Abstract

The invention relates to a metal powder preparation device and method. The device consists of a control system, a smelting system, a vacuum system, an atomizing chamber, a pressure control system, a dust removing system and other parts. An atomizer in the atomizing chamber includes an atomizing nozzle, a flow nozzle and a melting body disperser; the atomizing nozzle and the flow nozzle are positioned above the melting body disperser, the central line of the atomizing nozzle is superposed with the central line of the melting body disperser and the central line of the flow nozzle, and the flow nozzle is installed at the bottom of a smelting chamber and stretches into the atomizing chamber. The method includes the steps that metal is fed into a furnace, heating and smelting are carried out onthe metal, melted bodies are ejected into the melting body disperser in the atomizing chamber under the action of the gravity and gas pressure and dispersed into liquid drops, the liquid drops are atomized into finer liquid drops, and then the finer liquid drops are cooled and solidified into metal powder. The metal powder preparation method has the advantages that the controllability of powder size is great, the powder size distribution is narrow, the furnace is not likely to be blocked, energy is saved, and the environment is protected.

Description

technical field

[0001] The invention relates to the technical field of powder metallurgy, in particular to a device and method for preparing metal powder by an atomization method. Background technique

[0002] Metal powders are used in almost all industrial fields. Among them, because of their excellent physical, chemical, and mechanical properties, rapidly solidified metal powders have gained great popularity in many fields such as machinery, electronics, chemical industry, military industry, and aerospace. important and widely used. The gas atomization method is one of the important methods for the preparation and large-scale production of rapidly solidified metal powders. However, the existing gas atomization methods have problems such as wide powder particle size distribution, low powder extraction rate, high energy consumption, and easy furnace blockage. In U.S. Patent No. 5,242,508, a typical method for preparing metal powder is proposed, that is, a close-coupled gas ...
