Atomized production system

Abstract

The embodiment of the invention discloses an atomized production system, which comprises a spraying device, an atomizing chamber, a nitrogen gas compression system, a nitrogen producing system, a cooling system, grading systems and ventilators, wherein the spraying device is communicated with the atomizing chamber which is communicated with a plurality of sets of grading systems; each set of grading system is respectively connected with one ventilator; the nitrogen gas compression system is communicated with a gas balancing tank and the spraying device; and the nitrogen producing system is communicated with the gas balancing tank. In the atomized production system, a cooling tube array is arranged on a ventilation pipeline; and a water-cooling jacket is arranged on equipment. In the embodiment of the invention, one spraying device corresponds to the plurality of sets of grading systems and each set of grading system is provided with one ventilator; through a plurality of tests by an inventor, the pressure of the atomized production system can reach as high as 6-12MPa and the cooling speed can reach 103-104k / s; and in addition, high-pressure gas of the atomizing device is centrally used, and thereby the conversion rate of atomizing energy is improved and further the production capacity of the atomized production system is improved.

Description

technical field [0001] The invention relates to the field of production of aluminum alloy and aluminum alloy powder, and more specifically relates to an atomization production system. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of science and technology and industrial economy in recent years, the demand for welded structural parts of aluminum alloys is increasing, and the research on the weldability of aluminum alloys is also in-depth. The density of pure aluminum is small, about 1 / 3 of that of iron, and its melting point is low. Aluminum has a face-centered cubic structure, so it has high plasticity and is easy to process. It can be made into various profiles and plates. Through long-term production practice and scientific experiments, people have grad...

AI Technical Summary

Problems solved by technology

In addition, there is only one circulating fan in the above-mentioned atomization production system, the air volume is small and the air temperature is high, and the cooling effect is poor (the spray cooling rate is basically the same)

Therefore, the aluminum alloy powder prepared by the above-mentioned atomization production system has low particle dispersion, low fine powder rate, easy adhesion of the product, and low production capacity.

[0005] In addition, the production capacity of each atomization production system is not high, and the investment is large. It must be equipped with corresponding smelting equipment, and the capital occupation rate of the power supply and distribution production plant is high.

If you want to expand production capacity, you must build a new production line to complete

At the same time, in the production process, the power and parameters of each equipment cannot be adjusted flexibly, the system classification system is single, the air volume of the fan cannot be adjusted, the cooling rate is low during production, and it is impossible to produce high-quality aluminum and aluminum alloy products with reasonable crystal phase structure.
