The ultimate analysis of the pig iron gives 93.8% Fe, 4% C, 1.2% Si, 1% Mn. For every ton of
pig iron produced, 1750 kg of iron ore and 500 kg limestone are used and 4200 m3 of flue gas
is produced. The rational analysis of flue gases gives 58% N,, 26% CO, 12% CO,, 4% H,O
Calculate the quantity of coke used per ton of pig iron
Calculate the composition of the slag
• Calculate the air consumption per ton of pig iron
