EP4276226A2 CATHODE CURRENT COLLECTOR FOR A HALL-HEROULT CELL 审中-实审转让
公开(公告)号：EP4276226A2

摘要： The invention relates to an electrolytic cell (1) for the production of aluminium (2) including collector bars structure modifications (13,14,15,16) under the cathode (4), namely a copper collector bar held in a U-shaped profile or directly embedded into the cathode. This leads to an optimized current distribution in the liquid aluminium metal (2) and/or inside the carbon cathode allowing for operating the cell at lower voltage. The lower voltage results from either a lower anode to cathode distance (ACD), and/or to lower voltage drop inside the carbon cathode from liquid metal to the end of the collector bar.

摘要翻译：本发明涉及用于生产铝（2）的电解电池（1），其包括在阴极（4）下方的集电条结构变型（13,14,15,16），即铜集电条，其保持为U形轮廓或直接嵌入阴极。这导致液态铝金属（2）中和/或碳阴极内部的优化电流分布，从而允许以较低电压操作电池。较低的电压源于较低的阳极到阴极距离（ACD），和/或降低碳阴极内从液态金属到集电极端部的电压降。
