AK-Steam box

Operation Principle
Before the paper web enters the nip zone, treated steam condensate is sprayed onto the paper surface. As the temperature of the paper web rises, the viscosity and surface tension of its moisture decrease, enhancing fluidity. This enables better dewatering performance when the paper web passes through the nip zone. Precision steam servo valves, combined with optimized steam injection holes, improve cross-machine quality.

Product Advantages

Increases the dryness of the paper web exiting the nip zone by 1–3.5%.
Enables higher machine speed and increased production.
Reduces steam consumption in the drying section.
Enhances strength, minimizes paper breakage, and ensures more stable paper web operation.
Lowers nip zone pressure.
Alleviates re-wetting caused by capillary force.
Increases curl humidity.
Reduces oily adsorption.

Advantage Comparison

Compared with Traditional Steam Boxes

The heating area of the steam box is divided into zones with a width of 50 mm to 300 mm, each independently controlled by a steam servo valve. Precise steam flow control, combined with a reasonable distribution of steam injection holes, allows steam condensate to penetrate the paper web in an optimal state, improving cross-machine quality while saving steam.

Compared with Steam Boxes Using Pneumatic Steam Valves

With position display.
Repeat positioning accuracy of ±0.02 mm.
Electric servo valves feature high homogeneity, avoiding the issue where pneumatic valves may have different openings despite the same air pressure.
Online fault detection.
