Description

Technical Field

[0001] The utility model relates to the technical field of cooling iron silicon aluminum alloy powder, in particular to an iron silicon aluminum alloy powder plasma atomization mechanism. Background Art

[0002] With the rapid development of magnetic materials, Sendust material has a higher cost-effectiveness among many magnetic materials due to its higher magnetic induction intensity and lower loss. It is widely used in power inductors, AC inductors, output inductors, line filters, power factor correction circuits and other switching power supplies. In the process of processing Sendust alloy powder, it is necessary to atomize and cool the Sendust alloy powder.

[0003] In the prior art, after cooling down the iron-silicon-aluminum alloy powder, the iron-silicon-aluminum alloy powder will enter the interior of the storage box, and then the formed iron-silicon-aluminum alloy powder (i.e., spherical powder) will be stirred by a stirring rod, thereby completing the processing of the formed iron-silicon-aluminum alloy powder; however, since the formed iron-silicon-aluminum alloy powder is stored inside the storage box, and the iron-silicon-aluminum alloy powder is not completely cooled and formed, part of the iron-silicon-aluminum alloy powder will have a certain viscosity, and the iron-silicon-aluminum alloy powder will stick to the inner bottom of the storage box, thereby forming an accumulation, and the accumulated iron-silicon-aluminum alloy powder may also affect the subsequent cooling and storage of the iron-silicon-aluminum alloy powder, thereby causing the inner bottom wall of the storage box to be unable to be cleaned while the stirring rod is rotating. If cleaning is required, the operator needs to operate, which is inconvenient to use. In view of this, we introduce a plasma atomization mechanism for iron-silicon-aluminum alloy powder.
