The diagram above shows the inputs (left side) and outputs (right side) of an iron blast furnace. Create a
material balance table using the compositions above, and the following conditions:
The burden has 54% Fe. The Fe ratio in Fe,O, and Fe,O. is 1:1.
• The input has 450 kg moisture
• 850 kg slag is produced per 1000 kg pig iron
1600 kg of coke is consumed per 1000 kg of ore. (coke composition: 94% carbon and 4%
moisture)
Assumptions:
1. All O, is consumed in the process.
2. The iron oxides are reduced indirectly.
3. Nz, H;0, and Al;0, are all inert.
4. All Fe in burden reports to pig iron.
