Corrugating roll is one of the most important components in corrugated carton production. Usually, it is an essential part of single facer. Corrugating rolls consist of two parts: upper roll and lower roll. The lower corrugating roll is the driving roll, which is generally fixed while the upper one is the driven roll.
Features:
1. Diameter 100-500mm, roller length 100-4000mm
2. Special 48CrMo alloy steel refined forging; A,C,B,CB,BE,E,F,G flutes; 0.06-0.08mm coating thickness
3. Adopt advanced heat treatment technology and precise machine tolls to do multi-layer process
4. Chrome plating technology and precise grinding can reduce the friction coefficient of the roller teeth, enhance the abrasion resistance, prolong the service life.
5. Design the profile flute by computer. And test the corrugated roll on our single facer before shipment.
Advanced Equipments
• With advanced intermediate frequency quenching machine to do heating treatment. After harden, the hardness reach to be more than HRC 58 and harden layer 8-12mm.
• High precision grinding machine with Siemens control system is special designed for corrugating rolls. It's important for a high precision corrugating rolls. The flute profile is formed after finish grinding.
• Special polishing mahine and technology for corrugating rolls. Smooth surface can extend the life span of hard chrome corrugating rolls.
High precision grinding machine.
