During the Industrial Revolution, smelting was the main method used to convert raw iron ore into steel. This procedure entailed heating the ore until it became blazingly hot in a furnace and using pressurized air to initiate oxidation. Doing this created a crude form of steel that needed additional refinement to reach its finished product status.
Towards the end of the 1800s, a shift in the way steel was harvested from iron ore occurred. The Bessemer process, whereby a blast of air was utilized to elimintate impurities from the ore, was much faster and more cost-effective than the conventional smelting procedure. As a result, it suddenly became the go-to means of steel production.
Nowadays, the Basic Oxygen Furnace (BOF) method takes the iron from ore to steel. During this process, oxygen is injected into the ore to oxidize its iron molecules and create steel of excellent quality. This steel is then used for a vast array of purposes.
