一种去除高温铝液中气体与杂质的方法
摘要：
本发明涉及一种去除高温铝液中气体与杂质的方法，属于冶金技术领域。将超声波设备中的超声波探头伸入到高温铝液中，至高温铝液层下8~13cm，控制超声波设备功率为900W~1600W，超声15~30min后得到除去气体与杂质的高温铝液。本发明采用去除高温铝液中气体与杂质的方法，利用了超声波的机械效应和空化作用，利用冲击波，小气泡、空穴、震荡等，分散较大的硬质氧化颗粒，并吸附氢和杂质，气泡上升过程中，将氢和杂质带出铝液表面，达到去除氢和杂质的目的。
摘要（英）：

The invention relates to a method for removing gas and impurities in high temperature aluminum liquid, and belongs to the technical field of metallurgy. An ultrasonic probe in ultrasonic equipment stretches into the high temperature aluminum liquid at 8-13cm below a high temperature aluminum liquid layer, the power of the ultrasonic equipment is controlled to be 900 W-1600 W; after 15-30 minutes of ultrasonication, the high temperature aluminum liquid for removing the gas and impurities is obtained. The invention adopts the method for removing the gas and impurities in the high-temperature aluminum liquid, utilizes mechanical effects and cavitation of ultrasonic waves, and uses shock waves, small bubbles, holes, vibrations, etc. to disperse larger hard oxide particles and adsorb hydrogen and impurities; during the process of bubbles rising, the hydrogen and impurities are carried out of the surface of the aluminum liquid to achieve the purpose of removing the hydrogen and impurities.
