Stretch joint for roll seals
Compatible with high-temperature fluids such as HN gas! Expansion joints for steering rolls and Hars rolls.
The "expansion joint for roll seals" is a product that accommodates large expansion and displacement due to our unique structure. It was developed for sealing between the roll shaft and furnace wall for the transportation and trajectory correction of thin steel plates in cold rolling plants (continuous annealing furnaces and surface treatment) in steel manufacturing plants. In continuous annealing furnace equipment and devices, it is used for sealing rolls, including "steering roll," "tension pickup roll," and "hearth roll," to ensure stable feeding of steel plates. 【Features】 ■ Compatible with high-temperature fluids such as HN gas ■ Accommodates large expansion and displacement due to our unique structure ■ Developed for sealing between the roll shaft and furnace wall ■ Expansion joints made of non-metallic and metallic materials *For more details, please refer to the PDF document or feel free to contact us.
basic information
【Other Features】 ■ For Steering Rolls - Used as seals for adjustable rolls to consistently feed steel sheets. - Various types are available that enhance heat resistance by doubling the internal water-cooling coils and expansion joints to supply cooling gas. ■ For Tension Pickup Rolls - Used as seals for rolls that apply tension to and finish steel sheets. - Many unique shapes developed by our company are used due to the requirement for ultra-low reaction forces. ■ For Hars Rolls - Used as seals for rolls that transport steel sheets in heating furnaces. - Designed to follow the movement and displacement of the rolls to prevent slip and wandering. *For more details, please refer to the PDF document or feel free to contact us.
