This chapter describes the ironmaking technology and outlines the process essentials. The main focus was given to the blast furnace process, which is still the dominating technology for ironmaking. The emerging alternative ironmaking technologies-direct reduction and smelting reduction-are only briefly introduced, and will be described in a separate chapter in this book series.In the beginning, there is a short introduction to the ironmaking history followed by a general description of the blast furnace ironmaking process, and its role in the global steelmaking industry. The readers are guided from the equipment aspects of the blast furnace and its auxiliary facilities, to the internal structure and materials interactions within the furnace. The types of raw materials (iron ore, coke and coal, and other fuels), their preparation and properties for the blast furnace process are also described. Furthermore, the aspects of process control, the process performance, and energy consumption are evaluated. In the end, the development trend of various ironmaking technologies is discussed.
