Problems solved by technology
[0004] exist figure 1 Among them, when the aluminum-steel explosive composite sheet is welded with the anode steel claw and the anode guide rod respectively, the local temperature at the welding point is as high as 700-900°C. Since the aluminum-steel explosive composite sheet is thinner and its composite surface is larger, therefore, The heat dissipation of the aluminum-steel explosive composite sheet along the composite surface is poor, and its temperature sometimes exceeds 400°C, and some small cracks will occur, which may cause the aluminum-steel explosive composite surface to fall off during the use of the anode block
[0005] In addition, during the electrolysis process, due to the high current of individual anode blocks, the anode steel claws will become red, making the aluminum-steel explosive composite surface use temperature ≥ 400 ° C, which may also cause the aluminum-steel explosive composite surface to fall off
[0006] During the electrolytic production process, the aluminum-steel explosive composite surface falls off not only causing the anode block to be scrapped, but more importantly, affecting the stable production of the electrolytic cell

Description
Technical field: [0001] The invention relates to an explosive connection structure between an anode steel claw of an electrolytic cell and an anode aluminum guide rod. technical background: [0002] The anode block used in the aluminum electrolytic cell is cast from the anode carbon block and the anode guide rod assembly. The anode guide rod assembly consists of two parts: the anode steel claw and the anode aluminum guide rod. [0003] At present, the anode steel claw of the anode guide rod assembly and the anode guide rod are welded by an anode explosion disc, and its structure is shown in figure 1 . Since the anode explosive sheet is composed of 12-14mm aluminum plate (2) and 38-40mm steel plate (1) in an explosive way, and the aluminum-steel explosive composite surface is a fine tooth-shaped joint surface, the fine tooth-shaped joint surface and the anode The direction of the tensile force of the explosive disc is vertical, and its service temperature is ≤400°C.
