Q2- Iron blast furnace smelting composition ore (Fe3O4 70%, Fe2O3 5%, SiO2 10%, P2O5 1%, MnO2 4%, H2O 10%). It produces daily 900 metric tons of iron ore. Sufficient flux is used to give slag containing 24% CaO. Flux is pure limestone. 0.48 tons of coke are used per ton of ore. Coke is 86% carbon, 9% SiO2, 5% water. All the charged P, half of the Mn, and one-fifth of the Si are reduced and go into the pig iron, which by analysis also contains 4% C. 88% of the coke carbon is burned in the tweezers. Do not assume there is iron in the slag. Find:

a) The percentage composition of cast iron

b) The daily weight of molten ore

c) The flow weight used per day

d) the percentage composition of flue gases

Pure FeO is reduced to Fe, and all

Q2- An iron blast furnace smelts ore of the composition (Fe3O470%,Fe2O35%,SiO2 10%,P2O51%,MnO24%,H2O10% ). It produces per day 900 metric tons of pig iron. Enough flux is used to give a slag containing 24%CaO. The flux is pure limestone. 0.48 ton of coke is used per ton of ore. The coke is 86%C,9%SiO2,5%H2O. All the P charged, one-half the Mn, and one-fifth the Si are reduced and go in the pig iron, which also contains by analysis 4% C. 88% of the carbon of the coke is burned at the-tuyeres. Assume no iron in the slag. Find: a) The percentage composition of the pig iron b) The weight of ore smelted per day c) The weight of the flux used per day d) The percentage composition of the flue gases
