Blast furnace produces pig iron of composition Fe 94%, Si2%, Mn 0.5% and C 3.5% by reduction smelting of iron ore, coke and limestone. The analysis is as follows: Iron ore : Fe20, 78%, SiO2 8%, Alz03 5%, MnO 2% H20 7% Coke : 86% C and 10% S and 4% Al,03; Amount is 600 Kg per ton of pig iron Limestone : pure CaCO, to produce a slag of 45% Cao Calculate: a) Amount of ore/ton of pig iron b) % of total Si 0z and of Mno reduced in the furnace c) Amount of slag/ton of pig iron and its % composition.

Transcribed Image Text:Blast furnace produces pig iron of composition Fe 94%, Si2%, Mn 0.5% and C 3.5% by reduction
smelting of iron ore, coke and limestone. The analysis is as follows:
Iron ore : Fe,0, 78%, SiO, 8%, Alz0, 5%, MnO 2% H20 7%
Coke : 86% C and 10% S and 4% Al,0,; Amount is 600 Kg per ton of pig iron
Limestone : pure Caco, to produce a slag of 45% Cao
Calculate:
a) Amount of ore/ton of pig iron
b) % of total Si 0z and of Mn0 reduced in the furnace
c) Amount of slag/ton of pig iron and its % composition.
