The steel story

Their process was known as the Siemens-Martin process, and the furnace as an ''open-hearth'' furnace, in which excess carbon and other impurities are burnt out of pig iron to produce steel. The open hearth process overcame the insufficient temperatures generated by normal fuels and furnaces, enabling steel to be produced in bulk for the first time.
