Challenge: Mining dump truck (mine truck) compartments need to withstand the impact and sliding friction of hundreds of tonnes of ore falling from a high altitude, and the working environment is extreme. Ordinary steel plate will be pitted, worn thin or even torn in a short period of time, resulting in frequent repairs and high operating costs.
Solution: NM400/NM450 high strength wear-resistant steel plate is used to manufacture the bottom and side plates of the carriages. Its excellent abrasion resistance (4-6 times that of ordinary steel) effectively resists impact abrasion, and its excellent toughness prevents cracking and ensures structural safety under heavy loads.
Case effect: After using wear-resistant steel plate carriages on 220-tonne ore trucks in a large iron ore mine, the life of the bottom plate was extended from 8 months to more than 20 months. Maintenance downtime was reduced by 60%, and the annual maintenance cost of a single truck was saved more than 100,000 yuan, and the attendance rate and transport efficiency were significantly improved.
Core Value: Provide critical component protection for large-scale mining equipment, significantly reducing whole-life operating costs through extreme service life extension.
