What are effects of alloying elements on cast iron? Quora

To counter the effects of sulfur, manganese is added because the two form into manganese sulfide instead of iron sulfide. The manganese sulfide is lighter than the melt so it tends to float out of the melt and into the slag. The amount of manganese required to neutralize sulfur is 1.7 sulfur content 0.3%.

An adherent layer of manganese dioxide is deposited on the anode and when the thickness of the deposit reaches a thickness of 10-30 mm or more, the anode is removed from the cell and stripped from the anode by impact, i.e. by hammering or even using an explosive. After cleaning, the anode is replaced in the cell and electrolysis is resumed.
