Vacuum melting gas atomization milling device

Abstract

The invention discloses a vacuum melting gas atomization milling device. The vacuum melting gas atomization milling device comprises a smelting furnace body, at least two tundish functional modules, a moving mechanism and an atomization device, wherein a melting crucible is arranged inside the smelting furnace body; the melting crucible pours materials into the tundish functional modules through a material pouring electric elevator; the tundish functional modules are mounted in the position, above the atomization device, inside the smelting furnace body; the tundish functional modules can perform horizontal sliding and / or up-down lifting motion inside the smelting furnace body through the moving mechanism; the moving mechanism is used for changing the tundish functional modules for utilization; and the tundish functional modules are connected with the atomization device. According to the vacuum melting gas atomization milling device, the structure is simple; the plurality of tundish functional modules and the matched moving mechanism are adopted, so that changing between the plurality of tundish functional modules is achieved, and the problem that in the prior art, when a tundish functional module breaks down, overhauling requires to be carried out under the condition of production halt and the vacuum melting gas atomization milling operation cannot be continuously carried out is solved; and the operation is convenient.

Description

technical field [0001] The invention relates to a gas atomization pulverization equipment, in particular to a vacuum smelting gas atomization pulverization equipment. Background technique [0002] Atomization powder making technology is the main method for producing metal and alloy powders. Atomized powder has the advantages of controllable powder particle size, low oxygen content, low production cost and adaptability to the production of various metal and alloy powders.

With the emergence of new powder metallurgy technology and materials and the application of powder raw materials in surface engineering, electronics, chemical industry, laser rapid prototyping, military and other industries, the requirements for alloy powders are developing in the direction of fineness, high purity and spherification. The driving force promotes the continuous development of powder atomiza...

AI Technical Summary

Problems solved by technology

The integrated smelting and current-limiting pouring atomization equipment for preparing metal powder has a single structure of the hollow rod-shaped valve core, the current-limiting casting valve seat and the current-limiting diversion column. The processing of powder needs to be interrupted before maintenance can be carried out, continuous production cannot be realized, which reduces the efficiency of atomized powder making
