Preparation method for rapidly improving boron absorptivity of aluminum alloy ingot blank

The invention discloses a preparation method for rapidly improving the boron absorptivity of an aluminum alloy ingot blank, which comprises the following steps of: optimizing the smelting process before casting, namely adding an aluminum-boron alloy in the smelting process, fully stirring and then refining to ensure the adding effect of the aluminum-boron alloy, thereby improving the boron absorptivity of the aluminum alloy ingot blank. Therefore, under the condition that aluminum alloy components are not subjected to other adjustment and optimization, the effective absorption rate of the aluminum alloy ingot blank to the boron element is improved, and then the electric conductivity of the obtained aluminum alloy material is improved. 本发明公开了一种快速提升铝合金锭坯硼元素吸收率的制备方法，其是通过优化铸造前的熔炼过程，即在熔炼过程中加入铝-硼合金，并经充分搅拌后再进行精炼，以确保铝-硼合金的添加效果，从而在铝合金成分不做其他调整优化的情况下，提高铝合金锭坯对硼元素的有效吸收率，进而提升所得铝合金材料的导电率。
