Mining machinery often operates in harsh environments such as high temperature, high humidity, and high salt spray, so wear plates need to have stable environmental adaptability.
Chocky bars are modular protective components made of high-wear-resistant alloy materials, widely used in high-wear areas such as excavator buckets, chutes, and crusher feed inlets.
Precision castings for mining machinery require extremely high internal density when operating under harsh mining conditions.
Non-destructive testing techniques such as ultrasonic flaw detection and infrared thermal imaging are used to regularly evaluate the bonding status between wear plates and the substrate.
The heating rate needs to be adjusted according to the size and material of the casting to avoid cracking due to thermal stress concentration.
Arrange welding layers reasonably, such as multi-layer and multi-pass welding, and refine the weld structure of the previous layer through the heat treatment of the subsequent weld layers to improve the overall performance.
