Problem: Abrasion, Erosion and Corrosion
Industrial centrifugal blowers in cement plants provide ventilation of hot gases (≤ 500° C) rich with fine particle dust expelled from high temperature environments inside preheat towers, clinker ovens and clinker coolers.
At a cement plant in South America, blower fan blades mounted inside a pair of discs are fabricated from unprotected Q&T steel and not sufficiently resistant to exposure to abrasion, fine particle erosion and corrosion during service. Material loss is severe and requires replacement after only 2-4 months of service.
Solution: NanoSteel Coating and Overlay Wear Plate
A NanoSteel SHS 9192 overlay wear plate, 0.236 in (6 mm) thickness, for resisting severe abrasion is installed on fan blade and disc ID surface exposed to greatest amount of wear. A NanoSteel SHS 7170 TWAS coating, 0.039 (1 mm) thickness, for resisting fine particle erosion and corrosion is applied to the overlay wear plate and remaining fan blade and disc ID and OD surfaces. |

Result: NanoSteel Coating and Overlay Wear Plate Extend Service Life by 3x
After only 2-4 months of service, unprotected steel fan blades are worn through and must be replaced. However, fan blade and disc surfaces protected by NanoSteel SHS 9192 overlay wear plate and SHS 7170 TWAS coating show minimal wear after 12 months. |
