This book intends to summarize the current situation at home and abroad about the treatment and consumption of various metallurgical wastes and domestic waste fertilizers and their products through metallurgical processes. It collects the process characteristics of the whole metallurgical process from sintering, blast furnace, electric furnace, converter, and other aspects, as well as the process parameters for treating various solid wastes, solves the problems that may be encountered in the relevant processes, and puts forward corresponding solutions, including the transformation of the process flow or the addition of some pre-treatment links. In addition, this book also evaluates some important production and digestion processes and puts forward relevant suggestions for readers to have a more comprehensive thinking. University teachers, graduate students, researchers, and engineers engaged in iron and steel metallurgy process, especially those who use iron and steel process to absorb metallurgical solid waste and domestic solid waste together, will be of great help to them.
