What are the online repair technologies of rotor hammer disc?

Using ZD3 coated covered electrode surfacing, the rotor hammer disc can be repaired online, and the surfacing height reaches the original size. There is no need for preheating before welding, which has good toughness and crack resistance, and the surfacing layer has no crack and peeling, and the wear resistance can be improved by more than one time. The hammer disc (also called rotor disc) of hammer crusher is mainly used to hang the hammer head and play a supporting role. Although the contact surface with the material is relatively small, the smaller particles flying out of the hammer crack are very serious, which leads to the rapid wear of the hammer disc, and it must be replaced when it is serious, which brings great inconvenience to production. If a layer of wear-resistant alloy can be surfacing on the surface of the hammer disc, the service life of the hammer disc can be effectively prolonged and the operation rate of the equipment can be improved.
