Abstract

The invention discloses a method for preparing metal powder suitable for 3D printing. The method comprises the steps that (1) metal to be melt is put in a smelting crucible; (2) the smelting crucible is evacuated with equipment till 6.63*10<3>Pa, is charged with a high purity inert gas, and the metal is melt in the smelting crucible under the protection of inert gas atmosphere; (3) the melt liquid metal is guided in a tundish crucible of a high speed by a guiding nozzle of the bottom of the smelting crucible, the liquid metal flows to the circumferential surface of the tundish crucible under centrifugal force, and the liquid metal is cast into metal drops through outflow holes of the circumferential surface; (4) the metal drops form spherical shapes under the action of surface tension, fly in a furnace chamber and are cooled and solidified into metal balls. Moreover, the invention also provides a device for preparing the metal powder suitable for the 3D printing, which solves the technical problem in the prior art that the atomization effect of metal powder preparation method is still not ideal.

Description

technical field [0001] The invention relates to the field of 3D printing additive manufacturing and the field of powder metallurgy technology, in particular to a metal powder preparation method and device. Background technique [0002] With the development and innovation of processing technology, powder materials are more and more widely used in the fields of automobile, metallurgy, aerospace, aviation, transportation, biomedicine, etc. needs are more urgent. High-performance metal powder has the characteristics of good fluidity, narrow particle size range, and uniform composition, which requires advanced preparation technology to obtain. At present, the main method of producing metal spherical powder at home and abroad is the atomization method. The domestic atomization powder making technology level is far behind that of foreign countries, and the prepared metal powder has a large particle size range. Particle size, production efficiency is extremely low, and there are d...
