Water Cooled Furnace Rolls for Continuous Annealing Furnace | 1.4848 Alloy Roll Manufacturer

⚙️ High Performance Water Cooled Furnace Rolls for Continuous Annealing Lines
Wuxi Junteng Fanghu Alloy Technology Co., Ltd. (FH®) manufactures water cooled furnace rolls specially designed for continuous annealing furnaces, continuous galvanizing lines (CGL), and heat treatment production lines.

The water cooled furnace roll shown is manufactured from 1.4848 heat resistant stainless steel (equivalent to AISI 310 / GX40CrNiSi25-20), featuring excellent high-temperature strength, oxidation resistance, and thermal fatigue resistance.

By integrating an internal water cooling structure, these furnace rolls maintain stable operating temperatures in high-temperature furnace zones, significantly improving roll service life and reducing deformation, bending, and surface deterioration during continuous operation.

💧 1. Internal Water Cooling Structure
The furnace roll adopts a specially designed internal cooling channel system.
During operation, cooling water circulates inside the roll shaft and body, effectively reducing the roll temperature and controlling thermal expansion.

Benefits:
✔ Reduced roll thermal deformation
✔ Improved dimensional stability
✔ Extended operating lifetime
✔ Suitable for continuous high-temperature production
