How Steel is Made from Iron: An Overview
The coke acts as a reducing agent, separating iron from oxygen to produce molten iron. This process generates carbon dioxide as a byproduct, and the resulting molten iron, called pig iron, is collected at the bottom. Basic Oxygen Furnace. The pig iron from the blast furnace is then transferred to the basic oxygen furnace.
