Abstract
A manufacturing method of an aluminum alloy with high thermal conductivity comprising steps of: preparing materials including pure aluminum ingots, silicon alloy, iron alloy and magnesium alloy; melting the pure aluminum ingots in a reverberatory furnace at two stages, melting, stirring, sampling for compositions determination; transferring the molten aluminum into a holding furnace, putting the ingots in, melting, removing slag, determining the compositions; calculating amount of the alloys to be added; melting the silicon alloy and iron alloy in the molten aluminum and analyzing the compositions; adding the ingots to cool the temperature of the molten aluminum down and then adding the magnesium alloy, confirming and making corrections if insufficient compositions; degassing and purifying the molten aluminum by adding drossing flux in the furnace and making a final compositions determination; transferring the molten aluminum into online degassing system to degas and purify; casting the molten aluminum into aluminum alloy ingots.
