Can We Make Steel Without Coal? Coal Action Network Aotearoa

Apr 24, 2013About half of the carbon in the coke combines with the oxygen from the iron ore to make CO2. The rest of the coke is burned in a blast of air in the blast furnace to provide the required high temperature; making more CO2. The resulting pig iron typically contains 2.5-4.5% carbon, making it relatively brittle and unsuitable for most uses.

Comparison of the Mechanical Properties of Steel and

By the late 1700's, pig iron was being refined in puddling furnaces, which allowed for excess carbon to be oxidized out of the mix. As the carbon oxidized out, the melting point of the iron would rise and bits of hardened metal would form on the surface. Skilled workers called Puddlers would remove the bits and place them together to be hammered in a forge. The wrought iron was then run through a rolling mill to
