There are three types of merchant pig iron, which are as follows: Basic pig iron – This is used in electric arc furnace for the purpose of steel making. This is achieved by remelting pig iron, often along with substantial quantities of steel and scrap iron, removing undesirable contaminants, adding alloys and adjusting of the C content. (v) Replacement of Pig-Iron: The spongy iron can also replace pig-iron for large iron foundries where there is facility for hot blast cupolas. (vi) Shortage of Coking Coal: 216 views.
