In the Bessemer process, molten pig iron from the blast furnace was charged into a large crucible, and air was blown through the molten iron from below, igniting the dissolved carbon from the coke. As the carbon burned off, the melting point of the mixture increased, but the heat from the burning carbon provided the extra energy needed to keep the mixture molten.

Steel Production - American Iron and Steel Institute
The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal is a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen.
FINEX (steelmaking process) - Wikipedia
FINEX is the name for an iron making technology developed by former Siemens VAI (now Primetals Technologies) and POSCO. Molten iron is produced directly using iron ore fines and non-coking coal rather than traditional blast furnace methods through sintering and reduction with coke. Elimination of preliminary processing is claimed to make the
