Steam showers play a vital role in modern corrugated board production. It not only improves productivity, but also significantly improves the quality of the board. In this article, we'll take a closer look at how steam showers work, what their advantages are, and how they are used in corrugated cardboard production lines.


What is a steam shower?
A steam shower is an auxiliary device used in corrugated cardboard production lines to regulate the moisture and temperature of the cardboard by spraying high-temperature steam. Its main purpose is to provide the necessary heat and humidity during the cardboard molding process to ensure the bonding quality and surface flatness of the cardboard.


Working Principle of Steam Shower
The steam shower is usually installed near the preheater and heater of the corrugated board production line. Steam is evenly sprayed onto the board surface through a series of nozzles to regulate the temperature and humidity of the board. The specific process is as follows:


Steam Generation: Steam is generated by a boiler or steam generator and piped to the spraying device.
Steam Distribution: Steam enters the shower and is evenly distributed to the nozzles through the distribution system.
Steam injection: The nozzles inject high-temperature steam uniformly onto the surface of the cardboard, rapidly increasing the temperature and humidity of the cardboard.
Temperature and humidity regulation: The steam injection softens the cardboard fibers, increasing the adhesion and surface flatness of the cardboard.
Advantages of Steam Sprayers
Improvement of bonding quality: Proper temperature and humidity allow the cardboard fibers to bond better, avoiding delamination and blistering problems.
Improve board flatness: Uniform steam spraying reduces wrinkles and ripples on the board surface and improves the appearance of the product.
Increased productivity: By optimizing the physical properties of the board, steam showers can speed up production and reduce scrap.
Save energy: Modern steam showers are often energy efficient, utilizing steam to reduce production costs.
Application examples of steam showers
In practice, steam showers play an important role in corrugated board production lines. Below are a few examples of successful applications:


Improving bonding strength: After a corrugated cardboard manufacturer introduced a steam shower, the bonding strength of the cardboard was significantly improved, and the product qualification rate increased from 85% to over 95%.
Improvement of surface quality: Another corrugated cardboard manufacturer has significantly reduced the number of wrinkles on the surface of the cardboard with the introduction of a steam spraying device, resulting in a significant increase in customer satisfaction.
Increased production speed: A large corrugated board mill optimized its steam shower system to achieve a 20% increase in production line speed and a 15% reduction in energy consumption.
How to Select and Maintain a Steam Shower
Selecting the right steam shower requires consideration of the following aspects:


Equipment specifications: Select the right steam shower based on the size of the line and the specifications of the cardboard to ensure that it meets production needs.
Nozzle design: choose the equipment with reasonable nozzle design and even spraying to ensure the best steam spraying effect.
Control system: A modern control system can accurately regulate the temperature and flow rate of the steam and improve the automation level and ease of operation of the equipment.
Maintenance: Regular inspection and maintenance of the equipment to ensure the normal operation of the steam spraying device, to avoid production stagnation caused by equipment failure.
Conclusion
The application of steam spraying devices in corrugated cardboard production lines has greatly improved production efficiency and product quality. By reasonably selecting and maintaining this equipment, enterprises can realize higher production efficiency and market competitiveness. Whether it is to improve bonding strength, surface quality or energy savings, steam showers are an important and indispensable part of the corrugated board production process.
