Abstract

The invention provides a connecting rod, a self-cooling centrifugal rotating disc atomizing powder making device and an atomizing powder making method. The connecting rod comprises a first connectingbody and a second connecting body. The first connecting body comprises a connecting cavity with an opening. The connecting cavity is provided with an inner side wall and a bottom wall. A plurality ofcooling parts are arranged on the outer wall of the first connecting body. The second connecting body is connected with the first connecting body. The connecting rod is provided with a cooling part and can prevent heat conduction. By adopting the self-cooling centrifugal rotating disc atomizing powder making device with the connecting rod, the heat of the atomizing disc structure can be preventedfrom being transmitted to a motor, and therefore the technical problem that the high-speed motor cannot be automatically cooled in real time when the high-temperature metal powder is prepared in the centrifugal atomizing process in the prior art is solved.

Description
