本文介绍了法国沃尔普(Voreppe)彼西湼铝研究中心发明的铝液处理高效现代新方法。它是利用一种新的旋转喷射器,喷入惰性或活性气体(即Ar或Ar+Cl_2),使气体分散成细小气泡并对金属和气体混合物进行搅拌。此种旋转器的高效率,可除去溶解在铝液中的氢、碱和碱土金属以及非金属夹杂物等。旋转器是Alpur精炼装置的主要组成部分,其新优点是:①具有可倾机构,能倒空 This article presents a new, highly efficient, modern approach to the treatment of molten aluminum that was invented at the Biecnoe Aluminum Research Center in Voreppe, France. It utilizes a new rotary jet that injects inert or reactive gas (ie, Ar or Ar + Cl_2) to disperse the gas into fine bubbles and to agitate the metal and gas mixture. The high efficiency of this rotator removes hydrogen, alkali and alkaline earth metals and non-metallic inclusions dissolved in molten aluminum. Rotators are the main components of the Alpur refining unit and have the following new advantages: ① with a tiltable mechanism that empties
