| Rcently, our orders for electromagnet crane with slewing trolley have been surging. In this type crane, there is a special component ”slewing trolley”, Well, how is slewing mechanism been processed? | |||||||||||||
| First step: Welding | |
| workers need to weld circular rail and under layer trolley together. | |
| Second step: Milling and cutting | |
|
After welding, the workpiece will come to CNC fixed beam gantry mobile boring and milling machining center.
Here, it will take dozens of hours and several rounds of milling process. |
|
| Third step: Surface quenching | |
| ♦ Surface quenching will be carried out according to the process requirements.
♦ Do you believe it, the surface quenching of large diameter circular rail is completed by Kingda
♦ Three wheels driven under the supporting legs can assist travelcrane's automated rotary quenching machine. |
|
| ♦ Only one person is needed, to complete the quenching process independently. ♦ The sensor can instantly heat up, also can instantly cool down, Hardening depth is easy to control. ♦ Be even quality and Efficient quenching has been achieved. |
|
| ♦ The quenching process is energy-saving and environmentally friendly, achieving a dual robustness of efficiency and environmental protection |
|
After cooling |
| ► The martensitic structure in the quenched layer is fine |
| ► Good mechanical performance |
| ► Optimized the surface structure of the workpiece |
| Fourth step: Assembling | |
| After quenching is completed, come here for assembly. | |
| The scene of trolley after been assembly is quite impressive. | |
