Coke is an important metallurgical raw material, typically produced by high-temperature carbonization of coal. It is a solid fuel with high carbon content, primarily used in the blast furnace ironmaking process within the metallurgical industry. The main component of coke is fixed carbon, with a content usually exceeding 85%, along with volatile matter and ash. Inside the blast furnace, coke reacts with iron ore at high temperatures, undergoing a series of complex physical and chemical transformations that ultimately reduce iron oxides in the ore to metallic iron.
