A kind of anode steel claw guide rod group

Abstract

The invention provides an anode steel claw guide rod set. The anode steel claw guide rod set comprises an anode steel claw guide rod and an anode steel claw. The anode steel claw guide rod is providedwith a hoisting part. A frame structure defined by a good conductor and steel plates meeting the strength requirement is adopted as the anode steel claw guide rod to be directly connected to the anode steel claw, and the good conductor plate is attached to one side face of the anode steel claw guide rod; and the anode steel claw guide rod is of the frame structure defined by the good conductor plate and the steel plates, wherein the bottom of the frame structure is hollow. The phenomenon of arc discharge cannot happen to the anode steel claw guide rod set, the service life is long, contact resistance is hardly achieved for the anode steel claw guide rod set, and electrical losses are few. The anode steel claw guide rod set is simple in structure, low in manufacturing cost and convenient to install. The anode steel claw guide rod set is adopted for aluminum electrolysis, and environment protection is facilitated; and connection between the anode steel claw guide rod and the anode steelclaw is firm and stable, the phenomena of falling-off and tearing cannot happen, aluminum materials can be greatly saved, and the material cost of the anode steel claw guide rod is greatly reduced.

Description

technical field [0001] The invention relates to an anode steel claw guide rod group. Background technique [0002] In the aluminum electrolytic production process, the anode steel claw guide rod group as a conductive unit plays a vital role in the uniformity of the current distribution in the electrolytic cell and the stability of the electrolyte system, and its working temperature is 400-900 ° C. The traditional anode guide rod set consists of an anode steel claw guide rod, an aluminum / steel explosive block and an anode steel claw. The anode steel claw is made of ordinary carbon steel, the anode steel claw guide rod is made of aluminum, and the anode steel claw guide rod is Connection with anodized steel claws by aluminum / steel explosive welding nuggets. For example, the anode guide rod set disclosed in CN2816054Y includes a steel column, a steel claw base, and an aluminum guide rod connected to the steel claw base through an explosion welding block, and the steel column a...

AI Technical Summary

Problems solved by technology

The traditional anode guide rod set has many disadvantages, one is that the size of the aluminum / steel explosion welding block is small, resulting in a high voltage drop, and due to the inconsistency of the thermal expansion coefficient of the aluminum / steel, the thermal expansion of the steel beam causes the anode steel claws to deform inwardly Or pull off the anode carbon block, which will affect the normal and stable production of the electrolytic cell; the second is that the connection between the bus bar and the anode steel claw guide rod is prone to arcing, and the service life is short; the third is that the contact resistance is large, the power loss is large, and the material consumption Large and costly; Fourth, the existing aluminum electrolysis production enterprises all need to use aluminum / steel explosion welding nuggets, which consume a large amount of aluminum / steel explosion welding nuggets and are likely to pollute the environment after being scrapped
