摘要： The amount of electrically conductive material in the bottom floor lining of a conventional aluminum reduction cell is reduced by using a non-conductive lining material in its place. The non-conductive material separates the remaining electrically conductive regions from the sidewall linings of the cell and preferably confines the electrically conductive material to the "anode shadow" region of the cell floor. The non-conductive material preferably comprises a particulate alumina mixture made up of large shapes which firmly compact together and smaller particles which fill the remaining voids. Optionally, the mixture may be bonded together with amorphous alumina, in which case the mixture can also be used for cell wall linings. The linings can be used in reduction cells of conventional design and reduces undesirable magnetohydrodynamic effects as well as pollution hazards caused by conventional carbonaceous cell linings.

摘要： The amount of electrically conductive material in the bottom floor lining of a conventional aluminum reduction cell is reduced by using a non-conductive lining material in its place. The non-conductive material separates the remaining electrically conductive regions from the sidewall linings of the cell and preferably confines the electrically conductive material to the "anode shadow" region of the cell floor. In another embodiment joints between the conductive and non-conductive regions are positioned such that they are covered by cell freeze (solid electrolyte) during operation of the cell. This prevents liquid cell contents penetrating the joint and adversely affecting the cell lining, thus shortening the life of the cell. The non-conductive material preferably comprises a particulate alumina mixture made up of large shapes which firmly compact together and smaller particles which fill the remaining voids. Optionally, the mixture may be bonded together with amorphous alumina, in which case the mixture can also be used for cell wall linings. The linings can be used in reduction cells of conventional design and reduces undesirable magnetohydrodynamic effects as well as pollution hazards caused by conventional carbonaceous cell linings.
摘要翻译：传统的铝还原电池的底层衬里中的导电材料的量通过在其位置使用非导电衬里材料来减少。不导电材料将剩余的导电区域与电池的侧壁衬里分开，并且优选将导电材料限制在电池板底板的“阳极阴影”区域。在另一个实施例中，导电区域和非导电区域之间的接头被定位成使得它们在电池工作期间被细胞冷冻（固体电解质）覆盖。这防止液体细胞内含物穿透关节并且不利地影响细胞衬里，从而缩短细胞的寿命。非导电材料优选包括由大的形状组成的颗粒状氧化铝混合物，其牢固地压实在一起，并且填充剩余空隙的较小的颗粒。任选地，混合物可以与无定形氧化铝结合在一起，在这种情况下，混合物也可用于细胞壁衬里。衬里可用于常规设计的还原电池，并减少不期望的磁流体动力学影响以及由常规碳质电池衬垫引起的污染危害。
