Introduction of Peripheral Heating Corrugating Rolls
The Peripheral Heating Corrugating Roll is a new type of steam heating structure corrugated roller, which includes a hollow cylinder and a shaft head fixed and sealed at both ends of the cylinder. The middle of the end face of the shaft head is equipped with a through hole, which is connected to the internal space of the cylinder.
A certain number of steam pipe holes are evenly arranged on the end face of the cylinder body. The steam pipe hole is equipped with a steam pipe. The two ends of the steam pipe are connected with a steam pipe installation plate, which is fixedly connected to the end face of the cylinder.
The peripheral heating system and drilled corrugated roller developed by Zhejiang Yonghui have been successfully installed in many corrugated paperboard manufacturers, especially in important areas that require high-speed and efficient production.
Advantages of Peripheral Heating System
1.It can achieve rapid heating within five minutes.
2.The deformation of the corrugating roll is small, and its service life is 20% longer than that of traditional corrugating rolls.
3.It can save more than 10% of energy.
4.The steam continuously generates heat while circulating in the pipeline and will not condense.
5.The running speed of the corrugating roll has been increased from 150 to 160 meters per minute to 200 to 400 meters per minute.
6.It has improved the functions of induced steam heat dissipation, rapid preheating and temperature adjustment of traditional corrugating rolls to meet the constantly changing production requirements.
7.It maintains a uniform temperature curve throughout the working width, so the diameter consistency and the adhesion is better.
8.The cardboard does not deform ("banana effect") when the corrugating roll stops.
9.It has the good condensation reflux, is easy to maintain, and does not require the use of a siphon.
