Consider pure  as a feed, hot metal exits at  and hot metal contains . The value of   Substituting the values of  (See case b).we get.



.

Carbon consumption product .

Graphical representation

Let us rewrite equation 9 as



.

One can plot  as ordinate against . The slope of the line  will pass through points

A blast furnace operates with  and pig iron Contains . feedconsists of  gangue.



We draw a line with slope 2.55, we determine



Top gas composition .
