本專利是將一結晶裝置伸入裝有高溫鋁液之容器，藉由鋁湯與結晶裝置溫度差，造成偏析凝固現象於結晶裝置表面凝固獲得高純度鋁材；結晶裝置上高純鋁材，藉由脈衝電壓於鋁材與結晶器介面產生部分熔融狀態達到快速取料目的。連續反覆上述程序後，裝有高純鋁材容器，利用滑軌移出純化區域，進行細晶化程序，最後獲得所需高純度細晶化鋁材，整合連續式鋁材純化及細晶化系統，提升高純鋁材生產效率。

The invention provides a continuous system for aluminum purification and grain refinement. A crystallization device is inserted into molten aluminum, where temperature differences induce segregation solidification on the device surface to obtain high-purity aluminum. Pulsed voltage applied at the aluminum–crystallizer interface creates a partial molten state, enabling rapid material extraction. By repeating this process, high-purity aluminum accumulates and is transferred from the purification zone via a sliding rail for grain refinement. This integrated method enhances the efficiency of high-purity aluminum production.
