Iron | Linus Pauling Institute | Oregon State University
Iron is an essential component of hundreds of proteins and enzymes that support essential biological functions, such as oxygen transport, energy production, and DNA synthesis. Hemoglobin, myoglobin, cytochromes, and peroxidases require iron-containing heme as a prosthetic group for their biological activities.
THE BLAST FURNACE
They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron. The stock level is constantly 'topped up'. Molten iron ore is 'tapped' at the bottom of the blast furnace, poured into the iron ladle and removed for use. The slag is removed at the tap hole.
How Iron and Steel Work
One is the huge availability of iron ore. The second is the accessibility of vast quantities of oil and coal to power the production of iron. Without iron and energy, we probably would not have gotten nearly as far as we have today. Explore the links on the next page to learn even more about iron and steel.
