Abstract (en)

The invention provides a method of in-situ self-generating aluminum-based composite material by melt control with electromagnetic stirring, including the following steps: providing a vacuum tank having an immersion tube and an air extraction port, wherein the immersion tube is configured to be immersed in an aluminum melt in an aluminum melting furnace; a graphite rotator for argon rotary blowing; an electromagnetic stirring device disposed below the aluminum melting furnace; after melting the pure aluminum or aluminum alloy matrix in the aluminum melting furnace, adding reaction salt and reaction promoters to react; immersing the immersion tube of the vacuum tank into the aluminum melt and vacuuming the vacuum chamber; dropping down the graphite rotator and the rotating rod passing through the vacuum chamber of the vacuum tank via the sealing bearing at the top of the vacuum tank and inserting the spray head into the bottom of the aluminum melt for argon rotary blowing; starting the electromagnetic stirring device for electromagnetic stirring of the aluminum melt.
