Peripheral heating corrugating rolls are used in corrugating equipment to shape the fluted medium during the production of corrugated board. Unlike traditional rolls that use central steam pipes for heating, these corrugating rolls feature a modern design with multiple heating points distributed along the inner layer of the shell. This configuration enables much faster heat-up times, reaching optimal temperature in just five minutes.
Thanks to their efficient heat distribution, energy consumption is reduced by over 10% compared to conventional steam-heated rolls. The structure also helps minimize thermal deformation, which improves roll stability and overall performance. Service life is extended by approximately 20%, making them especially suitable for high-speed, high-efficiency production lines where both speed and durability are essential. These rolls are an excellent choice for plants looking to improve thermal response while reducing energy costs and downtime.
Our peripheral heating corrugating rolls are compatible with a wide range of single facers, making them suitable for both international and domestic corrugated board production lines. They can be adapted to corrugating equipment from well-known brands such as BHS, Fosber, Mitsubishi, BW Papersystems, Marquip, Peters, Isowa, Agnati, Langston, JS, TCY, West River, Hsieh Hsu, K&H, XHL, Fuli, and Wanlian, among others. Whether for high-speed or heavy-duty applications, these corrugating rolls can be tailored to meet the technical specifications and flute profiles required by different machine models.
- The corrugating roll consists of a hollow cylindrical body with sealed shaft ends securely attached to both sides.
- Each shaft is designed with a central through-hole that connects to the internal cavity of the roll.
- Several steam pipe ports are evenly distributed along the end faces of the cylinder, each housing an internal steam pipe.
- Both ends of the steam pipes are connected to mounting plates, which are fixed to the corrugating roll body to ensure stable and efficient steam distribution.
- Heats up in just five minutes, allowing faster startup and improved production efficiency
- Maintains better temperature consistency across the full working width, ensuring even diameter and stronger bonding
- Reduced thermal deformation extends service life by approximately 20% compared to conventional rolls
- Operates at higher speeds, increasing from 150–160 m/min to 200–400 m/min without compromising stability
- Delivers over 10% energy savings thanks to continuous steam circulation that minimizes condensation inside the pipes
- Improved thermal response supports faster preheating, stable temperature adjustment, and better adaptability to changing production needs
- Prevents board warping when the roll stops, effectively avoiding the “banana effect”
- Optimized condensate return system simplifies maintenance and eliminates the need for a siphon pipe

Developed in-house over 10 years, our peripheral heating and micro-perforation technology has been successfully applied to multiple internationally recognized corrugated line brands. The surface undergoes a combined treatment process that includes nitriding, quenching, tempering, and cryogenic cooling at -190°C, resulting in a surface hardness of HRC ≥ 60.
- Combined heat treatment
- Nitriding
- Medium frequency quenching
Vacuum-sealed with anti-rust protection and packed in shock-resistant wooden crates, suitable for long-distance sea transport.
The quality control system includes 12 strict steps, covering every stage from raw materials to the finished product.
The process involves:
Raw material testing → weld air-tightness → dynamic balancing → hardness, flute profile and dimensions → pressure testing → coating thickness → final inspection.
