Calender Machine in Paper Making Line

The advanced performance of this calender is defined by its precision-engineered core components. The hardened alloy steel hot roll, with a large 800mm diameter and mirror-finished surface, ensures effective heat transfer and extended service life. The calender incorporates a sophisticated 11-zone Controlled Crown roll supported by alloy copper hydrostatic bearings, enabling precise, profile-correcting pressure across the entire sheet width. Furthermore, the calender features a self-assembled hydraulic system with a large 304 stainless steel reservoir and high-filtration (3µ) to ensure oil purity and system stability, while the integrated PID-controlled thermal oil system maintains roll surface temperature within a precise 1°C gradient.

The machine’s capabilities are detailed in its key technical parameters:

Product & Width: For corrugated paper, 105-160 g/m², with a 4500mm sheet width.

Speed: Operates at 400-450 m/min, designed for 600 m/min.

Roll Specifications: 800mm heated roll diameter, 600mm Controlled Crown roll diameter.

Pressure & Power: Design line pressure of 60-120 kN/m, with a 180kW thermal oil heating system.

Construction: Machine centers at 6000mm, using high-grade SHD85 hard roll surface and imported hydraulic components.
