Anode Steel Stub Assembly

The anode steel claw is a key conductive component in an aluminum electrolytic cell, responsible for transmitting powerful direct current from the anode guide rod to the pre-baked anode carbon block. Its performance is directly related to the operational efficiency, stability and energy consumption level of the electrolytic cell.

Product Overview

This product is specially designed for the demanding aluminum electrolysis process. It is manufactured with an optimized structure, carefully selected materials and advanced technology to ensure outstanding electrical conductivity, mechanical strength and thermal fatigue resistance, thereby helping customers achieve a longer service life, higher current efficiency and reduced maintenance costs.

Core features and advantages

Outstanding conductivity efficiency

Material: Made of high-quality low-carbon steel (such as Q235 or equivalent materials), it features low resistivity and low power loss.

Design: The claw arm cross-section has been scientifically calculated. Under the premise of ensuring mechanical strength, the current density distribution has been optimized to reduce ineffective power consumption.

Extraordinary mechanical and thermal shock resistance performance

Structure: The unique "claw-shaped" structure design features high resistance to bending and deformation, capable of withstanding the weight of anode carbon blocks and mechanical stress during the production process.

Heat resistance: Specialized heat treatment processes eliminate internal stress, enabling the product to maintain structural integrity during repeated thermal cycles ranging from room temperature to nearly a thousand degrees Celsius, effectively preventing brittle fracture.

Long-lasting durability and stability

Welding technology: The connection between the claw arm and the crossbeam adopts a full penetration welding process, and the weld joint is ensured to be defect-free by non-destructive testing (such as ultrasonic or X-ray), fundamentally eliminating the risk of cracking during use.

Corrosion resistance: A dense oxide layer can form on the surface of components in contact with high-temperature electrolyte vapor, slowing down further corrosion.

Optimized energy consumption and economy

The low resistance characteristic directly translates into lower power consumption, which helps to reduce the production cost per ton of aluminum.

A longer service life and stable performance reduce the frequency of replacement, lower maintenance costs and downtime.
