Large-tonnage light alloy melt real-time purification method and system

The invention discloses a large-tonnage light alloy melt real-time purification method and system, and relates to the technical field of aluminum alloy purification. The method applied to the large-tonnage light alloy melt real-time purification system comprises the steps that an anti-seepage type air brick is pre-buried at the bottom of a smelting furnace, hydrogen content data of an alloy melt are collected in real time through an online hydrogen measuring instrument, dispersed and bubbly refined argon is blown in through the online hydrogen measuring instrument in stages, the content of hydrogen in molten aluminum is effectively reduced, and the purity of the molten aluminum is improved. The liquid level of the alloy melt is protected from oxidation. Therefore, the problems of high element burn-out rate, high hydrogen content, more inclusions and low production efficiency due to natural gas heating and smelting in the preparation of the light alloy in the prior art are solved. 本发明公开了一种大吨位轻合金熔体实时净化方法及系统，涉及铝
