Particularly in an Electric Arc Furnace I have seen carbon boil occuring . I understand the reaction is very vital but what is it's utility? A detailed answer to this is most welcome. The internet says that it promotes slag metal reactions and temperature homogeneity. But my question is how that is it.There are many elements present but why particularly do I need to boing carbon? Why not Si, P etc. This is where the problem seems to be very confusing for me.
