The molten iron ran down the main channel (the Sow) and fed hundreds of moulded depressions in the sand (the Pigs). Slag floats on top of molten iron so the process of tapping the furnace starts with raking off the slag through the slag notch then opening up the lower tap hole to allow the molten iron to run down to the pig beds. Sep 10 2009 · At this point the liquid iron typically flows through a channel and into a bed of sand. Once it cools this metal is known as pig iron. To create a ton of pig iron you start with 2 tons (1.8 metric tons) of ore 1 ton of coke (0.9 metric tons) and a half ton (0.45 metric tons) of limestone.
