS Corrugator Machine
Doctor roll is used to control and adjust the glue volume on the
surface of glue roll. Therefore, it is essential to regulate the
gap between doctor roll and glue roll. The scrapers on the doctor
roll are used to get rid of the glue on the surface of glue roll so
that the glue roll can be used for next circulation.

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.
