Portion's aluminium welding, lower part girder steel and explosion weldering transition block lower part welded steel, using explosion weldering transition block as top aluminum guide
The anode conducting device made from transition is connected with lower part steel pawl when applied to Aluminum Electrolysis Production since transition block two is welded in explosion
The welding of non-tunneling boring is welded in side, can increase the contact resistance of both sides joint face, and the energy consumption during Aluminum Electrolysis Production also can be corresponding
Increase, meanwhile, by traditional welding process, explosion weldering both sides welding action time is longer, aluminum steel faying face in explosion weldering transition block
Intensity can reduce, influence the follow-up service life of whole guide rod, while make anode rod efficiency by traditional welding process and improve
It is more difficult.
In actual use, aluminium/steel interface temperature can arrive 350 degree Celsius to conductive anode rod, while aluminium/steel interface needs
Bear the weight of girder steel, steel pawl and lower anode carbon block, therefore aluminium/steel interface is the most weak link of conducting rod, aluminium/steel interface
Bond strength and stress affect the service life of conducting rod, how to improve conducting rod whole service life and need
It solves the problems, such as.
Rod iron and girder steel in traditional welding steel pawl, most of completed by bevel application electric arc welding, weldering
Junction product only has groove one to enclose, and can not form full face welding, welding manner required time length, high energy consumption, there are welding cigarettes
Dustiness contaminates.
During conventional pilot electric pole use, since steel claw position is heated, distortion is easily deformed, and then influences making for conducting rod
Use the service life.
