Dryer Cylinder For Paper Machine Drying Section
Our dryer cylinder set offers superior performance through advanced engineering and premium materials. With HT300 cast iron shells (30mm wall thickness) and QT500-7 ductile iron shafts (1:12 taper with hydraulic removal ports), these cylinders provide excellent heat transfer and long‑term structural integrity. Seven of the 32 cylinders feature hard chrome plating (0.1–0.12mm) for enhanced wear resistance in high‑wear positions. Internal stainless steel turbulence bars optimize heat transfer and prevent condensate accumulation, while G2.5 dynamic balance ensures vibration‑free operation. Every cylinder is pressure‑tested to 1.0MPa and certified with full documentation, guaranteeing safety and reliability for continuous paper production.
