Combined device for preparing spherical metal powder by gas atomization method

Abstract

The invention discloses a combined device for preparing spherical metal powder by a gas atomization method. The combined device comprises two or more different-types gas atomizing smelting furnaces, each smelting furnace is detachably and correspondingly connected with two or more atomizing towers, and each atomizing tower is provided with a detachable powder collecting device; and the combined device further includes an annular guide rail, the annular guide rail is provided with moving brackets corresponding to the atomizing towers, each atomizing tower penetrates through one moving bracket,and the two or more different-types gas atomizing smelting furnaces are distributed and erected above the guide rail. The combined device is not limited by the production conditions of the single gasatomizing smelting furnaces and atomizing towers, and the different gas atomizing smelting furnaces and atomizing towers can be quickly selected to be configured. In the case of ensuring the purity and morphology of the powder, it is possible to produce a plurality of types of powders in the same production system, and the production efficiency and the utilization rate of the equipment are improved.

Description

technical field [0001] The invention relates to the field of powder metallurgy, in particular to a combined device for preparing spherical metal powder by gas atomization. Background technique [0002] With the gradual maturity of technology, 3D metal printing can be applied in more and more fields, including: aviation, automobile, medical, mold, machinery, jewelry and many other fields have their own needs. Technology manufactures spare parts. Various high value-added industries continue to introduce 3D metal printing technology to meet market demand. According to relevant market research reports, the 3D metal printing market is expected to exceed $2 billion by 2023. Therefore, it is foreseeable that the market demand for 3D metal printing raw materials will also increase significantly in the future. [0003] The gas atomization system is a more efficient manufacturing method for 3D printing fine metal powder. Its basic principle is the process of using high-speed airflo...

AI Technical Summary

Problems solved by technology

The molten metal is very easy to stick to the wall of the atomization tower when it is atomized by high-speed gas or cooled into a spherical powder. In order to prevent pollution between different powders, manufacturers often need to purchase or assemble multiple A complete set of gas atomization system is used to produce metal powders of different raw materials. Due to the high cost of gas atomization equipment, the flexibility or profit margin of the manufacturer's production is greatly reduced.
