Melting Electromagnetic Stirring Technology for Aluminum Industry Melting

With the rapid development of the aluminum processing industry, higher requirements are also put on the quality of aluminum processing products. The traditional manual and mechanical stirring methods can no longer meet the needs of aluminum processing and development. Therefore, the mixing is convenient and sufficient and the quality of products can be ensured. Electromagnetic stirring technology has gained more and more applications in the aluminum casting process.

Electromagnetic stirring technology has the following advantages in aluminum processing and production:

1, can make the alloy composition uniform. The magnetic stirring is sufficient and convenient, and the alloy composition of the whole furnace can be evenly distributed within 10 to 20 minutes, which avoids the difference caused by artificial stirring due to different skills, physical strengths, and even labor attitudes.

2, does not pollute the aluminum solution. Electromagnetic stirring is non-contact stirring, which has obvious technical advantages in the production of high-purity aluminum and strict control of harmful trace elements.

3, can greatly reduce the melting time and reduce energy consumption. Since the metal aluminum blackness is small and the heat transfer efficiency is not high, the implementation of electromagnetic stirring can accelerate the flow of the melt, greatly increase the thermal efficiency, shorten the smelting time by about 20%, and reduce the fuel consumption by 5% or so.

4. It can reduce the temperature difference between the upper and lower parts of the melt and reduce the production of slag. Slag is an inevitable product of the aluminum smelting process and its production is related to many factors. When the melt temperature reaches or exceeds 750oC, the slag will increase dramatically. The application of electromagnetic stirring can reduce the temperature difference between the upper and lower parts of the melt and reduce the surface temperature of the melt. Under normal circumstances, the slag can be reduced by about 20%.

5, to facilitate the slag, can reduce the number of furnace, extend the service life of smelting furnace, static furnace.

6, can reduce the labor intensity of workers, improve working conditions and improve labor efficiency.

7, to create the conditions for the automation of the aluminum casting process.
