The Role of Coke in Steel Making Process
Thus, coke plays a dual role in the blast furnace: it sustains the fire that melts iron ore and contributes to the chemical reactions that transform iron ore into a base metal for steel making. Furnace operators meticulously manage coke's presence to maintain the furnace's thermal efficiency and overall productivity.
Iron Making: Smelting
In 1646, the original blast furnace roared to life, lit with a 3000 degree fire that was kept burning 24 hours a day for months at a time. The blast furnace is where bog ore was smelted to create cast iron "pig" bars, so named because liquid cast iron was fed from a larger trench into smaller trenches as a mother sow to suckling pigs.
