[0002] Ductile iron castings are parts made of ductile iron and are widely used in the industrial field. After the ductile iron castings are cast, a series of treatments are required to eliminate casting stress, improve structure and performance, improve surface quality, ensure dimensional accuracy and meet use requirements.

[0003] At present, ductile iron castings need to be completely cooled before post-processing operations such as defect repair, surface treatment and heat treatment can be carried out. Turnover operations are required between each treatment, which makes the processing continuity of ductile iron castings poor, and further leads to low post-processing efficiency of ductile iron castings.

[0016] As a further description of the above technical solution:

[0017] The mobile power source is provided with a controller, and the controller is provided with a control button. The controller and the control button are both electrically connected to the two driving motors.
