The direct electricity conducting type movable steel claw with the exchangeable claw head is mainly applied in the field of aluminum electrolysis.

Description

technical field [0001] The invention relates to a direct conductive movable steel claw with a replaceable claw head, which belongs to the technical field of aluminum electrolysis. Background technique [0002] In the traditional aluminum electrolysis industry, the anode aluminum guide rod and the steel claw are welded together by an explosion block. The explosion block is a steel-aluminum composite plate, and the welding surface is not welded with a full cross-section. The conductive cross-section on the welding surface is too narrow, causing the resistivity to rise. The overall conductivity of the steel claws decreases during electrolysis of aluminum, and the traditional explosive block also plays a load-bearing role. When the temperature exceeds 350°C, the explosive block is prone to thermal cracking or even falling off, which seriously affects the production efficiency of electrolytic aluminum. [0003] In the process of aluminum electrolysis, in addition to providing a b...

[0002] In the traditional aluminum electrolysis industry, the anode aluminum guide rod and the steel claw are welded together by an explosion block. The explosion block is a steel-aluminum composite plate, and the welding surface is not welded with a full cross-section. The conductive cross-section on the welding surface is too narrow, causing the resistivity to rise. The overall conductivity of the steel claw decreases during electrolysis of aluminum, and the traditional explosive block also plays a load-bearing role. When the temperature exceeds 350°C, the explosive block is prone to thermal cracking or even falling off, which seriously affects the production efficiency of electrolytic aluminum.

[0003] In the process of aluminum electrolysis, in addition to providing a bracket for the installation of the steel claw, the traditional steel claw beam also acts as a conductive link between the anode aluminum guide rod and the steel claw during the aluminum electrolysis process. Therefore, in the selection of materials At the same time, not only the strength and rigidity of the steel claw beam must be considered, but also higher requirements for the resistivity, and the selection of the resistivity is prior to the strength and stiffness of the steel claw beam, which leads to the steel claw beam in the process of aluminum electrolysis. Inner hooks appear due to heat, causing the carbon block to break easily, and it is necessary to stop to replace the carbon block, which also seriously affects the production efficiency of aluminum electrolysis
