Abstract
The invention relates to the technical field of metal material production, and particularly discloses a production device and method for metal powder. The production device for the metal powder comprises an open container used for containing molten metal, a rotating wheel located at an opening of the open container, and a driving mechanism capable of driving the rotating wheel to rotate, wherein the rotating wheel is used for enabling the molten metal in the open container to be thrown out of the open container in a liquid drop manner when rotating. By means of the production device, the problems that metal powder prepared through an existing high-pressure gas atomization method is hollow powder, poor in particle surface smoothness, uneven in powder particle size distribution and poor in particle sphericity degree can be solved, and the purposes of reducing the metal powder hollow rate and improving the metal powder particle size uniformity and sphericity degree are achieved.
Description
technical field [0001] The invention relates to the technical field of metal material production, in particular to a metal powder production device and production method. Background technique [0002] With the innovation of technology, especially with the rapid development of 3D printing technology, the demand for metal powder in the manufacturing field is more urgent, and the application of metal powder in fields such as automobiles, aerospace / aviation, and biomedicine is becoming more and more extensive. The particle size range of high-performance metal powder in the field of metal 3D printing is generally 15-53 μm, and it is required to have the characteristics of good fluidity, narrow particle size range, and uniform composition, which requires advanced preparation technology to obtain. [0003] At present, the main method of producing metal spherical powder at home and abroad is high-pressure gas atomization method. This method is to use high-pressure airflow to break ...
