The wear-resistant parts of crushers play a crucial role in the construction of a large number of engineering infrastructure and the extraction of resources and energy with the development of China's modern economic construction. Abrasion resistant parts are indispensable in crushing equipment such as crusher, pulverizer and vertical mill. When these equipment crush various hard materials such as cement clinker, limestone, feldspar, Baryte and coal, due to the friction of materials, especially raw materials, cement, clinker and slag, which have high hardness and poor grindability, and often contain some hard impurities, such as quartz stone, iron blocks, etc., grinding rollers, grinding discs The wear of wear-resistant components such as extrusion rollers is quite severe. Therefore, higher requirements have been put forward for the wear resistance of wear-resistant components.

The wear resistance of wear-resistant parts mainly depends on their casting materials. In the current wear-resistant material market, low-cost high manganese steel or ultra-high manganese steel is used as the matrix material for large wear-resistant parts, and hard alloy or ceramic particles are composite embedded in their working parts, making the wear surface of bimetallic composite wear-resistant parts have excellent wear resistance, while the non wear surface has excellent plasticity and impact toughness.
