The aluminum clad steel electrical transition joint can greatly reduce electrical resistance and corrosion and improve performance under high temperature. Phohom successfully developed AI-Ti-St joint which possesses even higher bonding strength. Therefore it can bear higher temperature and work longer.
To meet the application needs of customers, Phohom developed an aluminum-titanium-steel electrical transition joint, which greatly improved the stability of the connection of steel claws and aluminum guide rods and can maintain strength and electrical efficiency for a long time in a high temperature.
Also our electrical transition joints can be used in other metal smelting using other combinations of dissimilar metals to reduce the maintenance cost while maintaining efficient operation.
Aluminum Smelter
- Electrical Transition Joints
- In the pre-baked electrolytic cell of the electrolytic aluminum plant, the anode group is mainly composed of aluminum guide rod, steel claw and graphite anode rod, in which the aluminum guide rod and steel claw are connected by Al-St explosive welding block.
