Electrolytic bath cathode steel bar and soft aluminum strip connection configuration structure

Abstract

The invention discloses an electrolytic bath cathode steel bar and soft aluminum strip connection configuration structure, which is characterized in that: cathode steel bars (1) and a soft aluminum strip (5) are connected through connecting plates (2), a steel-aluminum explosive welding block (3) and backing plates (4). Specifically, the cathode steel bars (1) and the connecting plates (2), and the steel-aluminum explosive welding block (3) and the soft aluminum strip (5) are connected by means of welding. The backing plates (4) are located below the connecting plates (2) and the steel-aluminum explosive welding block (3). The connecting plates (2), the steel-aluminum explosive welding block (3) and the backing plates (4) are connected by welding. The connecting plates (2) are rectangular or ''L'' shaped. By means of non-rectangular treatment on the connecting plates, the connecting plates are welded with the end faces and the sides of the cathode steel bars, the welding seam is increased, and the welding contact area is enlarged, thus reaching the purpose of lowering the electrolytic bath cathode drop. And the backing plates below the cathode steel bars and the steel-aluminum explosive welding block play a role of supporting the construction process.

Description

technical field [0001] The invention relates to a connection configuration structure of a cathode steel bar head of an aluminum electrolytic cell and welding parts such as a soft aluminum strip. Background technique [0002] On the existing electrolytic cell, the connecting plate is usually rectangular, one side is welded with the end face of the cathode steel rod, and the other side is welded with the explosive welding block to achieve the purpose of connecting and electrifying. [0003] Common connection configurations of cathode steel rods, connection plates, explosive welding and other components are shown in the attached figure 1 Shown. This configuration structure is limited by the size of the end face of the cathode steel rod, which will affect the current flow area; in addition, because the explosive welding and the cathode steel rod form an angle of 30°, the external dimensions of the connecting plate gradually increase from bottom to top. Therefore, it is necessa...
