Abstract
In the steelmaking process, impurities are removed from molten steel, and alloying elements are added. For example, oxidation refining to remove impurities, such as C, Si, and P into slag; reduction refining to remove O and S by adding Al and Ca; and vacuum degassing to remove gas components, such as N, into the gas phase are industrially performed. Thermochemistry is the academic basis of these processes, and examples of impurity removal, inclusion control, and utilization of waste scrap in the steelmaking process are discussed in this chapter.
