Abstract
Secondary metallurgy is a very central part of the modern steelmaking process. It means a variety of different unit processes via which the final composition and even properties of steels are determined and adjusted. Typical unit processes in secondary steelmaking are deoxidation, desulfurization, degassing, decarburization, alloying and trimming additions as well as heating and temperature adjustment. In this chapter, the fundamentals of thermodynamics and kinetics of unit processes are described. Further, the development and principles of the most common technological methods to carry out processes are discussed including gas stirring, vacuum facilities, ladle furnace and chemical heating, and techniques for alloying and trimming additions.
