Steel pawl head and aluminium conducting rod are exploded by aluminum steel welds connection, and such conductive anode rod and anode carbon block are linked together, and form anode
Charcoal block assembly.
In the connection of phosphorus pig iron casting formula, nearly 1700 DEG C of temperature when phosphorus pig iron casting, although the phosphorus pig iron is in steel
The coefficient of expansion is the smallest.But it is much larger than the coefficient of expansion of carbon block.The coefficient of expansion of the phosphorus pig iron is about 15~16 × 10-5/ degree,
The coefficient of expansion of carbon block is 3.7~4.0 × 10-6/ degree, the two difference more than 30 times, so on electrolytic cell the contraction of the phosphorus pig iron with
There is certain gap between carbon bowl, causing the voltage drop between the phosphorus pig iron and carbon bowl is about 150mV.
Existing anode steel claw is all formed by molten steel is integrated poured, and is solid construction.It (is connect with explosion piece by steel pawl head
