Problems solved by technology

[0002] The traditional spherical aluminum powder production technology is a single nozzle with an atomization assembly and grading system, because the single nozzle limits the production capacity of the whole line. If the production is increased, the only way to expand the whole line is to double the production capacity. Investment costs and production operating costs also doubled

Embodiment Construction

[0035] See Figure 1, the production process of double-nozzle atomized aluminum powder. This process uses a double-nozzle atomization chamber 1 and is equipped with two silicon carbide rods to heat the aluminum melting furnace 2 to melt aluminum ingots. The melted liquid aluminum enters the double-nozzle mist The atomization chamber is used for atomization treatment, high temperature and high pressure nitrogen is blown into the atomization chamber through the air compressor, and after cooling, the liquid aluminum liquid becomes granular. Then enter the classification system 3 for classification; the classification system adopts the mode of three-stage centrifugal classifier 6 plus one-stage cyclone collector 7 (Fig. 3), and the cyclone collector 7 is connected to dust collector 5; the circulation system adopts double balance tank 4 and double blower , connect the dust collector 5;

Abstract

The double nozzle atomizing aluminum powder production process includes the following steps: smelting aluminum ingot in aluminum smelting furnace with two heating silicon carbon rods, atomizing the liquid aluminum in double nozzle atomizing chamber, blowing high temperature and high pressure nitrogen with air compressor into the atomizing chamber to cooling liquid aluminum into aluminum grains, grading in a grading system comprising three stages centrifugal grading machine and one cyclonic collector, and circulating through a circulating system comprising double balance tank and double blower. The present invention has greatly raised production capacity, saving in investment and low production cost.

Description

technical field [0001] The invention relates to an aluminum powder production process. Background technique [0002] The traditional spherical aluminum powder production technology is a single nozzle with an atomization assembly and grading system, because the single nozzle limits the production capacity of the whole line. If the production is increased, the only way to expand the whole line is to double the production capacity. Investment costs and production operating costs are also doubled. [0003] How to further increase the output, fine powder rate and quality of aluminum powder is the goal of the new line process technology improvement. Contents of the invention [0004] In order to achieve the above objectives, the object of the present invention is to provide a double-nozzle atomized aluminum powder production process, which uses double atomized nozzles and is equipped with an aluminum powder atomization, cooling and grading system. It has been verified by pract...
