Book Description
In recent years, improving the sustainability of the steel industry and reducing its CO2 emissions has become a global focus. To achieve this goal, further process optimization in terms of energy and resource efficiency and the development of new processes and process routes are necessary. Modeling and simulation have established themselves as invaluable sources of information for otherwise unknown process parameters and as an alternative to plant trials that involves lower costs, risks, and time. Models also open up new possibilities for model-based control of metallurgical processes. This Special Issue focuses on recent advances in the modeling and simulation of unit processes in iron and steelmaking. It includes reviews on the fundamentals of modeling and simulation of metallurgical processes, as well as contributions from the areas of iron reduction/ironmaking, steelmaking via the primary and secondary route, and continuous casting.

Book Description
The numerical simulation of sheet metal forming processes has become an indispensable tool for the design of components and their forming processes. This role was attained due to the huge impact in reducing time to market and the cost of developing new components in industries ranging from automotive to packing, as well as enabling an improved understanding of the deformation mechanisms and their interaction with process parameters. Despite being a consolidated tool, its potential for application continues to be discovered with the continuous need to simulate more complex processes, including the integration of the various processes involved in the production of a sheet metal component and the analysis of in-service behavior. The quest for more robust and sustainable processes has also changed its deterministic character into stochastic to be able to consider the scatter in mechanical properties induced by previous manufacturing processes. Faced with these challenges, this Special Issue presents scientific advances in the development of numerical tools that improve the prediction results for conventional forming process, enable the development of new forming processes, or contribute to the integration of several manufacturing processes, highlighting the growing multidisciplinary characteristic of this field.

Book Description
"Continuous steel production has the potential to lower the cost of steelmaking as compared to current batch operations. However, experiences from past attempts to develop and commercialize continuous steelmaking processes show that there are several engineering hurdles to overcome. The objective of this research was the development of a fully continuous steelmaking process that would incorporate the lessons from past experiences, address the foreseen challenges, and meet the requirements to justify the possible replacement of the current EAF-LMF steelmaking route. The design of the new process consists of five interconnected vessels. Preheated scrap would be continuously charged, melted, and superheated in an AC Consteel® EAF. Refining under oxidizing conditions would be accomplished in the EAF and in the second vessel called Oxidizer. Reducing conditions would exist in the subsequent vessels (Reducer, Finisher, and tundish). Continuous de-O, de-S, and alloying would be accomplished in the cone-shaped Reducer before additional de-S and alloy additions as well as inclusion floatation and homogenization in the Finisher would ensure a continuous stream of quality steel into the tundish. The invention of this work is three new refining vessels that connect the proven Consteel® EAF to a tundish, supporting fully continuous operation, and adopting the functions of a typical batch LMF. Each continuous reactor would operate at near-equilibrium conditions during steady-state operations. Performance of the new refining vessels was simulated based on fluid-flow, thermal, and kinetic-thermodynamic models that were verified with industrial measurements during the ladle refining at two LMF's. These simulations addressed the foreseen challenges and predicted that the new continuous steelmaking process could meet or exceed current steelmaking requirements. It is expected that the operation of the new continuous steelmaking process would decrease the cost of steelmaking due to increased metallic yield, improved refining, and increased efficiency. The major result of the evaluation of the ladle refining data is the quantified correlation between the mass transfer rate constant and measurable operational parameters. The value of the mass transfer rate constant is paramount for the chemical performance of each continuous refining vessel. Furthermore, the effect of the FeO concentration in the slag and the slag basicity on the de-S rate was quantified. Frequent measurements during SiMn additions in a ladle with bottom, off-center argon injection demonstrated that this alloy rapidly melts and mixes into the steel bath"--Abstract, leaf iv

Book Description
This book deals with metal processing and its numerical modelling and simulation. In total, 21 papers from different distinguished authors have been compiled in this area. Various processes are addressed, including solidification, TIG welding, additive manufacturing, hot and cold rolling, deep drawing, pipe deformation, and galvanizing. Material models are developed at different length scales from atomistic simulation to finite element analysis in order to describe the evolution and behavior of materials during thermal and thermomechanical treatment. Materials under consideration are carbon, Q&T, DP, and stainless steels; ductile iron; and aluminum, nickel-based, and titanium alloys. The developed models and simulations shall help to predict structure evolution, damage, and service behavior of advanced materials.
