Bessemer converter, schematic diagram. 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 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 ...

The current operating practices of BFs with pulverized coal injection for Asian and European mills and natural gas injection for US and Russian mills are retained even when the EU's 2021 average carbon price of 65 /t CO2 is applied globally. As the carbon price rises to 85 /t CO2, a switchover to pellets leads to optimal costs for BFs.
