    How much of the coal in a blast furnace is actually necessary for the carbon impregnation, as opposed to supplying the heat via combustion? Steel contains only a few percent carbon by weight, so it doesn’t seem like much carbon is needed (not to mention that the carbon in steel is essentially sequestered).
