Product overview Technical advantages Functional characteristics

Jingwei Technology is one of the main suppliers of special cathode steel rods for electrolytic aluminum enterprises in China, the supply types are: ordinary cathode steel rods, special-shaped cathode steel rods, high conductivity cathode steel rods, copper embedded cathode steel rods, carbon-proof cathode steel rods, steel rod aluminum flexible band welding, etc. Among them, products such as high conductivity cathode steel rod, special cathode steel rod and carbon-proof cathode steel rods have successively obtained national patents.

High conductivity cathode steel rod and embedded copper cathode steel rod can improve the conductivity of the material itself and reduce the bottom voltage drop of the electrolytic cell. It is very beneficial to reduce the horizontal current of the electrolytic cell, reduce the average flow rate of liquid aluminum, improve the working stability of the electrolytic cell, and provide the possibility for further compression of the polar distance.

During the installation of aluminium soft strip welding head for steel rods, the steel side and the cathode square steel and the aluminum soft band side are welded directly to the cathode aluminum bus, which is used to replace the traditional connection mode of explosive block and steel continuous piece. It helps to reduce the voltage drop of the cathode system and provides conditions for reducing the power consumption of tons of aluminum.

Our company strictly in accordance with the requirements of ISO9001 international standard quality management system to regulate the quality management of enterprises. And our company has strict production management process, perfect quality control (QC) and quality assurance (QA) system to ensure product quality.

High conductivity steel rod: High conductivity steel rods have more than 30% higher conductivity than traditional cathode steel rods.

High conductivity cathode steel rods and copper embedded steel rods: They can effectively reduce the horizontal current in the aluminium liquid, slow down the fluctuation of the aluminium liquid, and create conditions for the smooth and efficient operation of the electrolytic cell under low-voltage conditions.

Carbon-proof cathode steel rods: The use of carbon-proof cathode steel rods in high temperature and carbon-rich environments in electrolytic cells will greatly increase material life.

Aluminium soft strip welding head for steel rods:Replacing the traditional explosive block-steel linkage connection between cathode steel rods and bus, the voltage drop at the connection site is reduced by more than 15mv.

It does not change the existing aluminium electrolytic cell furnace construction process and the structure of cathode carbon block, so it has no impact on the production and assembly of cathode carbon block.

High conductivity cathode steel rods/copper embedded steel rods:The voltage drop of the body is greatly reduced, which is conducive to reducing the voltage drop at the bottom of the electrolytic cell.

High conductivity cathode steel rods/copper embedded steel rods: It can reduce the level of current, slow down the fluctuation of the aluminium liquid, which plays a heterogeneous cathode, flow-blocking tank effect.

Carbon-proof cathode steel rods: It helps to reduce carburisation, reduce the intrinsic voltage drop of cathode steel rods at the end of their service life and increase the service life of the rods.
