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.

Steel - Open-hearth steelmaking | Britannica.com
Steel - Open-hearth steelmaking: Though it has been almost completely replaced by BOF and EAF steelmaking in many highly industrialized countries, the open hearth nevertheless accounts for about one-sixth of all steel produced worldwide. The open-hearth furnace (OHF) uses the heat of combustion of gaseous or liquid fuels to convert a charge of scrap and liquid blast-furnace iron to liquid steel.

Bessemer process - Wikipedia
The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace.The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten.
