6. During Basic Oxygen Process to manufacture low carbon stainless steel,
600 kg of cast iron (6% of carbon), 500 kg of cast iron (5% of carbon) and
400 kg of cast iron (4% of carbon) will be mixed with household scrap of
steel (2% of carbon) to generate 1800 kg of final product of steel with 0.5%
of carbon.
a. Write down material balance for iron in feed and final product. Then
calculate x.
b. Write down material balance for carbon in feed and final product.
Then calculate total carbon removed (kg) with the slag.
