The downtime for perform maintenance of large metal crusher is one of the most important issues. Many users have great deal of misunderstanding on the judgment. Large metal crusher is with a bit larger noise at run time compared to small devices, so the traditional judging from noise is with great difficulty. Therefore, in addition to provide repair according to a fixed time and frequency of accidents, some assistant judgment methods are required at runtime.
For metal crusher, some forging parts need no longer final heat treatment, so in order to obtain nice synthetic mechanical property, tempering is appropriate. For large forgings, heat treatment is used for processing eliminates stress, reducing hardness, preventing spots on the chemical composition and forgings, as well as refining forging organization.
Under normal conditions, the feeding of large metal crusher should be uniformly and evenly, so once the feeding speed has dramatic change or feeding materials are irregular, the metal crusher needs to be shut down for maintenance. Sometimes, if the device shakes fiercely when it is running, and materials spill from feeding port, the metal crusher also needs to be shut down for maintenance.
Commonly used forging and heat treatment technology of metal crusher are annealing, tempering, quenching and tempering and isothermal normalizing, etc. For forgings parts needn’t ultimate heat treatment, the required mechanical performance requirements should be guaranteed.
