Thermo rolls

Walzen Irle GmbH is a German company that has widely used high stress applications forged steel rolls in the retrofitting of calendar thermo rolls. The company has introduced KSTV, a homogenous material like forged steel, that has a lower heat transfer rate of about 20 W/mK. The thermal helical accelerator technology (S-technology) increases the energy transfer rate in a thermo roll and decreases the temperature deviation around the circumference of the roll surface. Maintenance of thermo rolls is done without dismantling the mechanical journal and the removal of sealing unit allows access to all components in the flow of heating medium in thermo rolls. The company has also ensured an efficient operation of forged steel rolls that leads to stress and flow reduction and re-balance of calendar thermo rolls.
