Abstract
PURPOSE: To prepare a high purity aluminum, by using very simple equipment and operation to cool molten aluminum in a crucible from the bottom and to draw up a stirrer while stirring in the crucible in accordance with the solidification growth of the aluminum.
CONSTITUTION: The molten aluminum to be purified having a temperature of 658W695°C is thrown into graphite crucible 1 and graphite stirrer 3 is placed in the crucible. A cooling gas such as air is injected 8 to the bottom of crucible 1 to adjust the bottom temperature to a temperature of 650W690°C, thereby initiating the aluminum solidification. In this case, the operation is performed at a solidification growth rate of 0.1W2.5mm/sec, the revolution number of stirrer 3 being set at a value of 40W350r.p.m. During the period, the solidification growth rate of aluminum is determined by adjusting the drawing up rate of stirrer 3 based on the result. At the time when the solidification amount in accordance with the desired purity of purified aluminum is reached, stirrer 3 is lifted and immediately impure mother liquor remaining in the leadle is removed. Thereby, the solidified layer of the titled high purity aluminum is obtained.
