Electric Arc Furnace Steelmaking with Submerged Mixed Injection

This book focuses on the study of electric arc furnace (EAF) steelmaking with submerged injection. The new EAF process with submerged mixed injection was first proposed and applied by the authors. It analyzes the mechanism of submerged O2-CaO and carbon powder injection, the impact characteristics of submerged gas-solid injection and the fluid flow characteristics of EAF molten bath with submerged gas-solid injection. The industrial application of EAF steelmaking with submerged gas-solid injection was introduced. Finally, the book reviews the recent innovations and advances of injection metallurgy in EAF steelmaking. It also proposes a possible future process for cyclic utilization of CO2 in EAF-LF steelmaking process. This book provides basic data support for the industrial application of EAF steelmaking with submerged mixed injection for researchers, engineering and technical personnel and industrial professionals.

Provides highly practical reference materials for global Iron & Steel companies to optimize the EAF steelmaking process Is a professional book on the new EAF steelmaking process with submerged mixed injection Proposes possible future process for cyclic utilization of CO2 in EAF-LF steelmaking process
