Skip Car Life Increase By Using Overlay Wear Plates

NanoSteel Company is a sophisticated materials company, which has formed an innovative and proprietary eco-friendly steel alloy product line based on nanotechnology that significantly enhances steel value in most of today’s industrial applications.

The company’s products have been successful mainly due to the development of super hard steel alloys that feature nanoscale microstructures. These SHS alloys are suitable for applications such as cement, mining, concrete, oil and gas and power generation.

Nanosteel SHS alloys are applied using thermal spray and weld overlay processes, significantly increasing the service life of industrial components that are subject to corrosion and wear environments, making costly alternatives and environmentally dangerous chrome plating unnecessary.

Industrial Wear Problem

Skip cars are utilized in underground mining for the transportation of ore in process from one station to the next. During loading and unloading, the wear plate present in the cars is subjected to sliding abrasion and impact.

NanoSteel Overlay Wear Plate Increasing Life of Skip Car Deflector

In order to improve the skip car deflector life and reduce surface material loss,  mines can now install NanoSteel overlay wear plate of 1/2 inch thickness (3/16 inch overlay on 5/16 inch substrate), for resisting impact and sliding abrasion.

Figure 1. NanoSteel overlay wear plate after deflecting 410,000 tons and exceeding Q&T plate life by 1.2x

Figure 2. NanoSteel overlay wear plate has exceeded Q&T plate life by 1.8x

Figure 3. Nanosteel overlay wear plate has exceeded Q&T plate life by 2.9x

Conclusion

Once more than 1 million tons of ore are deflected by the overlay wear plate, it is removed from service and used for maintenance. This shows a service life increase of 2.9x over 500 Brinell quench & temper (Q&T) monolithic wear plate (5/8 inch thickness), and up to 2x over chrome carbide (CrC) overlay wear plate, 5/8 inch thickness (5/16 inch overlay on 5/16 inch substrate). Once it is kept back for service, mine engineers expect that the plate will exceed Q&T plate life by 4.3x before requiring replacement.
