Wear-resistant bushings for foundry crushers

An accessory in the crusher is called a wear-resistant bushing, which is easily worn due to various collisions during use. Once the bushing is damaged to a certain extent, the cost per ton of the crusher will be greatly increased. Therefore, it is very important to choose a suitable crusher bushing and replace the manganese steel wear-resistant bushing. However, there are many materials and many types of wear-resistant bushings. How to choose the most suitable wear-resistant set for crushers with excellent performance? Different crusher wear bushings require different materials.

The heat treatment process includes heating to above 10000°C to transform the brittle as-cast multiphase structure into single-phase austenite, followed by rapid water quenching. The single-phase austenite microstructure remains stable at room temperature, resulting in a ductile, high-strength material that resists fatigue from the crushing process. Welding areas or other heat treatments should be avoided as the material can easily revert to the brittle as-cast structure.
