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.
Applications
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.
Features
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.
Benefits
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
Made from 50CrMoA forged alloy steel sourced from Zhongyuan Special Steel, a top-tier Chinese supplier. The material offers high strength, wear resistance, and thermal stability, ideal for high-speed corrugating applications.

Surface Hardening Process
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.

Packaging
Vacuum-sealed with anti-rust protection and packed in shock-resistant wooden crates, suitable for long-distance sea transport.
Inspection Process
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.
What types of coatings are used on corrugating rolls for board production?
We offer hard chrome and tungsten carbide coatings, with a thickness ranging from 0.06 to 0.08 mm. Corrugating rolls can be processed with widths up to 3600 mm and diameters up to 600 mm.
Which heating methods are commonly used for corrugating rolls?
Available heating options include peripheral heating, siphon pipe steam heating, electric heating, and oil heating. Each method is selected based on the performance needs of the single facer.
What vacuum systems are used in corrugating rolls?
Both external and internal vacuum systems are available. Slot designs include diagonal cuts, straight slots, and micro slotted channels to match different production setups.
What surface treatments are applied to corrugating rolls?
We apply a combined heat treatment process that includes nitriding, medium frequency quenching, tempering, and cryogenic treatment. This results in surface hardness levels exceeding HRC 60.
Can you design flute profiles based on customer requirements? What are the advantages of your flute types?
Yes, we offer customized flute profile designs tailored to board height, stacking strength, and take-up rate requirements. Compared to standard designs, our flute profiles reduce paper usage by 0.5%–1% without compromising board strength. UV and UVV flute types are also available to enhance flat crush resistance, improve bonding, and reduce glue consumption.
