摘要： The invention relates to a device (50) and a method for short-circuiting a specified electrolysis in a row of electrolysis cells intended for the production of aluminum. This device includes a bridging member (60) including at least two opposite contact arms and at least one bridging conductor electrically that electrically connects the contact arms. The contact arms are shaped like a wedge. The device further includes a clasping member (70) including a frame and a least two opposite thrust members. The clasping member (70) is fit to embrace the bridging member (60) so that each thrust member bears on each contact arm and so that, upon moving the contact arms with respect to the clasping member, each thrust member urges the corresponding contact arm towards the conductors (201, 202) inserted between the contact arms, so as to create and secure a short-circuit. The invention makes it possible to short-circuit electrolysis cells with increased amperages.
摘要翻译：本发明涉及一种装置（50）和用于使用于生产铝的一排电解槽中的特定电解短路的方法。该装置包括桥接构件（60），其包括至少两个相对的接触臂和至少一个电连接接触臂的桥接导体。接触臂的形状像楔形。该装置还包括包括框架和至少两个相对的推力构件的夹紧构件（70）。夹紧构件（70）被配合成包围桥接构件（60），使得每个推动构件承载在每个接触臂上，并且使得当相对于夹紧构件移动接触臂时，每个推动构件推动相应的接触臂朝向插入在接触臂之间的导体（201,202），以产生并确保短路。本发明可以使电解液的电解质电流短路。

摘要： Process for manufacturing alumina trihydrate by alkaline attack of bauxite, following the general steps of the Bayer process, and during which, after settling and before decomposition, the aluminate liquor undergoes a filtration, known as security filtration, so that at the end of the filtration it contains less than 10 mg/l of insoluble particles, characterized in that, during said security filtration, a filtration device is used that comprises a zone in which the liquor is subjected, after passing through said filtration media, to a pressure greater than 2 bar, preferably greater than 3 bar. Preferably, this device also comprises a zone in which the liquor is subjected, before passing through the filtration media, to a pressure greater than 5 bar, preferably greater than 6, typically in the vicinity of 7 bar. In this way, the aluminate liquor can be kept at a high temperature during the security filtration, typically greater than 130° C., preferably greater than 140° C., and be brought to a high degree of supersaturation Rp, typically greater than 1.25, without risk of reversion.
