特效精炼剂，通常指的是一种用于特定工业过程，如金属熔炼，以提高材料纯度和质量的化学制剂。在铝熔炼等工艺中，精炼剂的主要作用是清除铝液内部的氢气和浮游的氧化夹渣，从而使铝液更为纯净。

Special refining flux usually refers to a chemical agent used in a specific industrial process, such as metal smelting, to improve the purity and quality of a material. In aluminium smelting and other processes, the main function of refining agent is to remove hydrogen and floating oxidation slag inside the aluminium liquid, so as to make the aluminium liquid more pure.
