Extending Service Life of Blower Fan Blade using Coatings and Overlay Wear Plate by NanoSteel Co.

The NanoSteel Company is an advanced materials company which has created a unique and proprietary portfolio of nanotechnology based and environmentally friendly steel alloys that greatly increase the value of steel in most of today’s industrial applications.

Product success has been through the development of Super Hard Steel® (SHS) alloys which feature nanoscale microstructures. SHS alloys are for use as metallic coatings within power generation, mining, cement, concrete and oil & gas industries.

Applied by thermal spray and weld overlay processes, NanoSteel SHS alloys dramatically increase the service life of industrial components subject to wear and corrosion environments, eliminating the need for costly alternatives and environmentally dangerous chrome plating.

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.

NanoSteel Coating and Overlay Wear Plate

NanoSteel® overlay wear plate solution, 0.236 in (6 mm) thickness, for resisting severe abrasion is installed on fan blade and disc surfaces exposed to greatest wear. A NanoSteel coating solution, 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 surfaces.

Distribution of hot gases (=500°C) inside industrial centrifugal blower.

Unprotected steel fan blades are worn and must be replaced after 2-4 months.

NanoSteel overlay/coated wear plate & fan surfaces after 12 months.

NanoSteel Coating and Overlay Wear Plate Extend Service Life by 3-Fold

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 with NanoSteel coating and overlay wear plate solutions show minimal wear after 12 months.
