The invention discloses a method and device for separating 434 aluminum
alloy composite plates, belongs to the field of nonferrous
metallurgy, and mainly solves the problem of recycling of the 434 aluminum
alloy composite plates. The preparation method comprises the following steps: firstly, melting a
coating alloy of the 434 aluminum alloy at 574-643 DEG C in a high-temperature centrifugal
machine; then centrifugally separating the
molten alloy, discharging the
molten alloy through a
liquid phase outlet
pipe, closing a centrifugal mechanism, and taking out the unfused alloy; and finally, the
molten alloy and the incomplete alloy are smelted in a
smelting furnace and poured into cast ingots. The device comprises a shell, a heat preservation layer, a PID
furnace temperature self-adjusting
system, a centrifugal mechanism, a liquid outlet mechanism, a melt deposition tank, a
liquid phase outlet
pipe, a furnace cover lifting mechanism, a feeding and discharging mechanism and a tool. According to the method, a temperature field and a
centrifugal force field are used for achieving same-grade
recovery after a
coating layer and a core layer of the 434 aluminum
alloy composite plate are effectively separated, and 3003 aluminum alloy and 4004 aluminum alloy with the same-grade quality are obtained through separation.
