iron ore to steel process

Open hearth furnace Wikipedia

Open hearth furnace Wikipedia

The oxygen in iron oxide and other impurities decarburize the pig iron by burning excess carbon away, forming steel. To increase the oxygen contents of the heat, iron ore can be added to the heat. The process is far slower than that of Bessemer converter and thus easier to control and sample for quality assessment. Preparing a heat usually takes 8 h to 8 h 30 min to complete into steel.
