Abstract

The invention discloses a preparation device and a method for spherical tungsten powder, relating to the preparation field of metal powder and solving the problems of complex production process and low powder degree of sphericity existing in the current tungsten powder preparation process. The device comprises a plasma torch cathode assembly and a plasma torch anode assembly which are arranged inan atomizing chamber relatively; an inlet of a water inlet pipe is arranged outside the atomizing chamber; the other end of the water inlet pipe extends in the atomizing chamber and contacts with theplasma torch cathode assembly; the outlet of a water returning pipe is arranged outside the atomizing chamber and the other end extends in the atomizing chamber and communicates with the water inlet pipe; a water cooling pipe passes through the atomizing chamber horizontally; the part of the water cooling pipe in the atomizing chamber contacts with the plasma torch anode assembly; one end of an air supply pipeline comprises two air inlets located outside the atomizing chamber; the air outlet of the air supply pipeline extends in the atomizing chamber and the distance between the air outlet andthe plasma torch cathode assembly is less than that between the air outlet and the plasma torch anode assembly; and a cyclone separator and a vacuum system communicate with the atomizing chamber respectively.

Description

technical field [0001] The present invention relates to the technical field of metal powder, and more specifically relates to a preparation device and method of spherical tungsten powder. Background technique [0002] In recent years, spherical tungsten powder has been widely used in low-temperature molten metal porous filters, ionizers, electron tube cathodes and thermal spraying. At present, chemical vapor deposition is mostly used in China to act on tungsten hexafluoride gas to produce large-sized spherical tungsten powder with a size of 40-650 μm. The production process of this method is relatively complicated, and the powder sphericity is not high. Contents of the invention [0003] The embodiment of the present invention provides a preparation device and method of spherical tungsten powder, which is used to solve the problem that the existing production process is relatively complicated and the formed powder has a low sphericity. [0004] An embodiment of the prese...
